sacc . 2005 and updates . a classification of the bird species of south america . available at : urltoken .

justification : this species has an extremely 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 ) . the population trend appears to be stable , and hence the species does not 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 .

the global population size has not been quantified , but this species is described as ' fairly common ' ( stotz et al . ( 1996 ) . trend justification : the population is suspected to be stable in the absence of evidence for any declines or substantial threats .

the embryos of all arthropods are segmented , built from a series of repeated modules . the last common ancestor of living arthropods probably consisted of a series of undifferentiated segments , each with a pair of appendages that functioned as limbs . however , all known living and fossil arthropods have grouped segments into tagmata in which segments and their limbs are specialized in various ways .

nearly all animals make use of some form of sexual reproduction . [ 20 ] they produce haploid gametes by meiosis ; the smaller , motile gametes are spermatozoa and the larger , non - motile gametes are ova . [ 21 ] these fuse to form zygotes , [ 22 ] which develop via mitosis into a hollow sphere , called a blastula . in sponges , blastula larvae swim to a new location , attach to the seabed , and develop into a new sp

bothrops , crotalus and lachesis represent the most medically relevant genera of pitvipers in central and south america . similarity in venom phenotype and physiopathological profile of envenomings caused by the four nominal lachesis species led us to hypothesize that an antivenom prepared against venom from any of them may exhibit paraspecificity against all the other congeneric taxa .

at the antivenom / venom ratio of 500 μl antivenom / mg venom , the bcl and bl polyspecific antivenoms and the monospecific l antivenom , effectively neutralized the lethal activity of the seven lachesis venoms investigated ( table 5 ) . the monospecific ab antivenom only neutralized the lethal activity of l . stenophrys , l . muta muta ( cascalheira ) and l . muta rhombeata ( recife ) ( table 5 ) , while the monospecific ac antivenom was unable to neutralize the lethal activity of any of the lachesis venoms studied at the ratio of 500 μl antivenom / mg venom ( table 5 ) .

to assess this hypothesis , in this work we have applied antivenomics and immunochemical methods to investigate the immunoreactivity of three monovalent antivenoms and two polyvalent antivenoms towards the venoms from different geographic populations of three different lachesis species . the ability of the antivenoms to neutralize the proteolytic , hemorrhagic , coagulant , and lethal activities of the seven lachesis venoms was also investigated .

/ case reports / two patients bitten on their hands / by a lachesis muta / were left with permanent contractures , and hypotension and hemorrhage were commonly recorded on admission . one patient was severely confused .

no significant differences were found in the levels of specific antibodies against lachesis venoms present in the bcl antivenom , and the ab and al antivenoms ( s1 fig ) . the highest titer corresponded to the binding of bl antivenom to l . stenophrys , l . m . muta ( colombia ) , l . m . muta ( cascalheira ) , and l . m . rhombeata ( recife ) venoms , whereas the titer of this antivenom against venoms from l . melanocephala , l . m . muta ( peru ) and l . m . muta ( tucurui ) was indistinguishable from that of the bcl antivenom ( s1 fig ) . monospecific ac antivenom exhibited the lowest reactivity against the seven lachesis venoms analyzed ( s1 fig ) .

the bcl and bl antivenoms , and the monospecific l antivenom effectively neutralized the hemorrhagic activity of all the lachesis venoms studied ( table 3 ) . the bl antivenom showed the highest neutralization capacity of the hemorrhagic activity than any of the other antivenoms used in this study ( table 3 ) . the monospecific ab antivenom was only able to neutralize the hemorrhagic activity of l . stenophrys and l . melanocephala venoms , whereas the monospecific ac antivenom was unable to neutralize the hemorrhagic activity of any of the venoms ( table 3 ) .

the reproductive cycle is seasonal , mating occurs in february and march , the eggs are deposited from june to august , and birthing takes place from august to october but sometimes in november ( chacón and valverde , 2004 ) . in captivity , females reach sexual maturity at approximately 1 . 6 m in total length and at about five years of age ( solórzano , 2004 ) . furthermore , there have been many fruitful efforts to maintain and breed lachesis stenophrys in captivity ( boyer et al . , 1989 ; ripa , 1994 ; de souza , 2007 ) .

