pyrosoma atlanticum is a pelagic species of marine colonial tunicate in the class thaliacea found in temperate waters worldwide .

the name of the genus comes from the greek words pyros meaning ' fire ' and soma meaning ' body ' , referring to the bright bioluminescence sometimes emitted .

the specific epithet atlanticum refers to the atlantic ocean , from where the first specimen of the species was collected for scientific description ; it was described in 1804 by françois péron , a french naturalist .

this bizarre and rarely - seen creature is called a pyrosome , a species of pelagic colonial tunicates . their scientific name , pyrosoma atlanticum , is derived from the greek words pyro meaning ‘fire’ and soma meaning ‘body’ which refers to the fact that they are known for bright displays of bioluminescence .
pyrosoma atlanticum are one of the few pyrosomes that make it to the west coast of the u . s . the species found here are less than a foot but can get as long as 24 inches . largely colorless , they can show up as pink , grayish or purple - green .

. . . measurements of the mesh of the pyrosome pyrosoma atlanticum [ 97 ] suggest submicron particle capture is likely ( electronic supplemen - tary material , table s2 ) . the only study to date on size selectivity of pyrosomes showed favourable selection of par - ticles greater than 10 mm [ 76 ] . the smallest cells identified in p . atlanticum faecal pellets were 3 - 5 mm phytoplankton [ 72 ] , but a recent study hypothesized that a swarm of p . spinosum was sustained by high densities of synechococcus and flagellates approximately 1 - 3 mm [ 98 ] . . . .
during the 21st cruise of r . v . gaveshani in the bay of bengal in august 1977 , a big colony of pyrosoma , about 100 cm long and 50 cm wide , was located in the surface layers of water about 320 km off kakinada . a portion of a similar colony was collected in the plankton net about 200 km south east of this station . the colony was incomplete and partly damaged due to the cyclonic weather conditions . however , the species could be identified as pyrosoma atlanticum . the earlier records and description of the species are discussed
structure and functioning of colonial pyrosomes are largely undescribed and their lipid characteristics have received limited attention . the aim of this paper is to fill this gap on one of the dominant species pyrosoma atlanticum . lipid content is tightly coupled to size and weight . lipid composition shows a large dominance of structural polar lipids . neutral lipids were dominated by sterols . . . [ show full abstract ]
pyrosoma are hermaphroditic , with each zooid producing both eggs and sperm . the fertilized egg gives rise to an embryo that develops into four attached zooids which subsequently reproduce asexually by budding off new zooids ( brooks 1906 ) . this budding process is responsible for the growth of the colony . thus , the life history of pyrosoma includes both sexual and asexual phases .
perissinotto and co - workers investigated the feeding dynamics of the pelagic tunicate pyrosoma atlanticum in the southern indian ocean . colonies showed highest retention efficiency for particles > 10 µm , and clearance rates were among the highest recorded in any zooplankton grazer ( up to 35 l h –1 per colony ) . gut pigment destruction rates exceeded those previously measured in salps and appendicularians . neutral lipid classes in p . atlanticum were very similar to those of both dinoflagellates and prymnesiophytes ; zooids contained small amounts of lipids , and low percentages of triacylglycerols and free fatty acids , which suggests that they use high biomass turnover as an alternative strategy to energy storage .
most pyrosoma species are tropical . unlike most tunicates , which are benthic ( bottom - dwelling ) and sessile ( fixed in one place ) as adults , pyrosoma are pelagic at all life history stages , floating freely in the open ocean , sometimes in enormous numbers . one recent study off the coast of west africa ( lebrato and jones 2009 ) suggests that pyrosoma tunicates that die and sink quickly to the bottom of the ocean may represent a major food resource for both benthic microbes and larger benthic organisms in the deep sea and should be included in models of large - scale cycling of elements such as carbon .
as with many gelatinous zooplankton , we lack crucial insights into their natural history . so it can be difficult to tease apart how they may be impacting marine ecosystems . for instance , pyrosomes can grow rapidly and are efficient filterers with the potential to have a significant impact on phytoplankton blooms . for now , our current observations maintain that recent oceanic conditions are ideal for pyrosome populations . i’m guaranteeing this isn’t the last you’ve heard of pyrosoma atlanticum . stay tuned !

