the common slipper shell , crepidula fornicata , has many other common names , including common atlantic slippersnail , boat shell , quarterdeck shell , fornicating slipper snail , atlantic slipper limpet and it is known in britain as the " common slipper limpet " .

this is a species of medium-sized sea snail , a marine gastropod mollusc in the family calyptraeidae , the slipper snails and cup and saucer snails .

common slipper shell

fun fact : another common name for the shark’s eye shell is the moon shell .
the slipper shell produces calcium carbonate which is what the actual shell is made up of . the slipper shell is roughly 2 . 5cm to 4cm in diameter . ( dando 1996 )
like a snail this mollusk has just one shell . the common name «slipper» describes nicely the inside of this mollusk . it can reach sizes up to 4 cm .
if more chefs agree with mr . orieux , the atlantic slipper shell just might creep into french cuisine .
common size : up to 50 mm in the atlantic , mediterranean specimens smaller .
sometimes the common atlantic slipper shell is found washed ashore attached to another shell , perhaps an olive shell , or even another crepidula fornicata . the slipper shell often lives in stacks or chains since it likes to attach itself to others of its kind . this makes reproduction convenient . the species in the crepidulidae family are hermaphroditic . during the spawning ( or mating ) season , they alternate sexes . eggs are laid ( 70 - 100 at a time ) in thin - walled capsules which are attached to the substrate ( the base on which the creature lives ) . common slipper shell larvae emerge from these capsules .

the common slipper shell is one of the more common shells found along the rhode island coast . this shell is shaped like an egg or oval that has been cut in half with the top of the shell turned sharply to one side . looking at the underside of the shell , it is easy to see how it got its name . underneath the shell is a ledge to support the internal organs ; this ledge extends about half the length of the animal . different slipper shell species are characterized by different shell textures , including rough , smooth , ribbed , corrugated , and flat . although they have a foot for locomotion , by the time they reach maturity they anchor themselves to a hard substrate and remain stationary .
the atlantic slipper shell is a curious type of sea snail that has spread from the east coast of the united states .
common slipper shells also form stacked aggregations when there is no hard substrate on which to attach . they attach to objects in large numbers and can sometimes suffocate the animal on which they are attached . common slipper shells use their cilia to create water currents that flow through their mantle cavity . they are filter feeders , and as the water passes through the cavity , mucous - covered gills trap various types of phytoplankton and algae . the common slipper shell then uses its radula to remove the food and bring it to its mouth .
notwithstanding this rough treatment , the slipper shell remains the most populous creature in the bay , growing by 10 percent per year .

the snail , a sliver of orange flesh clamped tightly within a shell , tastes somewhat like whelks and scallops , but it has never caught on as common fare .
slipper tails are sold with shell , or as peeled and deveined meats . slipper lobster tails are graded under 1 oz , 1–2 oz , 2–4 oz , 4–6 oz , and 6 - 8 oz . slipper meat is available graded under 1 oz and 1–3 oz .
, class gastropoda ) , in which the humped or flattened shell has a decklike half partition inside . slipper shells occur worldwide in shallow waters . adults are fixed to rocks or live within the empty shells of other mollusks . the common
the common slipper shell looks like a flattened snail that has lost its spiraled shell in favor of a smooth cap . somewhere between 20 and 100 million years ago snails with coiled shells uncoiled their shells and gave rise to slipper shells and limpets . snails with these uncoiled shells do well in the rocky intertidal zone where their ability to cling to rocks with their big foot ( a bigger foot evolved along with that uncoiled shell ) and that smooth low - profile shell that helps waves wash right over them .
a favorite of children , the convex “slipper , ” “boat , ” or “quarterdeck” shell is easy to identify . it looks like a bedroom slipper because of the white plate which partially covers the cavity .
there are many reasons why a cookie could not be set correctly . below are the most common reasons :
limpet , any of various snails ( class gastropoda , phylum mollusca ) having a flattened shell . most marine species cling to rocks near shore . a common american species is the atlantic plate limpet ( acmaea testudinalis ) of cold waters ; the common species of britain and northern europe is patella…
the common atlantic slipper shell ( c . fornicata ) , often called slipper limpet , is about 4 cm ( 1 . 5 inches ) long and yellowish ; it is abundant from nova scotia to texas . in addition , c . fornicata has been introduced to the west coast of the united states , the coastal waters of…

cooking slipper lobster tails and meat immediately after proper thawing yields the best quality .
also known as cappalunga , is a shell shaped like an old - fashioned razor .
fun fact : this extremely small shell usually does not grow longer than one inch .
marketing the slipper shell at home , however , presents a real challenge : persuading a country — and a region — anchored in culinary tradition to adopt a new ingredient .
the fossil record of slipper lobsters extends back 120 million years to the cretaceous period .
alien species the common atlantic slipper snail or slipper limpet crepidula fornicata originates from the east coast of north - america . the species was however brought to europe together with the eastern oyster crassostrea virginica . in belgium , the first slipper limpet was found on 28 september 1911 attached to an oyster in ostend and since the 1930’s , it is seen as a common species along the belgian coast . the slipper limpet has little to no predators here , and can thrive on several types of hard bottoms and shellfish banks . a continued expansion to the north is probably inhibited by temperature : low temperatures during the winter can slow down or inhibit the development of the slipper limpet .