/ case reports / after a snakebite by the costa rican bushmaster lachesis stenophrys , a 64 - year - old patient developed cardiovascular shock and coagulopathy . after intensive care and antivenom treatment , he was discharged after 4 days but had to be hospitalized again 3 days later because of abdominal pain and bowel obstruction . an emergency laparotomy revealed a necrotic ileum and cecum , and an obstruction of the superior mesenteric artery . until now , this type of intestinal ischemic complication after a snakebite has not been reported in the literature . the effects of bushmaster venom are discussed .

/ case reports / three out of four cases of snake bite by lachesis muta stenophrys ( bushmaster ) in costa rica were fatal and one recovered after a long period of hospitalization . initial symptoms were similar to those of bothropic envenomation : intense pain , nausea , vomiting , sweating , and excitability , but differing in the magnitude of a tremendous edema and in the absence of intensive bleeding and phlyctenae . we found important alterations in arterial blood pressure and in the activity and concentration of coagulation factors . all patients showed infections , and necrosis was found in at least three of them .

despite the broad geographic distribution of lachesis , antivenoms against venoms of different species are effective in the neutralization of congeneric venoms not used in the immunization mixture , indicating that they can be used equivalently for the clinical treatment of any lachesic envenoming .

there is only one species of bushmaster ( lachesis muta ) found in brazil . it is the largest venomous snake in brazil measuring up to 14 . 75 feet in length . the viperidae family ( genera lachesis , bothrops and crotalus ) as well as the elapidae family have accounted for all the envenomations in brazil . the extent of the problem is shown in the following statistics : 31 , 148 envenomations in 2011 with 143 deaths ; 29 , 322 envomations in 2012 with 129 deaths and 25 , 302 envenomations with 108 deaths .

this study demonstrates that antivenoms raised against venom of different lachesis species are indistinctly effective in the neutralization of congeneric venoms not used in the immunization mixture , indicating that antivenoms against conspecific venoms may be used equivalently for the clinical treatment of envenomings caused by any bushmaster species .

in costa rica lachesis stenophrys is the longest venomous snake reaching approximately a total length of 2 . 5 m . its distribution is along the caribbean versant of nicaragua to western and central panama ( campbell and lamar , 2004 ) , and in costa rica is found in tropical and subtropical rainforest on the caribbean versant . it is an uncommon species even though in certain protected areas remains relatively common ( solórzano and cerdas , 1986 ; zamudio and greene , 1997 ) . the species of this genus are the only ones in the new world that lay eggs instead of giving birth to newborns with the possible exception of bothrocophias colombianus ( savage , 2002 ; campbell and lamar , 2004 ; solórzano , 2004 ) .

the terrariums in which the lachesis stenophrys were housed have the following dimensions : 1 . 2 m ( wide ) x 2 . 4 m ( long ) x 0 . 9 m ( tall ) ; they have a shelter that provides refuge to the snake , ad libitum water supply , and a log and rocks to facilitate the shedding of skin , and some large dry leaves . different layers compose the substrate ; the first layer is made of small stones and rocks , which work as filter and keep humidity inside the terrarium ; then a thin layer of river sand or substrate , and at last a layer of large dry leaves . this substrate composition prevents the animals to be directly exposed to constant humidity , which could lead to severe ventral infections .