. . . for example , gelatinous forms are often lipid poor ( e . g . 6 % dm in pyrosoma atlanticum ) and dominated by membrane polar lipids ( perissinotto et al . , 2007 ) , whereas crustaceans can be relatively lipid rich [ e . g . krill tend to have substantial lipid contents of up to 48 % dm ( hagen et al . , 2001 ) ] with potentially large proportions of neutral storage lipids ( falk - petersen et al . , 1999 ) . . . .

pyrosoma may migrate hundreds of vertical meters each day . a study of pyrosoma atlanticum occurring in offshore waters of the ligurian sea ( northwestern mediterranean ) in april of 1991 found that daytime depths and amplitudes of the diurnal migration were correlated with colony size . the amplitude of the migration ranged from 90 m for 3 - mm - length colonies to 760 m for 51 - mm - length colonies , with a mean amplitude of 410 m for the overall population pooled ( andersen and sardou 1994 ) . in the same study , the results of horizontal hauls at a given depth around sunrise and sunset revealed a marked diurnal symmetry of the migratory cycle relative to noon , and showed that migration of the population was not cohesive . for example , the larger the colonies , the later after sunset they reached the upper layers during their upward migration .
. . . the colonial pyrosome pyrosoma atlanticum filters particulates from the water column ( esnal , 1999 ) , with high retention efficiency for particles . 10 mm ( perissinotto et al . , 2007 ) , whereas the hyperiid amphipod vibilia armata is best known as a symbiotic ectoparasite of gelatinous animals ( vinogradov , 1999 ) . regional distinctions in the food environment of these species were indicated by increased levels of 18 : 2v6 , a biomarker for chlorophytes or cyanobacteria ( volkman et al . , 1998 ; gugger et al . , 2002 ) , in the northern specimens . . . .

. . . similarly , no clear daynight migration pattern was recorded in pyrosoma ( not identified to the species level ) in the open waters ( along 88°e ) of the bay of bengal ( madhupratap et al . 2003 ) , although the pyrosoma colonies there were non tubular , smaller in size ( 10 × 10 cm ) , fewer in number , and whitish in color . as pointed out by perissinotto et al . ( 2007 ) , the trophic function , feeding dynamics , as well as ecology and physiology of pyrosomes are not well known . analysis of gut contents of pyrosoma ( hart , as cited by culkin and morris 1970 ) showed that the main food was phytoplankton ( approximately 80 % ) belonging to the classes haptophyceae , chrysophyceae , and bacillariophyceae , the remainder was composed of protozoan species such as radiolarians and tintinnids . . . .
pyrosoma atlanticum like most members of the pyrosomatidae is bioluminescent and colonies are able to light up for sustained periods . each zooid in the colony has a pair of luminescent organs flanking the orals siphon . light production may be the result of intracellular bioluminescent bacteria in the cells of these luminescent organs but this needs to be confirmed . bowlby et al . ( 1990 ) showed how pyrosoma atlanticum and pyrosomella verticillata bioluminesce in response to light . if you shine light on zooids on the one side of the colony , they bioluminesce and their light stimulates adjacent individuals . in this way , the bioluminescence spreads over the colony from the point where the zooids were stimulated . a colony that lights up can in turn stimulate an adjacent colony to light up as well . at the same time as lighting up , the zooid closes its oral siphon and the cilia inside that cause the water flow , stop beating . colonies are negatively buoyant so when water flow stops , the colony starts sinking slowly . it is thought that the ability to bioluminesce in response to light stimulation might be an adaptation to communicating about predators and by also closing the water flow and sinking , they can move to a depth where there are fewer predators ( bowlby et al . 1990 ) .

a large population of the colonial pelagic tunicate pyrosoma atlanticum occurred in april 1991 in offshore waters of the ligurian sea ( northwestern mediterranean ) . the high numbers of colonies caught allowed their vertical distribution and diel migration in the 0–965 m water column to be described as a function of their size . daytime depths and amplitudes of the migration were correlated with colony size . the amplitude of the migration ranged from 90 m for 3 - mm - length colonies to 760 m for 51 - mm - length colonies , with a mean amplitude of 410 m for the whole population , all sizes pooled . the results of horizontal hauls at a given depth around sunrise and sunset showed a marked diurnal symmetry of the migratory cycle relative to noon , and that migration of the population was not cohesive . for example , the larger the colonies , the later after sunset they reached the upper layers during their upward migration .

