snail is a common name loosely applied to shelled gastropods .

the name is most often applied to land snails , terrestrial pulmonate gastropod molluscs .

however , the common name snail is also used for most of the members of the molluscan class gastropoda that have a coiled shell that is large enough for the animal to retract completely into .

when the word " snail " is used in this most general sense , it includes not just land snails but also numerous species of sea snails and freshwater snails .

gastropods that naturally lack a shell , or have only an internal shell , are mostly called slugs , and land snails that have only a very small shell ( that they can not retract into ) are often called semi-slugs .

snails have considerable human relevance , including as food items , as pests , as vectors of disease , and their shells are used as decorative objects and are incorporated into jewelry .

the snail has also had some cultural significance , and has even been used as a metaphor .

the ancient aztecs of mesoamerica saw the snail as a sacred being in that its shell represented the cycle of life . this belief is supported by artwork , paintings , drawings , and carvings in ancient places that include the spiral shell of the snail . the snail ' s shell can also be seen carried on the god tecciztecatl ' s back . tecciztecatl was a lunar deity ( a god of the moon ) , and he carried a shell on his back because the aztecs associated the snail with the moon . just as the snail retreats into its shell , the moon retreats into the depths of the ocean .
in the picture below , you can see the panthers are holding the spiral snail shell and using it as a horn .
another signaling pathway that has been related to snail expression is that requiring pi3k activation . our results do not suggest a major involvement of this pathway in the activation of snail transcription in most of the tumor cell lines , but we cannot discard that it might contribute to snail expression in some cell lines , since in some cell lines ( iec - ilk , scc15 - akt ) additional sequences other that those present in the minimal promoter seem to be necessary for the full stimulation of snail promoter .

snail superfamily members function as transcriptional repressors ( 16 , 29 ) . transcriptional repression function is associated with various conserved protein domains . in vertebrates , the snag domain is essential to transcriptional repression function of snail family members . drosophila snail lacks the snag domain , yet it still functions as a transcriptional repressor , through interaction with a well - characterized corepressor , ctbp ( 16 , 29 ) . consensus sequences for interaction with ctbp are found in some , but not all , members of the snail superfamily ( 29 ) .
additionally , nodal expression in chick embryos is not affected by high levels of snail anti - sense oligonucleotides [ 8 ] . our finding that cryptic , a co - receptor for nodal signals , is repressed by snail now provides a plausible mechanism behind this observation . in the absence of snail , freely transcribed cryptic causes propagation of nodal signals by acting as its co - receptor . with this mechanism in action , addition of high levels of snail anti - sense oligonucleotides will have no effect on nodal ( as shown in this report ) because cryptic repression is already withdrawn . on the contrary , it is likely that high expression of snail suppresses nodal signalling .
let ' s learn a little about the humble snail and it ' s history as we look through the ages passed . while the snail might be considered a nuisance in modern times to those who don ' t pay attention , there are those of us who are ready to learn of the snail ' s deep spiritual symbolism and beginnings and how these can be applied to our lives today .

please sir , i want to start the farm . how can i get the snail from you and get more directions from you .
please , sir . i want to venture into the business if snail farm . i needest species of snail . i am from the eastern part of nigeria . can i get the best species from you , i will like to by about 4 - 5 hundreds piece
the shell of my land snail is turning white . what is the cause for the change in color and what should i do ?
i learned a lot from wikihow , most especially feeding and sources of calcium . i am into snail farming . thanks .
i wanted to take care of a land snail and i kept it alive for a few months after following these tips .
there are thought to be up to 30 small snail farms in development in ireland at the moment , with about six operating commercially .
so other than the symbolic observations already made , how did the snail earn all these great features ? - mostly from cultural observations .
it’s a little guy , about an inch long , with muddy markings and a spiral shell . is this the mighty threat that’s causing all the commotion ? actually , no . the well - meaning citizen has found a rosy wolf snail , similar in appearance but without the devastating appetites of an african land snail . this spring , a rosy wolf snail was misidentified in houston , rippling panic throughout texas .
it had been a timeless love story . a garden snail with a rare genetic condition can ' t mate with normal snails ; scientists launch an international search for a mate ; the snail becomes a media sensation ; and miraculously not one but two possible mates are found .

we loved watching the world championship snail race . we learned that snails have shells and slugs do not . we also learned that slugs can go into places that snails can not . we wondered where the snail ' s eyes are located ? we will be on spring break next week and are wondering how many friends from our class will stop by and leave some comments . have a snail - rific friday !

i ' m with a bunch of treatment kids , and they are really inspired by snails . they are intrigued with snail habits ,
it might not be to everyone’s taste , but snail meat , containing protein , iron and omega - 3 , is considered a healthy food – as long as you don’t drown it in garlic butter . milka also points to the potential for production of high value snail caviar .

given the function of snail and of slug as transcriptional repressors , their ability to interfere with the apoptotic program is predicted to result from alterations in gene expression . since the tumor suppressor p53 plays an integral role in cellular responses to dna damage , the role of snail and slug in p53 regulation was investigated . expression of either snail or slug resulted in modest downregulation of steady - state levels of p53 mrna ( fig .
snail mucin is found in products such as moisturizers , serums and spot treatments . in some cases , brands use snail secretion filtrate in their products , but don ' t advertise it openly because of the ' ick ' factor . now that so many people in the west are opening up to the thought of snail mucin in their beauty products however , brands are highlighting it as an integral part of their formula .
snails need a lot of calcium in order to keep their shells healthy . a great option is a cuttlebone because you can simply break off pieces and place them in the tank for your snail to nibble on . other calcium sources should be crushed and added to your snail’s food .
i always say big meanings come in little packages . the depth of symbolic snail meaning is surprising and revealing . these little creatures represent things like : sensitivity , self - reliance , healing , patience and more ! read this article for awesome lessons the snail offers us every day .