/ case reports / in venezuela a patient developed intense sweating , vomiting , watery diarrhea , hypersalivation , conjunctival suffusion , hypotension , bradycardia , and respiratory distress 45 minutes after being bitten by a juvenile / lachesis muta / . this patient also showed neurotoxic signs : divergent strabismus , dysarthria , and dysphagia .

de souza ( 2007 ) , showed that l . muta rhombeata displayed sexual activity after storms or strong raining and furthermore boyer et al . ( 1989 ) , showed that a drop in temperature and an increase in humidity triggers hormonal response in bushmaster females . in agreement , we observed that the sexual activity starts at the end of december in costa rica , when the temperature falls , and continues until march . an interesting point is that the animals ( both sexes ) fasted during the season of mating and breeding , which we found to be a good indicator of the sexual activity of the snakes . in contrast , ripa ( 1994 ) found no sexual activity in lachesis stenophrys females despite the temperature / humidity changes . instead , he found that the use of chemical secretion left by l . melanocephala pairs would trigger a sexual response . on the other hand , solórzano ( 2004 ) showed that the mating season of l . stenophrys takes place during february and march and the females display a biannual reproductive cycle . nevertheless , we had two consecutive breeding seasons by two different bushmaster females . additionally , we found that isolation of females until shed their skins in mating season , and a later reintroduction of the male without removing the skin function as a sexual stimulus .

the bcl and bl polyspecific antivenoms , and the monospecific l antivenom effectively neutralized the coagulant activity of lachesis venoms from the seven bushmaster taxa sampled ( table 4 ) . the bl antivenom showed the highest coagulant neutralization activity than any of the other antivenoms use in this study ( table 4 ) . on the other hand , neither the ab nor the ac monospecific antivenoms were able to neutralize the coagulant activity of any of the lachesis venoms used in this study ( table 4 ) . these data agree with a previous work showing the inefficacy of monospecific bothropic antivenom in the neutralization of the coagulation activity of l . m . muta venom [ 54 ] .

monospecific antivenoms showed significantly more limited immunorecognition profiles than bcl and bl antivenoms toward venoms of all lachesis taxa investigated . the three monospecific antivenoms , but particularly the anti - crotalic ( ac ) antivenom , exhibited poor binding ability towards most venom proteins , including pla 2 s , crisp , gal - lectin , svsps , pi - and piii - svmps and lao . the average toxin immunocapturing activity of this monospecific antivenom was 16 % ( l . stenophrys ) , 21 % ( l . melanocephala , ) , 21 % ( l . m . muta colombia ) , 9 % ( l . m . muta peru ) , 9 % ( l . m . muta cascalheira ) , 17 % ( l . m . muta tucurui ) , and 19 % ( l . m . rhombeata ) ( panels i of figs 2 – 8 , respectively ) .

comprehensive transcriptomic and proteomic studies across lachesis [ 23 – 26 ] have revealed remarkably similar venom phenotypes comprising seven or eight toxin families , including bradykinin - potentiating / c - type natriuretic peptide ( bpps / c - np ) , zn 2 + - dependent snake venom ( sv ) metalloproteinase ( svmp ) , serine protease ( svsp ) , phospholipase a 2 ( pla 2 ) , l - amino acid oxidase ( laos ) , c - type lectin - like ( ctl ) , and in venoms of the south american species , also cysteine - rich secretory protein ( crisp ) . ontogenetic changes in the toxin composition of l . stenophrys venom result in the net shift from a bpps / c - np - rich and svsp - rich venom in newborns and 2 - years - old juveniles to a ( pi > piii ) svmp - rich venom in adults [ 24 ] .

antivenoms were serially diluted by a factor of 3 ( starting from a dilution of 1 / 500 ) and tested by elisa against the following crude lachesis venoms : l . stenophrys from costa rica ( a ) , l . melanocephala from costa rica ( b ) , l . muta muta from colombia ( c ) , peru ( d ) , the brazil regions of cascalheria ( e ) , tucurui ( f ) , and l . muta rhombeata from recife , brazil ( g ) . antivenom acronyms , bcl , polyspecific anti - bothropic , anti - crotalic , anti - lachesic antivenom from instituto clodomiro picado ( cr ) ; bl , anti - bothropic and anti - lachesic antivenom from instituto vital brazil , niterói , brazil ; al , monoespecific anti - lachesic antivenom ; ab , monoespecific anti - bothropic antivenom ; ac , monoespecific anti - crotalic antivenom . each point represents the mean ± sd of three independent determinations .