mr . jambon , who has a 5 percent stake in mr . clément’s slipper shell business , said that while some seafood producers remained skeptical , a growing consensus had emerged .
the hard outer shell of a lobster does not grow , thus growth can only be achieved via a process known as molting through which a lobster discards its old shell , expands its size and creates a new shell . during the molting process lobsters are essentially knights without armor , and they are extremely vulnerable to predators until their new shell begins to harden .
slipper shells are related to limpets but can be recognized by one obvious difference visible only if you find an empty shell . instead of the empty dome of a limpet’s shell , they have a shelf that covers half of the dome . this is the structure that makes them resemble a slipper ( or some say a boat ) . that shelf helps to support and protect their internal organs and is thought to be a remnant of that spiraled shell .
the atlantic slipper shell is a filter feeder , and unlike other limpets , which go out and graze on algae , the atlantic slipper shell spends its full life span in the same spot . it has a suction creating foot , which allows it to attach to hard surfaces . it does not require a two - part shell because it uses whatever it is attached to as the other part in a way . the bottom side of the atlantic slipper shell is never regularly exposed . it will attach to rocks , other slipper shells , and even other shelled organisms not of the same species . the atlantic slipper shell is capable of covering an entire seabed in certain areas if the conditions are right ( dexter 1947 ) . it also doesnt seem to have many predators which contributes to its success . these organisms have posed a problem off the coast of england , which will be discussed later in the paper .

the shell is typically coiled , usually dextrally , the axis of coiling being around a central columella to which a large retractor muscle is attached . the uppermost part of the shell is formed from the larval shell ( the protoconch ) . the shell is partly or entirely lost in the juveniles or adults of some groups , with total loss occurring in several groups of land slugs and sea slugs ( nudibranchs ) .
like mussels , jingle shells attach using byssal threads . these threads are secreted by a gland located near the jingle shell ' s foot . they then protrude through a hole in the bottom shell and attach to the hard substrate . the shell of these organisms takes on the shape of the substrate upon which they attach ( for example , a jingle shell attached to a bay scallop will have ridged shells also ) .
shell is oval and up to 5 cm in length . the large shell opening has a shelf , extending half its length . shell is smooth and white , cream , yellow or pinkish in colour with streaks or blotches of red or brown . commonly found in curved chains or stacks made up of several individuals .

but now they are finding their nets weighed down by an invasive species : the crépidule , or atlantic slipper shell , a curious type of sea snail that has spread from the east coast of the united states .
now he is distributing packages of frozen slipper shell flesh to stores and restaurants , and also plans to reuse the calcium - rich shells in construction material and to improve the acidic soil of his native breton coast .
shell is black or purple above and white below , coiled , with a definite raised spire ( but the shell is only about as tall as wide ) , no siphonal notch or canal in aperture , interior of the shell is pearly . animal has an operculum which is thin and horny with spiral lines . columella has two small nodes . the umbilicus is closed by a callus ( picture ) . shell up to 3 cm diameter . the apex is frequently heavily worn , and shell may be encrusted with coralline algae or bryozoans . animal ' s foot is black on the sides . the black on the shell is due to a dark periostracum .
off of the coast of england , slipper shells pose a large problem for the oyster population . the slipper shells will attach themselves with their suction like foot to the shell of the oysters and reproduce right on top of them . this will cause the slipper shells to start one of these stacks discussed above , right on top of the oysters . this is a threat to the oysters because both the oyster and the slipper shells are filter feeders . if an oyster has a bunch of slipper shells growing all around it , the slipper shells will filter out all of the food before the food can reach the oyster . this will eventually starve the oyster and it will die . if enough slipper shells grow on top of the oysters , they also have the potential to crush the oysters and kill them directly . the situation with the slipper shells and the oysters , is very similar to the situation in lake champlain with the zebra mussels and the native mussels .
crepidula onyx , the onyx slippersnail or onyx slipper snail , is a species of sea snail with gills , a marine gastropod mollusc in the family calyptraeidae , the slipper snails and cup - and - saucer snails .
the meat of jingle shells is very bitter , so they are not harvested for food . they are considered common and have not been evaluated for conservation action .
molting is governed by hormones secreted from glands in the eye stalks . before molting , lobsters feed heavily and store fat . next the animal produces a soft shell underneath its existing shell and it soon seeks an area where it can hide . shortly afterward the old shell begins to fracture and the animal climbs out of its old shell . in some instances the lobster will eat its old shell to regain the calcium . while the animals molt , they are extremely vulnerable to predation , but this is also the only time that females can be mated .
because the atlantic slipper shells are capable of changing sexes when necessary , the bottom shell in these stacks of shells is female and the top shells are male . the top shells directly fertilize this female at the bottom by sending down an extension to the female with sperm to fertilize the eggs . the larvae then sink to a point where they attach to more stacks of slipper shells , or they attach on their own to something else . if they attach to another stack of slipper shells , it remains a male . if it attaches on its own , it switches to a female , and tries to attract male slipper shells by secreting a chemical which does just that ( lilley ) . another interesting fact is that when the bottom female slipper dies , the next slipper shell up which is male , becomes female and this pattern is continued . because the slipper shells are capable of changing sexes , there will always be an efficient ratio of males to females for reproduction .