pyrosomes , genus pyrosoma , are free - floating colonial tunicates that live usually in the upper layers of the open ocean in warm seas , although some may be found at greater depths . pyrosomes are cylindrical or cone - shaped colonies made up of hundreds to thousands of individuals , known as zooids . colonies range in size from less than one centimeter to several metres in length . they are commonly called
sea pickles
pyrosoma is a genus of colonial , pelagic ( open - ocean ) tunicates . colony size ranges from less than a centimeter to several meters in length . each colony forms a transparent tube , closed at one end and open at the other , that is composed of hundreds or even thousands of outward - facing individuals ( or zooids ) . these tiny zooids , each just millimeters long , are joined together by a gelatinous tunic . water is drawn into each zooid through an oral siphon by beating cilia , creating a feeding current . plankton are filtered out of the water and the depleted water is then expelled into the interior of the colony and out the posterior opening . this flow of water not only facilitates food acquisition , but also allows the colony to move by graceful jet propulsion , although pyrosoma are mainly planktonic ( passively free - floating ) .
pyrosomes are brightly bioluminescent , flashing a pale blue - green light that can be seen for many tens of metres . the name pyrosoma comes from the greek ( pyro =
fire
, soma =
body
) . pyrosomes are closely related to salps , and are sometimes called
fire salps
. sailors on the ocean are occasionally treated to calm seas containing many pyrosomes , all luminescing on a dark night .
as bizarre as they may seem , these animals are not uncommon to those sampling off oregon . but on our recent trip aboard the bell m . shimada , pyrosomes seem to be everywhere ! we have been getting numerous specimens in our three different sampling gears : vertical net , bongo net , and beam trawl . at one of our nearshore stations , the beam trawl brought up 2 . 5 gallons of pyrosomes ( fig . 3 ) ! we were also lucky to encounter a large aggregation at the surface on the newport line transect . this anomalous abundance of pyrosomes has been observed in other research cruises along the west coast . a long - term time series in the california current saw the highest catches ever of pyrosoma atlanticum in 2015 . pyrosomes have been mystifying beachcombers up and down the coast as they wash up on beaches . these gelatinous organisms join a list of other gelatinous zooplankton , such as aequorea spp . , doliolids , and the pteropod corolla spectabilis , that have been seen in large numbers over the past few years .
for more images of pyrosoma , check out bob perry’s photographs . included in his work are a few pseudoconchs ( false shells ) of the pelagic mollusk corolla which we similarly found . if you are interested in learning more about invertebrates with your students , i encourage you to look into the amazing animals curriculum unit i have written to introduce middle level students to zoology . this 10 - week unit is full of inquiry - based activities and lesson plans fully outlined for you .

/ / pyrosomes—fire bodies , ciliuminati , the enlightened ones—are washing up en masse in the monterey bay . these gelatinous cigars on the beach are marvels in the water , shining bright bioluminescence that lead t . h . huxley to exclaim :
i have just watched the moon set in all her glory , and looked at those lesser moons , the beautiful pyrosoma , shining like white - hot cylinders in the water
. this particular pyrosome was partnered with an isopod parasite at its opening , while the rest of the colonial tunicates created currents to filter food from fertile waters . depth : 6 fsw
a striking feature of pyrosoma tunicates is their dramatic bioluminescence , which is visible for several meters underwater and appears in waves within the colony as flashing by individual zooids is triggered by flashes from their neighbors . flashing can also be triggered by physical disturbance . when disturbed , individual zooids protect themselves by closing off their oral ( intake ) siphons , stopping the beating of their cilia , and emitting a flash of light . neighbouring zooids detect the flash with their photoreceptors and respond in turn with protective responses and light emission . protective responses thus spread by photic signalling and propagate from zooid to zooid through the colony ( mackie 1995 ) .
. . . sus densas agregaciones tienen un impacto sobre la comunidad fitoplanctónica que las rodea , debido a que p . atlanticum es una especie filtradora , que se alimenta principalmente de nanoplancton como cocolitofóridos , diatomeas , silico - flagelados y también de pequeños crustáceos . se han medido volúmenes de filtración de 35 l / h en colonias con un tamaño medio de 17 ' 9 cm ( perissinotto et al . [ 24 ] ) . en los últimos años se ha estudiado su papel en las cadenas tróficas marinas , siendo importante como presa para 62 especies de peces , tres de tortugas , dos de albatros y un león marino ( harbison [ 12 ] , james & stahl [ 14 ] , childerhouse et al .

among the rare species , d . krohni ( if clearly identified ) and doliolum denticulatum were exclusively found at 25–75 m and h . virgula at 75–125 m . c . polae was found in a moc10 sample at 50–100 m . p . atlanticum was collected at the sites between 575 and 750 m by day and within the upper 135 m by night . apart from d . nationalis which was represented solely by phorozooids , stages other than nurses at site a were most abundant in the 25–75 m - layer ( 206 . 0 ± 508 . 6 ind . 1 , 000 m −3 ) as compared to the adjacent 0–25 and 75–100 m - layers ( 8 . 7 ± 22 . 5 ind . 1 , 000 m −3 and 17 . 3 ± 32 . 9 ind . 1 , 000 m −3 , respectively ) , but the differences were not significant ( mann - whitney u - test , p > 0 . 05 ; n : 8 ; 8 ) .
a swarm of pelagic tunicate ( pyrosoma spinosum ) was found in the surface open waters of the arabian sea during late southwest monsoon ( september 2007 ) . the swarm site was characterized by moderate southwesterly wind ( approximately 7 m s −1 ) , relatively low sea - surface temperature ( approximately 26°c ) , shallow mixed layer ( approximately 50 m ) , and substantial macro - nutrient concentrations ( surface values : 2 . 5 μm nitrate , 0 . 3 μm phosphate , 0 . 9 μm silicate , and 5 . 0 μm ammonium ) . despite adequate macronutrient availability , the swarm site was characterized by low diversity of phytoplankton ( > 5 μm ) and mesozooplankton in the upper 200 m . low chlorophyll a concentration ( 27 . 3 mg / m 2 in the upper 120 m ) at the swarm site was dominated ( 90 % to 95 % in the upper 40 m ) by the synechococcus ( 20 × 10 6 / ml ) .