human bites by lachesis species are not frequent but when occur cause severe envenoming due to large amount of venom ( 200–411 mg ) injected into the victim and also owing to its toxicity in humans , as reported for snakebites in brazil , colombia and costa rica [ 11 – 21 ] . common local effects include agonizing burning - throbbing pain , mild hemorrhage , edema , and blister formation . these signs and symptoms are accompanied by systemic alterations , such as hemorrhage , coagulopathy , cardiovascular collapse , and by the so - called “ lachesis syndrome” , an alteration of the autonomic nervous system which manifests with profuse sweating , abdominal colic , nausea , recurrent vomiting , watery diarrhea , diastolic and systolic hypotension , and sinus bradycardia , together with sensorial disorders ( uncoordinated march , lapses of unconsciousness ) and serious hemodynamic alterations within 15–20 min after a bite [ 12 – 19 , 22 ] .

the bcl and the bl therapeutic antivenoms , and the monospecific al antivenom effectively neutralized the proteolytic activity of venoms from the 7 lachesis taxa investigated ( table 2 ) . the bl antivenom showed higher neutralization activity than the other antivenoms used in this study ( table 2 ) . the ac monospecific antivenom was only able to neutralize the proteolytic activity of l . melanocephala venom ( table 2 ) . the ab monospecific antivenom was unable to neutralize the proteolytic activity of any of the venoms ( table 2 ) .

several toxic and enzymatic activities of the venom of lachesis muta melanocephala were studied . this venom has many similarities with that of l . m . stenophrys , although there are quantitative differences in venom activities , as well as in the immunodiffusion patterns of these venoms when reacted against polyvalent antivenom . this antivenom was tested for its ability to neutralize a series of toxic and enzymatic effects of l . m . melanocephala venom . a new method to study myonecrosis , based on the quantitation of residual creatine kinase in injected muscle , was used . antivenom was highly effective in neutralizing lethal , hemorrhagic , myotoxic , edema - forming , defibrinating , caseinolytic and fibrinolytic activities when venom and antivenom were incubated prior to the test or , in the case of edema - forming activity , when antivenom was administered before venom injection . on the other hand , when antivenom was injected i . v . at different time intervals after venom injection neutralization of lethality was good , although neutralization of local effects , i . e . hemorrhage and edema , was poor . these results indicate that polyvalent antivenom contains antibodies capable of neutralizing toxic and enzymatic activities of l . m . melanocephala venom . moreover , the partial inability of antivenom to neutralize local effects when administered after venom injection is probably due to the rapid development of these effects once venom is injected . pmid : 3672541

except for the bpps , both polyspecific antivenoms efficiently immunocaptured all the components from l . stenophrys ( fig 2 ) , l . m . muta ( colombia ) ( fig 4 ) and l . m . rhombeata ( fig 8 ) venoms . in addition , the bl antivenom immunocaptured the venom components of l . m . muta from the brazilian localities cascalheira ( fig 6 ) and tucurui ( fig 7 ) . the apparent low recovery of pi - and piii - svmps ( eluting from the rp - hplc column at 40–42 min ) in the immunoaffinity captured fractions of the bcl and bl affinity columns ( figs 2 – 8 , panels b and d , respectively ) may be ascribed to the high affinity of these venom proteins for the antivenom molecules , as has been demonstrated in a previous work [ 25 ] .