unlike limpets , slipper shells are sedentary . once the planktonic larvae settle on a suitable spot in the intertidal , the young slipper shell remains there , sculpting its shell to match the surface of the rock so that it can suction cup itself in place ( a good reason to not pry these snails off of rocks — they won’t be able to reattach ) . because it stays put ( the scientific word for this is sessile ) , slipper shells cannot graze upon algae or hunt for prey like other snails . it is a filter feeder . like a clam or mussel , it pulls water into its mantle cavity ( inside the shell ) and any plankton in the water stick to the gills and are transferred to its mouth .
slipper lobster fisheries are characterized by a lack of fisheries management oversight , which can lead to overfishing and rapid depletion of the resource . this is exacerbated by a lack of data on nearly every aspect of slipper lobster fisheries ( catch , size , seasonal trends ) . because slipper lobster is primarily landed by bottom trawls , habitat impacts are also a potential issue .
slipper shell snails begin as males but later transform to females , so each individual is a sequential hermaphrodite . eggs are fertilized internally . females release thousands of microscopic swimming larvae ( veligers ) , which disperse and later metamorphose on the ocean floor .
short description shell moderately convex , ovate , rather thin , with apex at posterior margin , slighly curled dextrally . outer surface smooth or with only growth lines . inside with a septum which occupies the posterior half . edge of shell thin and cutting .
the slipper limpet is tolerant of a wide range of temperature conditions through all life stages and can survive low water quality .
the slipper meat is processed from the pink - shelled tail and is especially suitable for broiled open - faced style sandwiches .
the plate or partition often has a reddish - brown edge . the plate , or as it has been called , “the deck , ” is typically concave with a sinuate or wavy edge . the outer surface of the gastropod may be either smooth or wrinkled . the common atlantic slipper shell is yellow , creamy , or brownish , often flecked with reddish brown , and can be found from canada to texas , and on northwest european shores . the living gastropod inhabits shallow water . the shell grows up to a length of 1½ inches . there is no operculum .

because of an editing error , the cancale journal article last wednesday , about efforts by a french businessman to coax fishermen as well as municipalities in the brittany region of france to sell an invasive species of sea snail , the atlantic slipper shell , for consumption misattributed a quotation about the shell . it was frederic baslé , the owner of a seafood cart at port de la houle — not pierrick clément , a local food entrepreneur who has been promoting the shellfish — who said , “the shell is just not that pretty . ”
crepidula atrasolea ( formerly c . cf . plana ) can be distinguished from other crepidula species by the following suite of characters . the flat white shell ranges from recurved to somewhat convex depending on the habitat of the individual . animals from exposed substrates are often oval and convex with a more robust shell . the shelf is flat in convex shells and convex in recurved shells , with a notch on the right side where it attaches to the shell and also a depression in the center of the shelf margin . muscle scars are absent . apex at the shell margin usually directly posterior , sometimes slightly recurved to the right . the shell is white , inside and out .
likely to be preyed upon by certain species of crab , bird predatory starfish and predatory snails . although experiments have shown the common shore crab ( carcinus maenus ) and the starfish ( asterias rubens ) prefer to feed on native mussels . slipper limpets are also preyed on by the invasive american oyster drill ( urosalpinx cinerea ) .
this species is common on rocks , shells , and pilings in protected bays , but it also lives in sheltered places on the open coast , occurring from the low intertidal zone to subtidal waters .
the slipper lobster fisheries of thailand , taiwan , china , and vietnam are largely characterized by a lack of information and resource management . sources indicate that slipper lobster is landed primarily by trawls targeting multiple species , which may contribute to the difficulty in collecting accurate data on slipper lobster landings . because of the multi - species nature of the trawl fisheries that land slipper lobster , bycatch , particularly of juvenile finfish species , may be an issue . although slipper lobster reside in somewhat more resilient habitats ( e . g . , sand and mud ) , fisheries that land these lobsters may also take place over more structured habitat , where bottom trawling could negatively impact the sea floor . in order to mitigate environmental risk factors from trawl - caught slipper lobster , the use of traps should be encouraged .

shell collecting has been a popular hobby for about 200 years , and the most attractive and valuable shells are those of snails . visitors to the beaches of southwest florida can hardly avoid becoming collectors , the shells are so varied and abundant . malacologists have mixed feelings about shell collecting . no matter how rare or how beautiful , a shell that lacks a label specifying date , place , conditions , and name of collector is scientifically worthless .
jingle shells ( anomia simplex ) are an organism that attaches to something hard , like wood , a shell , a rock or a boat . they are sometimes mistaken for slipper shells , which also attach to a hard substrate . however , slipper shells have only one shell ( also called a valve ) , while jingle shells have two . this makes them bivalves , which means they are related to other two - shelled animals such as mussels , clams , and scallops . the shells of this organism are very thin , almost translucent . however , they are very strong .