we had a unusual sighting these days , a fire roller . daniel , our skipper , was able to make a close and interesting video . this species are creatures of the open ocean . it is said that when they are carried by currents near to the shore they normally end up dying . the fire roller although having a strong body is nibbled at by fish an injured at rocks when it comes close to the shore . the body of this creature is composed by many thousands of tiny individuals forming a tube closed at one end , the tube can reach up to 3 meters each of the tiny individuals produces a current through its body into the tube ( in order to strain plankton from the water ) . as the water is ejected through the open end of the tube , a jet is created that slowly propels the whole colony . what a nice sighting ! !

each zooid is only a few millimetres in size , but is embedded in a common gelatinous tunic that joins all of the individuals . each zooid opens both to the inside and outside of the
tube
, drawing in ocean water from the outside to its internal filtering mesh called the branchial basket , extracting the microscopic plant cells on which it feeds , and then expelling the filtered water to the inside of the cylinder of the colony . the colony is bumpy on the outside , each bump representing a single zooid , but nearly smooth , though perforated with holes for each zooid , on the inside .
pyrosomes are planktonic , which means their movements are largely controlled by currents , tides , and waves in the oceans . on a smaller scale , however , each colony can move itself slowly by the process of jet propulsion , created by the coordinated beating of cilia in the branchial baskets of all the zooids , which also create feeding currents .
and evoked the following comment when seen by scientist t . h . huxley at sea :
pyrosomes often exhibit waves of light passing back and forth through the colony , as each individual zooid detects light and then emits light in response . each zooid contains a pair of light organs located near the outside surface of the tunic , which are packed with luminescent organelles that may be intracellular bioluminescent bacteria .
the waves of bioluminescence that move within a colony are apparently not propagated through neurons , but by a photic process .
flashing zooids not only stimulate other zooids within the colony to bioluminesce , but nearby colonies will also display bioluminescence in response . colonies bioluminesce in response to mechanical stimulation ( touch ) , as well as to light .

) thaliaceans can thus locally comprise an exceeding portion of the surface zooplankton standing stock in terms of numbers and biomass . by their capability of exploiting small particles over a wide size range , from bacteria to large diatoms and microzooplankton ( silver and bruland
; and references therein ) , in addition to the mass sinking of individual corpses ( wiebe et al .
different to the western mediterranean sea , thaliacean blooms have not been reported from the eastern mediterranean which is one of the most oligotrophic water bodies ( redfield et al .
) . hydrographically , the strong variability of the surface water circulation on different scales ( özsoy et al .
) can return nutrients to the exhausted surface water and thereby boost a local phytoplankton bloom ( salihoglu et al .
) which may be considered a general prerequisite for a flourishing thaliacean population ( e . g . wiebe et al .
) . no information , however , is available as to which extent thaliaceans are involved in the observed increase of zooplankton ( salihoglu et al .
) to an upward shift of the nutricline in the course of the eastern mediterranean transient , emt ( klein et al .
) . although the thaliacean population was small relative to other taxa , we present the data on the populations of species and their ontogenetic stages , with a focus on regional abundance and vertical distribution , in order to provide basic information for the evaluation of the yet unknown role of thaliaceans in the levantine sea ecosystem .

thaliaceans were collected from the upper 1 , 050 m , yet chiefly in the upper 450 m . within the latter range 50 m - intervals were fished with the d - moc per haul between 425 and 25 m , in addition to the top 25 m . off site c , the uppermost layer was 0–35 m , due to an offset of the pressure meter and the depth ranges of the 50 m - intervals had changed accordingly .
the mean water volume filtered at the 50 m - intervals was 332 m 3 ( sd ± 105 m 3 ) at the sites a and b and 300 m 3 ( sd ± 78 m 3 ) at site c . this is about double as high as the mean filtered in the respective uppermost 25 or 35 m ( a 146 ± 44 m 3 , b 172 ± 18 m 3 , c 156 ± 38 m 3 ) . in total , five day - time and four night - time profiles were available from site a , and two day and two night samples each from sites b and c .