snail and cryptic are essential for left right asymmetry in mammals . in present study we demonstrated that over expression of snail suppresses cryptic expression in transdifferentiated panc1 cells . through promoter binding studies and luciferase assays we confirmed that snail directly binds to cryptic gene promoter and regulates its expression . our study has implications in the establishment of the left - right axis asymmetry where the gene - regulatory mechanism described in this report may be utilized .
cryptic promoter activity in cells over expressing snail . plasmid construct expressing snail was transfected in increasing concentrations ( as indicated ) in hek 293 cells along with reporter constructs for cryptic promoter activity by cloning the cryptic promoter region upstream of the firefly luciferase gene . ( a ) the full length cryptic promoter , ( b ) promoter region containing a single snail binding element ( sbe1 ) , and ( c ) deleted snail binding elements are co - expressed with increasing concentrations of the vector expressing snail . ( d ) luciferase acivity is also measured for the cryptic promoter construct either containing sbei or sbeii mutant or full - length and for the vector alone . empty reporter vector is used as vector control , pcdna3 is used as control for snail transfection and beta - galactosidase construct is utilized to ensure equal transfection . the relative luciferase activity is plotted as a function of increasing snail expression . experiments are carried out in triplicates and repeated at least 3 times . data with p < 0 . 05 is considered significant

the pygmy eagle or new guinea hawk-eagle ( hieraaetus weiskei ) is a bird of prey in the accipitridae family .

it is found in new guinea .

its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests .

it is often considered a subspecies of the little eagle , but some taxonomists separate it into a distinct species .

pygmy eagle

an active nest of the pygmy eagle hieraaetus weiskei is described , providing the first documented observation of a downy chick in late january and hence an indicative laying date of late november / early december . the first documented record of this species for waigeo island ( west papua province ) is presented . a prey item being carried by another pygmy eagle is identified as a probable brown ( slender - billed ) cuckoo - dove macropygia amboinensis , and another pygmy eagle had fed upon a mountain fruit - dove ptilinopus bellus .

this species has a very large range , and hence does not approach the thresholds for vulnerable under the range size criterion ( extent of occurrence < 20 , 000 km2 combined with a declining or fluctuating range size , habitat extent / quality , or population size and a small number of locations or severe fragmentation ) . despite the fact that the population trend appears to be decreasing , the decline is not believed to be sufficiently rapid to approach the thresholds for vulnerable under the population trend criterion ( > 30 % decline over ten years or three generations ) . the population size has not been quantified , but it is not believed to approach the thresholds for vulnerable under the population size criterion ( < 10 , 000 mature individuals with a continuing decline estimated to be > 10 % in ten years or three generations , or with a specified population structure ) . for these reasons the species is evaluated as least concern .

astacoides caldwelli is a species of crustacean in family parastacidae .

it is endemic to madagascar .

a. caldwelli is mostly found in rivers draining forested areas at elevations between 600 - 800m .

the populations are threatened by habitate loss as well as predation by introduced species and harvesting at a subsistence level from local fishermen .

astacoides caldwelli

here ' s a compilation of some pics i took of what probably is astacoides betsileonensis .

astacoides caldwelli is only found in large rivers draining forested catchments , mainly on the eastern side of the escarpment ( jones et al . 2007 ) . most localities where this species is known from are in relatively recently deforested areas abutting natural forest ( jones et al . 2007 ) . astacoides caldwelli is a tertiary burrower ( jones et al . 2007 ) meaning it creates a burrow but spends the majority of its time in the water . eggs are laid in june or july and carried for approximately four months , hatching in october or november ( jones et al . 2007 ) .
justification : astacoides caldwelli has been assessed as vulnerable under criterion b1ab ( iii ) . this species has a restricted extent of occurrence ( eoo ) of approximately 11 , 930 km² and is known from eight locations . it faces a number of threats including habitat loss due to conversion of forested land to rice paddies , harvesting as a food source , and predation pressure and competition from introduced species .
astacoides caldwelli occurs mainly in the eastern highlands of madagascar , and is largely found between the latitudes 18° to 21° s , longitudes 46° to 48° e ( hobbs 1987 ) . this is a rare species found in rivers draining forested catchments ( jones et al . 2007 ) in the antananarivo ( including mandraka , andasibe , lac mantasoa , behenjy , vakinankaratra , ambatolampy and antsampandrano ) and fianarantsoa provinces ( boyko et al . 2005 ) . this species has an estimated extent of occurrence ( eoo ) of 11 , 930 km² .

here by three more pics of crayfish from madagascar . it is not entirely clear which species these are , according to a reliabe source and friend , who kindly had a look at these photos , they may be astacoides caldwelli or possibly a smooth carapaced form of a . betsileonensis but he stresses they are difficult to determine by photo . both pictured specimens were collected in the same forest stream near fianarantsoa , at least that is what my local collector tells me . i ' ll email you more pics of crayfish from other parts of madagascar in the weeks to come . best regards olaf thank you olaf

, however there is a national law preventing the harvesting of crayfish under 10 cm total length . local rules and taboos govern harvesting in some areas ( jones
monitoring of this species ' range and abundance is required to better understand the rate at which it is being lost . however , establishing a community led monitoring program may prove difficult as it is understood that time lost monitoring is time lost harvesting ( hockley