the exterior of the shell is dull white or cream with wavy longitudinal lines of a light chestnut color . the interior is a shiny light brown .
the way in which the atlantic slipper shells reproduce is quite extraordinary and efficient . they do mate directly as opposed to sending sperm and eggs into the water and hoping for a connection . atlantic slipper shells tend to pile up , one on top of another and can make stacks of multiple shells .

a very tasty and extremely rare type of crustacean , particularly appreciated in italy , is the cicala grande di mare ( scyllarus latus ) , also known as magnosa . it is so rare that there is not even a common name for it in english , but ‘mediterranean slipper lobster ‘ would be the closest denomination . it is very rare because it is very sensitive to pollution .
in the slipper - shell snails ( crepidula ) , which are rather sessile , all the young are males ; their subsequent sex , however , is determined by their nearest neighbour . they remain males as long as they are near a female but change into females if isolated or placed near another male . …
crepidula fornicata may compete with oysters for food and attachment sites in oyster reefs . however , quantities of the shell have been used commercially as an underwater foundation on which oyster embryos can grow . in a splendid work , the shell book , written by julia e . rogers in 1931 , the authoress tells us :
if you look out on the sand flats you will find thousands of live slipper shells . if you look closely you will notice that they occur in a stack of 2 - 5 individuals , usually , with the bottom one attached to a small rock . the stacks tell you much about their life history . the bottom individual is larger than the ones at the top of the stack and is inevitably a female , but the top individuals are smaller and males . what is not obvious , is that every individual common slipper shell starts life out as an immature snail , then matures into a male , then loses the male function and matures into a female ! if a new slipper shell comes on top of the first and lowest animal in the stack , it will have male function ( copulation occurs by means of a penis ) , until another individual comes on top of him . he will then change sex to female function . sex change , therefore , is not precisely timed but depends on the presence of other individuals in the stack .
spiny lobsters such as the california spiny lobster and the caribbean spiny lobster lack large pinching claws , and as a result they are sometimes called crayfish . however , these common names can lead to some confusion , as freshwater crayfish do possess claws .
since adult slipper shells cannot move around , they need to live close together in order to mate . when the planktonic larvae settle to the bottom , they like to settle on top of other slipper shells and form vertical stacks with the largest and oldest on the bottom . here’s where their sex life gets interesting . slipper shells are protandrous hermaphrodites , meaning they always start out male , and given the right conditions become female as they mature ( they’d be protogynous if they were female first ) . so , when the planktonic larva settles down on a substrate , it is male and stays male until some signal tells it to become female . if it is the only slipper shell around , it will develop into a female and send out chemical signals to attract other slipper shells to come settle on her , forming a stack of slipper shells with the oldest female on the bottom and younger males on top of it . think about this . the males are able to directly fertilize the female beneath , even if separated by four or five other males ! when i first learned this , it was in conjunction with the provocative scientific name , crepidula fornicata .
mr . clément aims to sell the slipper shells primarily to the american , japanese and chinese markets , where they might have a less pesky reputation than in france .

snails have occupied practically every type of habitat that supports animal life . dehydration appears to be the greatest danger for terrestrial snails , while predation is the greatest danger for marine snails . bieler has estimated that 53 % of all snail species are prosobranchs , largely marine , 4 % opisthobranchs , entirely marine , and the remaining 43 % pulmonates , terrestrial and freshwater . in intertidal zones , numbers of prosobranchs such as the common periwinkle littorina littorea seem as uncountable as stars in the sky . according to abbott , littorina probably reached north america from europe on driftwood
before the time of the vikings
( about a . d . 1000 ) and gradually extended its range from newfoundland to ocean city , maryland . in exchange , about 100 years ago we gave northern europe the common slipper shell crepidula fornicata , which has proliferated to the point of being a pest of english oyster beds .
at least some members of this species have ripe gonads throughout the year in oregon and california . in california they appear to spawn multiple times a year but only once in oregon ( late summer or fall ) . the most exposed sites are dominated by mature individuals while juveniles are more common in protected sites . lifespan is 5 - 8 years in the southern part of the range but up to 30 years farther north . egg production also seems to be greater in populations farther north , and larger individuals are more common there .
the bodies of the reclusive slipper lobsters are more heavily armored than spiny lobsters and they are sometimes described as looking like a flattened armadillo . slipper lobsters do not have the long antennae found in spiny and american lobsters . instead their antennae have been modified into large flattened plates at the front of the body . not highly sought - after as food sources by fishermen or divers but a delight for the eyes of divers , especially underwater photographers , a variety of species of slipper lobsters occur in tropical and semitropical seas around the world .