) except for the blastozooid stages ( phorozooid and gonozooid ) . but even their species - specific determination is cumbersome . therefore , the specimens of a rich sample at site a were not discriminated .

renato agazzi marked the classification from
integrated taxonomic information system ( itis )
as preferred for
candoia carinata schneider 1801
.
taxonomic note : the recent revision of the candoia carinata complex , which basically recognized the various populations defined by sam mcdowell , has elevated its two subspecies to full species status and defined eight subspecies between them . in addition a third species , with two subspecies has been described . the form occurring on karkar island is the nominate candoia carinata carinata .
johann gottlo schneider originally described boa carinata in 1801 , and in 1842 thanks to john edward gray become candoia carinata . four more snakes were later added to the same genus . candoia bibroni bibroni was described as enygrus bibroni by dumeril _ bibron in 1844 . there’s also another subspecies of candoia bibroni known as c . b . australis .

distribution : not on the solomon island ( mccoy 2015 ) . until recently the species was considered a subspecies of candoia carinata , which is found throughout most of the solomon islands archipelago ( harlow and shine 1992 ) . it is now a full species , but due to a lack of specific data , much of the available information refers to candoia carinata ( smith et al 2001 , o . tallowin in iucn 2012 and pers . comm . , 23 nov 2016 ) .

what is candoia ? candoia is a family or genus of snakes that includes 3 valid species at the time of this writing . further taxonomic research may show candoia to include 5 or more valid species within the genus . they are small boas , normally between 2 & 3 feet , which occur in many different sizes , colors and patterns .

one of the easiest aspects of candoia husbandry is the ease of sexing your specimens . there is never a need to probe or pop any candoia species . to sex any specimen , just look for spurs or absence of spurs on either side of the vent . male candoia of all species have very large hooks for spurs . females have no spurs at all . it is very easy to see provided you are looking in the correct place . all male candoia are smaller than females .

thus all distinctive features of the lectotype of boa carinata conform with those of other material from the stated type locality of ambon , which we conclude cannot be contested .
hi all : ) , i want to ask does anybody have a candoia carinata carinata ? what do you give them for food ? because i have a plan to give mine a pinkies , but my friend said that it would be no good for the diggestion , because in the wild the used to have a lizard or a gecko for food . . i need your suggestion then , is it true what my friend opinion is ? ps : i ' m sorry if my english is bad : ( - - bram - -
candoia look venomous , particularly the viper boa , which in its native habitat is killed routinely by humans who mistake it for the highly venomous death adder .
the other species in candoia are candoia aspera , from new guinea , with two subspecies ( c . a . aspera and c . a . schmidti ) , and c . bibroni , from samoa to the solomons , also with two subspecies ( c . b . bibroni and c . b . australis ) .
candoia carinata has been assessed as least concern . it has a large distribution occurring in eastern indonesian islands , new guinea , the bismarck archipelago and admiralty islands . it is not likely to be affected by any significant threats and is present in many protected areas . it has been recorded in the pet trade but this is not posing a threat at present .
sorry i didnt asnwer you previously but i think anubis is a perfect name for your wee fella : ) carinata remind me of ancient egypt for some reason , maybe the shape of the head .
subspecies : smith et al . ( 2001 ) elevated c . c . paulsoni to full species status and stated the existence of 2 subspecies of c . carinata ( carinata and tepedeleni ) . in addition , these authors revalidated another species , c . superciliosa ( günther 1863 ) with 2 subspecies , c . s . superciliosa and c . s . crombiei from ngeaur island in the belau archipelago .

as with all tropical species , temperature plays a vital role in a candoia environment . i keep the ambient temperature at approximately 80 - 84 degrees year round . a brief winter cool down is needed for breeding candoia species . humidity is kept between 50 - 80 % with occasional cage misting . i have witnessed some specimens become restless or uneasy when exposed to temperatures near 90 degrees .
gravid females also tend to stay away from their heating pads . temperature is not a major concern for candoia maintenance . they will do just fine at room temperature and require no special needs .