/ laboratory animals : acute exposure / the ability of crude venom and a basic phospholipase a ( 2 ) ( lmtx - i ) from lachesis muta muta venom to increase the microvascular permeability in rat paw and skin was investigated . crude venom or lmtx - i were injected subplantarly or intradermally and rat paw edema and dorsal skin plasma extravasation were measured . histamine release from rat peritoneal mast cell was also assessed . crude venom or lmtx - i induced dose - dependent rat paw edema and dorsal skin plasma extravasation . venom - induced plasma extravasation was inhibited by the histamine h ( 1 ) antagonist mepyramine ( 6mg / kg ) , histamine / 5 - hydroxytriptamine antagonist cyproheptadine ( 2 mg / kg ) , cyclooxygenase inhibitor indomethacin ( 5mg / kg ) , nitric oxide synthesis inhibitor l - name ( 100 nmol / site ) , tachykinin nk ( 1 ) antagonist sr140333 ( 1 nmol / site ) and bradykinin b ( 2 ) receptor antagonist icatibant ( 0 . 6mg / kg ) . platelet - activating factor ( paf ) antagonist pca4248 ( 5 mg / kg ) had no effect . lmtx - i - induced skin extravasation was inhibited by cyproheptadine , mepyramine , indomethacin and pca4248 , while l - name and sr140333 had no effect . additionally , both lachesis muta muta venom and lmtx - i concentration - dependently induced histamine release from rat mast cells . in conclusion , lachesis muta muta venom and lmtx - i increase microvascular permeability by mechanisms involving in vivo mast cell activation and arachidonic acid metabolites . additionally , crude venom - induced responses also involve substance p , nitric oxide and bradykinin release , whether lmtx - i - induced responses involve paf .

/ case reports / / out of / 4 cases from costa rica , three of the victims died within 3 - 5 days / after being bitten by a lachesis muta / despite antivenom treatment . they had developed shock associated with massive local swelling and secondary infection , but spontaneous bleeding appeared less common than with envenoming by bothrops species . . . . bleeding from the fang marks / was observed , along with / epistaxis , hematemesis , hemoptysis , and hematuria in the 4 cases . the only survivor was left with severe contractures of the bitten arm .

/ case reports / we report a case of envenomation caused by a bushmaster ( lachesis muta ) in a male child in state of pernambuco , brazil . the victim showed discrete local manifestations , but presented altered blood coagulation 2 hours after the bite . ten ampoules of bothropic - lachetic antivenom therapy were administered , and 48 hours later , the patient showed discrete edema , pain , and ecchymosis around the bite and normal blood coagulation . the patient was discharged 5 days after the envenomation . the prompt administration of specific treatment was important for the favorable outcomes observed .

holotype : nhrm = nrm . according to andersson 1899 : 27 , there are two jars labeled as crotalus horridus , one of which contains a head in rather bad condition which does not belong to any crotalus and " possibly it is the head of a lachesis mutus . " ( mcdiarmid et al . 1999 ) ; type unknown fide peters 1960 . holotype : zsm , uncatalogued specimen ( s ) ( lost ) , “habitat non rarus in brasiliae sylvis humidis ac densis sub arborum fronde delapsa” [ brazil ] according to the original description and vanzolini ( 1981 ) , collected by spix and martius expedition to brazil , 1817 - 1820 [ surucucu ]

/ signs and symptoms / the symptoms and signs of envenoming / by a lachesis muta / ( local swelling , blistering , bruising , and necrosis with coagulopathy , spontaneous systemic bleeding , shock , and renal failure ) may be confused with those caused by other pitvipers . however , a distinctive syndrome has been described in a proportion of cases . there is early nausea , abdominal colic , repeated vomiting , and watery diarrhea with profuse sweating . . . . vomiting , severe abdominal colic , profuse diarrhea , hypotension , bradycardia , impaired consciousness , and other manifestations of shock may develop as soon as 15 minutes after the bite , while local effects of envenoming may leave permanent impairment .

in the state of amazonas and in areas nearby manaus , the snakes responsible for the majority of accidents are bothrops atrox and lachesis muta muta , with a percentage of confirmed species of 76 % and 17 % , respectively . frequently , in the absence of the laquetic and bothropic - laquetic antivenoms , the instituto de medicina tropical de manaus ( imtm ) has been using bothropic antivenom in the treatment of laquetic accident . in this paper is related a case of accident caused by l . muta muta ; the patient was treated with bothropic antivenom , and after received twenty ampules of this antivenom , maintained blood incoagulability until the 13th day after the accident . experiments to obtain the potency of the bothropic antivenom for the coagulant and hemorrhagic activities have been done , using bothrops atrox venom as control . the results showed that the potency of the antivenom for the hemorrhagic activity was similar , and the potency for the coagulant activity for the l . m . muta venom was 9 . 2 times minor than that for b . atrox . the antibodies titers from three different lots of bothropic antivenom varied for the l . m . muta venom , and were constant for the b . atrox venom . due to the inefficiency of the bothropic antivenom on the neutralization of the coagulant activity for the l . m . muta venom , the use of bothropic antivenom is not recommended in the treatment of lachesis muta muta accidents .