( 1998 ) and cole & hancock ( 1956 ) reported dredging operations to clear slipper limpets from oyster beds , but concluded that further spread of the species could not be prevented .
sea port has initiated tracing requirements from their slipper lobster suppliers that will start to pinpoint the vessel name ( when available ) that caught the slipper lobster , the catch method and the catch area . collection of such data may help spur the eventual establishment of management schemes for this multi - species trawl fishery and also to encourage the greater use of traps . sea port believes that , in aggregate , choosing from a diverse variety of seafood is better for sustaining the world’s seafood resources and that slipper lobster should be a part of this variety .
. the foot is usually rather large and is typically used for crawling . it can be modified for burrowing , leaping ( as in conchs , strombidae ) , swimming , or clamping ( as in limpets ) . the foot typically bears an operculum that seals the shell opening ( aperture ) when the head - foot is retracted into the shell ( see photos below ) . while this structure is present in all gastropod veliger larvae , it is absent in the embryos of some direct developing taxa and in the juveniles and adults of many heterobranchs . the nervous and circulatory systems are well developed with the concentration of nerve ganglia being a common evolutionary theme .
the slipper shell , which can be considered a vital part of the ecology in certain areas , is also considered a problem in others . they are very efficient when it comes to feeding and reproducing , which makes them so abundant around the world in the oceans . there is not much potential for the population of these organisms to atrophy considering they have no significant predators .

while the body color of spiny lobsters ranges from reddish to blue to bluish - black , american lobsters are typically olive green to greenish brown , but specimens that are orange and even bright blue do occur . diet , genetic makeup and exposure to sunlight combine to determine their color . however , when you see a cooked america lobster the shell is usually bright red . this is because the major pigment in the shell , astaxanthin , usually appears to be greenish or bluish when bound to proteins in the shell . heat frees those bonds , and the natural color of unbonded astaxanthin is red .
mr . clément grew up dive - fishing for oysters , abalones and sea urchins , and , like most bretons , he had never thought of eating the ubiquitous atlantic slipper shell . then he found out about a mechanism that could crack open the shells of the invasive sea snails on an industrial scale without damaging the flesh , and he quickly invested a million euros in research and development .

the slipper limpet has been introduced into numerous locations around europe and on the western coast of america . it is thought to have been introduced into the solent in the 1930s and by the 1970s , was thought to be the most dominant seabed creature in the area . by the 1960s , the population had spread to start point devon and the species is currently common along the entire southern coast of england . this rapid domination and spread has been mirrored in suitable habitats elsewhere around europe .

a loss of amenity value caused by slipper limpet infestation may occur . in addition , traditional fishing practices may be affected and in areas heavily dependant on fishing , these social impacts may be serious .
even worse for a fruit de mer — a french term that designates all edible seafaring creatures besides fish — “the shell is just not that pretty , ” said mr . baslé , the seafood cart owner .
jean - françois dore raked up the atlantic slipper shells that cover the seabed in the waters off cancale in france in an attempt to protect the area’s oyster and mussel farms from the invasive sea snails .
eventually he hopes to process as much as 100 , 000 tons of slipper shells per year — enough to offset their growth in the bays of mont saint - michel , saint - brieuc and morlaix .

telline ( donax trunculus ) used to be so common that you could see bathers in the early morning , when the sea was calm , walking in the shallow waters in front of sandy beaches picking them with their bare hands or with special scoop nets . while the latter is still a common practice among fishermen and people of the older generation , telline have become a little harder to find , especially close to the shore . human intervention along the coast line have pushed the natural habitat of this mollusc further away from the shore , but in fish shops they are still widely available , even if on an irregular basis .
if you find a thin , shiny shell while walking on the beach , it might be a jingle shell . jingle shells are shiny mollusks that got their name because they produce a bell - like sound when several shells are shaken together . these shells are also called mermaid ' s toenails , neptune ' s toenails , toenail shells , gold shells and saddle oysters . they may wash up in large numbers on beaches after storms .
crepidula atrasolea prefers epibenthic habitats in shallow oyster reefs , often near mangroves . it is most common intertidally to subtidally , but prefers slow moving waters with with low wave exposure . typical maximum water depth is to at least 20m , in the florida keys , it is commonly found subtidally in shells inhabited by hermit crabs .

california divers periodically encounter two species of crustaceans that are commonly known as squat lobsters . while these animals bear some resemblance to lobsters , scientists point out that they are actually more closely related to their crustacean cousins , the hermit crabs . one species of squat lobster is also known by the common names tuna crab and red crab .
notice that in english tellina refers to a genus of shells , whereas in italian it is a specific type of shell , the donax trunculus , which , as the name indicates , belongs to a different genus , the donax .
because quán ốc are such informal and open spaces , there’s a constant buzz of vendors ( often older women ) who walk from table to table offering diners the perfect snacks to go with their ‘shell tapas’ . popular ones include :