our own studies of geographic variation indicate that the species as currently recognized does indeed constitute a complex of several taxa . resolution of nomenclature for those taxa hinges upon fixation of the earliest name applied in the complex , schneider ' s boa carinata .
all other candoia species average 5 - 20 young per litter . i highly recommend giving a female a year off after giving birth . too much stress can be detrimental to her health and future breeding success .
a third , apparently completely distinctive feature of typical c . carinata is the presence of at least weak keels on some part of the 2nd scale row , as in the lectotype . keels do not occur on the 2nd scale row in any material from elsewhere .
c . carinata ( schneider’s bevelnosed boa ) from eastern indonesia , new guinea & bismarcks . c . carinata carinata ( western schneider’s bevelnosed boa ) from east indonesia & new guinea . c . carinata tepedeleni ( tepedelen’s bevelnosed boa ) from bismarck archipelago . c . paulsoni ( paulson’s bevelnosed boa ) from eastern indonesia , new guinea & solomons . c . paulsoni paulsoni ( solomon bevelnosed boa ) from solomon islands , excl . bougainville . c . paulsoni mcdowelli ( mcdowell’s bevelnosed boa ) from png & louisiade archipelago . c . paulsoni rosadoi ( rosado’s bevelnosed boa ) from misima island , louisiade archipelago . c . paulsoni sadlieri ( sadlier’s bevelnosed boa ) from woodlark island , louisiade archipelago . c . paulsoni tasmai ( tasma’s bevelnosed boa ) halmahera & northeastern sulawesi , indonesia . c . paulsoni vindumi ( vindum’s bevelnosed boa ) from bougainville & buka . c . superciliosa ( belau bevelnosed boa ) from palau archipelago . c . superciliosa superciliosa ( northern belau bevelnosed boa ) from babeldaob to beliliou . c . superciliosa crombei ( ngeaur bevelnosed boa ) from ngear , southern palau .
@ isaac : now you give your candoia pinkies ? yep , pinkies when he was starting out , we were doing fresh , tiny pinkies - about 1 gram each . he ' s up to 2 - 3g pinks now : )
no evidence exists that more than one taxon of the c . carinata complex occurs on ambon island or anywhere else in the south moluccas or irian jaya . nevertheless , it is also important that the morphological features of the lectotype conform with those of other material known to have originated in that area , thus substantiating the purported source of the lectotype from the stated locality .
fixation of application of the name c . carinata , through discovery of the lectotype , clarification of type locality , and analysis of the characteristics of the lectotype , removes all uncertainty in application of other names , such as enygrus superciliosus günther ( 1863 ) and e . c . paulsoni stull ( 1956 ) to the complex , as junior synonyms or for separately valid taxa .
we are much indebted to thomas ziegler for the photographs ; to dr . k . l . williams for vital aid with the literature ; to kamuran tepedelen and vern veer for access to both live and preserved specimens of c . carinata ; to dr . kraig adler for bibliographic aid ; and to numerous institutions and their curators for the loan of specimens from their collections .
australis is smaller and more slender , the 2 species look remarkably similar . more scientific and taxonomic studies are needed to confirm major differences in these and other candoia species . fiji boas can reach maximum lengths of 3 - 4 feet for males and over 7 feet for females . average size is 3 - 6 feet .
in their native habitats some candoia begin life eating amphibians and lizards then switching to mammals and birds later on . if you plan to own candoia in the future , we cannot recommend enough that you demand captive bred snakes . the reason is it can be very difficult to bring in a wild caught snake , used to eating lizards and amphibians , and then getting it to switch over to a rodent diet . i’m not saying it cannot be done , just that it’s best to avoid that situation if possible . feed appropriate size euthanized mice and rats . we prefer to buy in bulk frozen rodents which we later defrost in warm water .
* special note : because i moved to new brunswick i cannot keep candoia spp at all in the province . however , two hours away the species is allowed . ironic isn’t it , i mean what exactly are the environmental impact differences that the two provinces face ? want to find out more about this and other issues facing canadian herpetoculture ? join urltoken right now !
over 300 specimens have been examined for comparison from all parts of the range of the species , enabling us to compare the features of the lectotype with those of populations in all parts of the range of the species . especially critical is the presence of a conspicuous white postanal spot , immediately following the anus ; the spot is invariably present in the morphologically uniform populations of the south moluccas , irian jaya , northern papua new guinea , new britain and new ireland , all regarded as typical c . carinata . there is , indeed , no way to limit the origin of the lectotype morphologically to any one of those regions . a white , immediately postanal spot occurs elsewhere in the c . carinata complex only in the palau population , which , however , has fewer than 9 intersupraoculars ( 4 - 7 , n = 29 ) , usually fewer anterior scale rows ( 25 - 27 , 28 occurring in only two of 29 ) , and several other average differences .
as published by böhme and bischoff ( 1984 , see also myers and böhme , 1996 ) , the entire collection of the zoological museum of göttingen was transferred to the zoologisches forschungsinstitut und museum alexander koenig ( zfmk ) , bonn , in 1977 . the specimen included by schneider ( 1801 ) in his syntype series of boa carinata and designated as lectotype by mcdowell ( 1979 ) is from
amboina
( = ambon ) and is now cataloged as zfmk 35503 ( figures 1 , 2 ) .
the entire genus candoia is one that would be considered tropical species . when keeping tropical species three things should come to mind : heat , humidity and uvb . some may have said humidity and heat . in addition to heat , most tropical reptiles in our experience also require humidity and uvb . with snakes it’s a long standing presumption that snakes don’t benefit from uvb . however , we’ve not seen reports of blood calcium levels which would prove uvb is not necessary .
for the more fossorial ( burrowing ) or terrestrial ( surface ) dwelling species of candoia we offer two hide boxes of appropriate size . the snake can go inside the box , curl itself up and have its sides touching the hide box interior . we place a hide box on each side of the enclosure , one on the cool side and one on the basking side . this allows the snake to thermoregulate while being hidden and feeling secure if they so choose .
it is truly amazing to see a 26 inch male paulsoni on the back of a nearly 5 foot female . but yet , they get the job done and in approximately 7 - 9 months a litter of neonates will be born . as with all boas , candoia give birth to live young . paulsoni litters are the largest , with total amounts of nearly 100 babies at a time possible . standard size litters average 20 - 40 for a normal size 3 - 4 foot female .
if you’re a regular reader skip the next two sentences . you shouldn’t use colored lights as they will disrupt the normal circadian rhythms of the reptile . we have explained this in the article “ colored lights and other myths the pet store told me . ” ceramic heating elements are the best way to go . sometimes the enclosure you’re using needs an alternative way of heating . therefore , we have what are known as under tank heaters which make for excellent secondary heating source with the candoia spp .
: sexing aspera , as well as all candoia , is extremely easy . they males have predominant spurs protruding from either side of the cloaca . if these are present then you have a male although some females will have very small spurs too . the females also have a slightly shorter tail , but popping is almost never necessary to sex the snake properly . of course , as all of you well know , the only 100 % way to know the sex of a snake is to probe it properly .
why decor is not covered more often within herpetoculture is beyond us here at reptile apartment group , but that’s another topic . for now suffice it to say , in our experience an enriched environment with various types of decor appears to have a direct correlation with a healthy snake . not just physically , but also their behaviours seem to be calmer and not as flinching when a naturalistic environment is provided . live plants should be offered for candoia not only low growing plants for cover but also some taller species .
a second generally distinctive feature of south moluccan populations is the relatively long tail , as noted by mcdowell ( 1979 ) , who struggled with an analysis of its possible taxonomic significance . the lectotype number of 45 subcaudals , even though incomplete , occurs within the range of 45 - 53 that occurs in south moluccan c . carinata ( n = 21 ) , and is matched elsewhere only in misima island specimens ( 49 - 50 , n = 3 ) . none is as high as 45 in material from bougainville and halmahera ( n = 52 ) , in only 3 % in material from central and southern papua new guinea ( n = 29 ) , although in 25 % of specimens from the solomons ( n = 56 ) and 45 % in palau material ( n = 20 ) . concomitantly , the tl / ttl ratio is consistently higher in typical c . carinata , including the holotype with a ratio of . 16 ; 81 % of south moluccan specimens have a ratio of . 16 or higher , whereas 0 % occurs in material from halmahera and central and southern papua new guinea ( n = 55 ) , 4 % in bougainville ( n = 23 ) , 5 % in the solomon islands ( n = 55 ) , 15 % in palau ( n = 20 ) , and 33 % in misima ( n = 3 ) .
at first glance , that may seem an odd combination substrate and humidity . the two are interwoven and will play a major role in keeping a healthy candoia in captivity . substrates are like the heating sources , where there are numerous opinions and they all claim to be right . to cut to the chase of the substrate , we recommend and use earthgro organic orchid bark and earthgro organic soil for all of our tropical species of reptiles , amphibians , and invertebrates . for the boas we will often tear up and place a few mats of sphagnum moss to hold more moisture . if you’d like to read a more in depth treatise on substrates then we recommend the substrates : getting your hands dirty article .