slipper lobsters , also called flat , locust , spanish , shovel - nosed and bulldozer ; australians call some of them “bugs ; ” are scattered throughout many of the world’s warmer coastal waters , but nowhere in large quantities .
the company has developed a patented cold shelling process for slipper limpets , an invasive shellfish found on the coasts of normandy and brittany , to add value to the flesh and shell . the increased capital will enable the company to move on from the pilot stage to industrialisation . work is currently underway in the processing plant to create a capacity of 20 tonnes / day by september . five new jobs are scheduled before the end of the year as a result of this upscaling . the company works on a cooperative basis with the regional shellfish committee of northern brittany ( comité régional conchylicole bretagne nord ) , which purchased the first vessel to specialise in the harvesting of slipper limpets in 2013 .
joseph jambon , head of the local shellfish producers union , has agreed to share his oyster fishing boat le papy with mr . clément , who declared it the first boat in the world to willingly fish for atlantic slipper shells .
“everyone wants to get the most out of their space , ” said mr . jambon . but “what’s important , ” he added , is that the slipper shells “scram and that we promote it and that our production improves . ”
has been introduced to the west coast of the united states , the coastal waters of asia , and the coastal waters of england , france , and other european countries . in these locations , slipper shells have become a nuisance in
slipper lobster tails and meat should be thawed in a sealed plastic container or bag and placed under refrigeration ( 33 - 39°f ) for 12 - 24 hours or until completely thawed . this thawing method produces a high quality product . to quick thaw , place the product in a colander and run under cold water for 4 - 8 minutes or until completely thawed . thawed slipper lobster should be held at 33 - 39°f and totally consumed within 2 - 3 days .
the slipper shells have been prevalent in brittany since the 1970s and were brought here by ships carrying oysters , though local lore has it they were first brought to nearby normandy in 1944 , stuck to the hulls of british allied ships .

the larvae feed on opuntia lindheimeri var . lindheimeri .

young larvae hollow out a small cell under the epidermis near the margin of the cladode .

they remain in this cell during winter .

in april , they tunnel farther into the cladode .

pupation takes place in late august and september within hollow stems of their host plant .

melitara texana

melitara texana neunzig , 1997 n . sp . , mona fascicle . 15 . 4 .
melitara texana is a species of snout moth in the genus melitara . it was described by neunzig in 1997 , and is found in southern texas and adjacent mexico .
home » guide » arthropods ( arthropoda ) » hexapods ( hexapoda ) » insects ( insecta ) » butterflies and moths ( lepidoptera ) » pyralid and crambid snout moths ( pyraloidea ) » pyralid moths ( pyralidae ) » phycitinae » phycitini » pricklypear borer ( melitara ) » melitara texana - hodges # 5971 . 2 ( melitara texana )
the destruction of so many prickly pears has spurred me to action . no , i am not going to spray chemicals to save the cactuses . but i have collected a few larvae with the intent to rear them and determine , if i can , the identity of the moth . in a quick search of the web to determine the identity of the caterpillars , i found that there are at least six prickly pear borer moths , including melitara prodenialis and melitara dentata that are native to several states in the united states . neither of these two moths along with melitara texana have been documented in texas . i could find no images of melitara texana or its larvae .
moved from moths . ann , these are very closely related to alberada . i get m . texana and there is m . dentata from n . and western tx . i need to check collection records to see which you get . they are determined by genitalia and range .
moved from melitara dentata . after revisiting my bold results this may be m . doddalis . although my results came back 100 % m . dentata , bold did not make a species choice and my coi was only 586 . there is a lot of m . dentata dna available but all of it was from canada and mine were the only ones from texas . there is only one bold tested m . doddalis ( coi 658 ) and was from uvalde and looks similar to mine . several bold identified m . doddalis were from texas but did not have dna .

well , they are back and up to their old tricks . this time i intend to find out the name of the rascals and add it to the official list of residents or visitors in kendall county . to borrow and paraphrase a few of the lines from that doc watson song “muskrat , … they have been lying around eating up all the owners’ prickly pear… but i found out where they been usin’” .
when we moved to boerne a few years ago , the small acreage where we built our home had several large prickly pear cactus plants at various locations . the plants were 3 - 4 feet tall and up to 5 feet across . each spring i enjoyed seeing the variety colors that they produced . some had beautiful , deep peach blooms , some had yellow blooms with red centers and some blooms were entirely yellow .
two years ago i noticed that there was a sawdust - like substance on some of the pads of a few plants . i broke off one of the tops and saw a few larvae in the stem . i assumed that this was just another example of a moth and a host plant and didn’t pursue it more than taking a few pictures .
now there are only two or three of those large plants left . the others , including many on adjoining lots , have been decimated by those moths , which deposit their eggs on the prickly pear . when the larvae eclose ( emerge from the eggs ) , they eat the interior of the pads and excrete their frass ( poop ) through small holes in the pads leaving a sawdust - like residue . all that remains of those large cactus plants are the skeletal veins of the pads and stems , decaying like fallen logs
surely i am not the only person in texas that has lost and regretted the loss of a prickly pear , our state cactus . i can only assume that when others lost that plant , they just decided it was easier to get another . but i am now about naming the culprit . i want to make sure that this moth is listed as being present in texas and in kendall county . i will bring you a report if i am successful .
even so all is not lost . the native plants that grow in our area are survivors . so far each has changed to meet every challenge that the climate , insects and the environment have provided . i have no doubt that the prickly pears will overcome the attack of the moths . in some of those piles of debris , small green pads are visible . it will take a few years , but hopefully those beautiful blooms will return .
on a more pleasant subject , a couple of weeks ago , i had the opportunity to join donna taylor , patty leslie pasztor and an out of town botanist on a ride through a small portion of the 500 plus acres of the cibolo preserve . as you probably know the cibolo preserve is adjacent to the cibolo nature center and has been set aside by its owner , bill lende , for restoration , research , education and conservation . what a pleasure it was to take that ride .
even though we are entering the month of august in a continuing period of drought , albeit with some late spring rain , the condition of the land was spectacular . grasses of all kinds was at least knee high . the big bluestem , vigorous and in bloom , was 5 ½ to 6 feet tall . the fields were filled with butterflies ; and ducks rose from the creek as we crossed . a night heron flew into a tree from its hunting spot along the creek and flew to the same tree when we returned along the same route . hawks were circling in the sky .
plants that have passed their bloom time along the county roads were still in bloom in the fields . a skeleton plant , still producing nectar , was visited by a pipevine swallowtail butterfly and narrowly avoided my camera lens . ( ernesto has skeleton plants for sale at medina garden nursery in medina , if you are interested ) .
although native plants have evolved to survive nature’s challenges , loss of habitat , which is mainly our doing , may prove a hill too high . it is a pleasure to see what bill has accomplished with this vision of the past and oasis of hope .

the square-tailed drongo-cuckoo ( surniculus lugubris ) is a species of cuckoo that resembles a black drongo .

it is found in sri lanka and southeast asia and is a summer visitor to the himalayas from kashmir to eastern bangladesh .

the calls are series of piercing sharp whistles rising in pitch but shrill and choppily delivered .

square - tailed drongo - cuckoo

square - tailed drongo - cuckoo ( surniculus lugubris ) is a species of bird in the cuculidae family .
these square - tailed drongo - cuckoo species have moderate forest dependence . these species occur in altitudes from 0 to 2100 meters . the artificial ecosystems of these square - tailed cuckoo species include rural gardens and urban parks .
( a square - tailed drongo - cuckoo chick being fed by an olive - winged bulbul . photographed by johnny chew at panti , malaysia in july 2010 )
from the above photos , the differences are quite easy to pick out . first look , the square - tailed drongo cuckoo has a slimmer look giving it a longish appearance . the crow - billed drongo looks broader .

it was a rainy day . asian drongo - cuckoo calling constantly from early morning . we also heard distant answering call from another asian drongo - cuckoo . later other birders informs us , pair of asian drongo - cuckoo did mating there .
these square - tailed drongo - cuckoo species are distributed in india , bhutan , bangladesh , myanmar , thailand , malaysia , singapore , brunei , indonesia and philippines . unconfirmed reports of their sightings were recorded from nepal .
the square - tailed drongo - cuckoo species are distributed in india , bhutan , bangladesh , myanmar , thailand , malaysia , singapore , brunei , indonesia and philippines . these cuckoo species resemble black drongos . there are two recognized subspecies of these cuckoos .
some recent work suggested that the species was conspecific with the fork - tailed drongo - cuckoo and together known as the asian drongo - cuckoo , but should be split based on call and morphological differences : . that treatment is taken here .
the overall plumage of these square - tailed drongo - cuckoo species is glossy blue - black in adult birds . the wing - coverts , inner secondaries and tertials are black with greenish tinge . the underparts are blackish with brownish tinge .
the breeding season of these square - tailed drongo - cuckoo species is from april to july in northeast india . the laying season is from may to july in malay peninsula . the breeding season is during april and may in indonesia .
the vent region and undertail have slight white barring . the tail is long and square . there are white specks on the tip of tail feathers . the bill is black and straight . the irises are black . the feet are dark gray . the square - tailed drongo cuckoo call is a loud , piercing sharp whistling sound .
the iucn ( international union for conservation of nature ) has categorized and evaluated the cuckoo species and has listed it as of
least concern
. the cites ( convention on international trade in endangered species of wild fauna and flora ) status is ‘not evaluated’ for the square - tailed drongo - cuckoo (
( a young square - tailed drongo - cuckoo being fed by a pin - striped tit - babbler . this record is from hulu langat , malaysia and was photographed by christopher lee in may 2010 . we have other records of this host species at macritchie reservoir previously )
the diet of these square - tailed drongo - cuckoo species is mostly insects . caterpillars , beetles , swarming termites and ants , spiders , grasshoppers , cicadas , and locust are their primary food . they are mostly arboreal . they glean the prey from foliage or the ground .
the last feature is the shape of the tail . the cuckoo has more or less a square tail sharing the characteristics of all cuckoos while the drongo has a forked tail flaring outwards quite a bit .
only the underside of the tail of the cuckoo has scattered white barrings on it like most cuckoo species while the tail of the drongo i s unmarked .
it is not often that two species from different families can be confusing . more so when they share the same common name as in the case of the crow - billed drongo dicrurus annectans and the squared - tailed drongo cuckoo surniculus lugubris . both are black and have more or less the same structure as each other . but look closer and you will find distinctive features in each species to tell them apart . the crow - billed drongo is a winter visitor and passage migrant to singapore while the st drongo cuckoo is a breeding resident with a few visiting during the winter months . if you see one during the summer months , it will be the squared - tailed drongo cuckoo . they are very vocal all over our forests in may during breeding .
these square - tailed cuckoos are brood parasites , laying eggs in the nest of other birds and rely on the host to raise their young . the breeding season coincides with breeding season of the local host species .
summer breeding populations of these drongo cuckoo species are found in bhutan , northeast india , bangladesh and east myanmar . they migrate to southeast asian countries for wintering .