and other stimuli will cause these changes . despite their common name , ground boas will use branches if provided . many will ambush their prey while hanging from the branch . a large water bowl is very much needed as paulsoni love to soak .
adults can reach maximum lengths of 3 feet for males and 5 feet for females but average in the 2 - 4 foot range .
australis are semi - arboreal and need sturdy branches to climb on in addition to a large water bowl . most specimens are fairly calm and deliberate , but once in a while you will run into a nasty individual . adults can reach maximum sizes of 3 - 4 feet for males and nearly 7 feet for some females . average size is 3 - 5 feet .
beautiful colors and patterns can then be seen , and that dull brown snake may turn into a golden beauty . these snakes will readily accept rodents in captivity . they prefer rat pups over adult mice . stubborn feeders may need a little more time to acclimate . scenting methods can be used if the specimen starts to lose weight . not all aspera are nasty . i own many specimens which can easily be picked up and handled without incident . aspera will often spend all or most of their day in the water bowl . they will use the water bowl for defecating and also breed while in the water . maximum size for viper boas is 24 - 36 inches but average approximately
once your neonates are established rodent feeders they will begin to grow fairly quickly and will double their size within the first 6 months . lizard and frog feeders will slowly catch up with the growth rate of their siblings after the switch over to pinkies . i have also seen several instances of
cannibalism with neonate paulsoni . this has occurred when several hungry neonates were housed together . it does not happen when they become established feeders .
it is especially noticeable in paulsoni , where most males are dwarfed by females that may be 10 times larger and heavier .

i bred these alot of years ago started the babies by assist feeding mice tails and slowly one by one they started taking them on there own . they were hard to get going but once started i never had any problems after . kept them on kitchen roll and warm damp moss , hope this may help a little
got a pair of these from cpr at the weekend . they were non / assist feeders . tried assist feed tonight , but both released the pinky as soon as they had the chance . hoping that they will assist feed once settled a little more . have also just ordered lizard maker , fingers crossed . so i am also looking to hear opinions and experiences that others have had in getting them to feed .

i don ' t mind assist feeding really , and he / she is taking it really easily now ( was a bit of a struggle at first ) , but obviously it isn ' t the ideal solution . oh well , i ' ll keep trying ! i ' ve been told to try a live frog but unless i could find a day old tree frog or something i don ' t think that ' d fit either . . . and even if i could , it ' s not something i could provide weekly so wouldn ' t exactly be a solution .

thank you for taking the time to provide feedback on the iucn red list of threatened species website , we are grateful for your input .
justification : this species is listed as least concern in view of its wide distribution , large overall population , and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category . however , as the species is seen in trade , further research and monitoring of harvest and trade levels is recommended .
this widespread species ranges through the solomon islands , vanuatu , the loyalty islands ( but not mainland new caledonia ) , fiji , tokelau , wallace and futuna islands , samoa , american samoa , and tonga . it is found up to 1 , 200 m asl .
this species is probably reasonably common to uncommon over its wide range . the population is probably stable across the range as a whole , but is perhaps decreasing somewhat in the central pacific .
this snake is found in trees , bushes and rock clefts in a range of forests including lowland forest , coastal vegetation and dry forest ( morrison 2003 ) . animals have been recorded as abundant in mangroves ( m . mccoy pers . comm . november 2011 ) . it can be found in cacao plantations . it is an ovoviviparous species .
there appear to be no significant threats to this species , although , as with many snakes , animals are frequently killed on sight by people . it is found in trade , but the effects of this are unknown .
this species is present in some protected areas . it is listed on appendix ii of cites . further research and monitoring of harvest and trade levels is recommended .
to make use of this information , please check the < terms of use > .
this species has a large distribution , ranging from the eastern indonesian islands , new guinea to the bismarck archipelago . in indonesia it has been recorded on the minahassa peninsula , sangihe and talaud islands in northern sulawesi , tanimbar islands , seram and the other northern maluku islands ( in de bosch 1985 , o’shea 1996 ) . in indonesian new guinea it occurs throughout west papua province and across the northern coastal region to the huon peninsula of moreby province , papua new guinea . it is found in the south west of papua new guinea in western and gulf province . it is also found throughout the bismarck archipelago and admiralty islands . it is found at elevations from sea level to around 1 , 525 m asl . ( o’shea 1996 ) .
this species can be found in a variety of habitats from rainforests to caves and also disturbed environments such as plantations and rural gardens ( o ' shea 1996 ) . typical of snakes of this genus , this species is generally found either on or close to the ground ( foufopoulos and richards 2007 ) . it is viviparous with a clutch size of up to six . its diet consists primarily of skinks but may also take gecko eggs and frogs ( o’shea 1996 ) .
there is no population information available for this species but its population is probably stable .
yuwono ( 1998 ) recorded the trade of this species from indonesian new guinea , and that thousands of specimens could be collected if required . natusch and lyons ( 2012 ) noted the trade of this species from jayapura and the vogelkop in indonesian new guinea . sixteen and eighty - three individuals ( respectively ) were recorded at wildlife traders between september 2010 - april 2011 . this species is listed under cites but does not have protected status in indonesia . the cites quota for this species was 400 from papua and 400 from west papua .
it is unlikely that any major threats are impacting this species . it is present in the pet trade but current levels are unlikely to be posing a significant threat to this species .
this species is listed under appendix ii of the convention on international trade in endangered species of wild fauna and flora ( cities ) ( urltoken ) .
this species has protection status in papua new guinea but not in indonesian new guinea ( natusch and lyons 2012 ) .
this species occurs in protected areas in new guinea and the bismarck archipelago . monitoring the trade and harvest levels of this species is recommended .

the most common snake inhabiting coconut husk piles on karkar island is the new guinea ground boa .
bismarck ground boa ( c . aspera aspera ) from new britain and new ireland , and new guinea ground boa ( c . aspera schmidti ) from new guinea ( west papua and papua new guinea ) and its continental islands including karkar . the scale counts defining the two subspecies are listed in the table below .
in addition , a single new ireland juvenile compared with several juvenile karkar island specimens , was found to be of more slender build , have a longer tail , a raised vertebral ridge and lighter coloured eyes but all those characters are relative and the sample was small .