the bill of the cuckoo is thinner and slightly decurved , typical of all cuckoos , while the drongo has an unmistakable broad bill from whence its name is derived .
rusty - breasted cuckoo the rusty - breasted cuckoo ( cacomantis sepulcralis ) is another uncommon resident in singapore . the female and young of the species is often confused with the plaintive cuckoo and the quickest way to sepoarate this two species is to look for the yellow eye - ring that is present in this species , but not the plaintive cuckoo . the local host for this species is the malaysian pied fantail .
violet cuckoo the last cuckoo in the roundup is the violet cuckoo ( chrysococcyx xanthorhynchus ) , probably the rarest resident cuckoo in singapore . it’s host species include the brown - throated sunbird , van hasselt’s sunbird and the olive - backed sunbird . unfortunately we could not obtain any local photos of these although we had sightings records in the past . perhaps the cuckoo’s rarity does not permit an easier encounter . looking through the internet we do have a photograph of a brown - throated sunbird feeding a chick from sabah that can be found here : urltoken
little bronze cuckoo the little bronze cuckoo ( chrysococcyx minutillus ) a common resident cuckoo species that is easily found in the various nature parks and gardens . interestingly before 1964 , they were not recorded in singapore . there are two host species historically recorded , the golden - bellied gerygone and the olive - backed sunbird ( 2008 ) .
a first winter crow - billed drongo on passage was photographed at bidadari on the 19th of september by lim ser chai . this is the first arrival for this season but stayed for less than 2 days .
in india , these cuckoo species are distributed in the states of assam , arunachal pradesh , meghalaya , tripura and mizoram .
) is a small cuckoo , measuring 25 cm in length and weighing 25 to 45 grams . both the sexes look alike .
( a plaintive cuckoo chick being fed by a ashy tailorbird . photographed at pasir ris park by johnson sia in september 2014 )
( a banded bay cuckoo chick being fed by a common iora . photographed by francis yap at lorong halus in may 2011 )
the populations of these cuckoo species in southern myanmar , eastern and southern thailand , malaysia , singapore , indonesia and philippines are resident birds .
( a golden - bellied gerygone passing food to a recently fledged little bronze cuckoo . photographed by francis yap at pasir ris park in august 2011 )
banded bay cuckoo rounding up the resident cacomantis cuckoos is the locally uncommon banded bay cuckoo ( cacomantis sonneratii ) . unlike the other two species where the appearance of the male and the female differ ( sexual dimorphism ) , both the sexes of this species are alike . the host of this species is the common iora .
( a rusty - breasted cuckoo chick post - feeding with its surrogate parent , the malaysian pied fantail . photographed by francis yap at lorong halus in august 2012 )
plaintive cuckoo the plaintive cuckoo ( cacomantis merulinus ) is a more uncommon resident cuckoo species . it is named for the plaintive call of the male in mating season . in the past , the british colonial birders referred to it as the malayan brain fever bird due to its call and the malay called it burung mati anak ( bird whose child died ) , such is the emotional intensity that it elicits . this species local host is reported to be the common iora but recent photographic report was with the ashy tailorbird .
normally one egg is laid in the nests of host species . in india , the hosts are small babblers . the cuckoo hatchling may heave out other eggs and nestlings of the host .
) does not approach the thresholds for being vulnerable , either under the range size criterion , or under the population trend criterion , or under the population size criterion . the ongoing habitat destruction is the main threat that may endanger the survival of these cuckoo species .
( the video shows the behaviour of the chick in the presence of the the host parent , where the combination of call , wing flapping position and opened mouth with prominent gape all direct the iora with food to the cuckoo . this was taken at lorong halus in june 2011 )
the cuckoos are well known examples of brood parasites , birds that lay their eggs in the nest of of another bird species and relying on their host to raise the young . not all species of cuckoos do that however . in the local context , we have the malkohas and coucals that raise their young on their own , yet are part of the cuckoo family .
the most famous resident cuckoo is the asian koel , that is the source of most number of complaint from the public due to its noisy nature . it is known to use the crows and mynas as surrogate parents elsewhere . the house crow is listed as the most common surrogate host for the koel in singapore . however , less work and documentation exist for this host - brood parasite interaction even though these two species are a common sight . this is because crow nests are normally destroyed on sight as they are considered a pest species .