figures 2 - 23 . map of south american distribution of l . muta muta and l . muta rhombeata . figure 2 shows the standard demographic arrangement of lachesis muta in south america , with l . muta muta occupying nearly all of the amazonian regions ; and the debated subspecies , l . muta rhombeata restricted to brazil ' s atlantic forest belt . figure 23 shows my recommended revision of this distribution based on morphology : l . muta muta becomes restricted to trinidad , the guyana shield and contiguous regions ; and the range of l . muta rhombeata expanded to include the amazonian basin and contiguous areas . there is obviously a high degree of overlap , not unexpected in trinominal classification . this is a true clinal variation within a single species of snake , and subspecific classification best addresses these morphological differences accordingly .

/ other toxicity information / snake - venom proteins form multi - component defence systems by the recruitment and rapid evolution of nonvenomous proteins and hence serve as model systems to understand the structural modifications that result in toxicity . l - amino - acid oxidases ( laaos ) are encountered in a number of snake venoms and have been implicated in the inhibition of platelet aggregation , cytotoxicity , hemolysis , apoptosis and hemorrhage . an l - amino - acid oxidase from lachesis muta venom has been purified and crystallized . the crystals belonged to space group p21 , with unit - cell parameters a = 66 . 05 , b = 79 . 41 , c = 100 . 52 a / angstrom / , beta = 96 . 55 deg . the asymmetric unit contained two molecules and the structure has been determined and partially refined at 3 . 0 a / angstrom / resolution .

l . stenophrys venom proteins were separated by two - dimensional electrophoresis ( 2de ) using an ettan ipgphor iii instrument ( ge healthcare bio - sciences ab , uppsala , sweden ) . for isoelectric focusing , 300–350 μg of total venom proteins in 200 μl destreak rehydration solution ( ge healthcare bio - sciences ab , uppsala , sweden ) including 10 mm dtt and 0 . 5 % ipg buffer ph 3–10 nl ( ge healthcare bio - sciences ab , uppsala , sweden ) were loaded on a 11 cm ipg strip , ph 3–10 ( ge healthcare bio - sciences ab , uppsala , sweden ) and then focused using the following electrophoretic conditions : 500 v for 30 min , 1000 v for 30 min and 5000 v for 80 min . after isoelectric focusing , sds - page was performed under reducing conditions in 4–15 % criterion tgx precast 11 cm gels ( bio - rad , usa ) . an unstained protein molecular weight marker ( fermentas ) was included in the analysis . gels were stained using bio - safe coomassie stain ( bio - rad , usa ) or plusone silver staining kit ( ge healthcare ab , uppsala , sweden ) following the manufacturer´s instructions , and images were taken with chemidoc xrs imaging system ( biorad , usa ) . spot identification was done using the collaborative bioimage informatics platform icy [ 34 ] and quantified as relative density percentage using imagej software [ 35 ] .

/ other toxicity information / the kinetic behavior of a thrombin - like enzyme from lachesis muta muta venom has been studied with 13 tripeptidyl p - nitroanilide substrates . eight substrates were unprotected at the n terminus and were used for the regression analysis of the experimentally determined kinetic parameters 1 / km , kcat and kcat / km . the individual contribution of each amino acid side chain to the kinetic parameters was calculated . the amino acid sequence of the ideal substrate ( d - pro - leu - arg - pna ) was determined from a regression analysis for each kinetic parameter . this result was confirmed experimentally . the structural analysis of the tripeptides showed that the binding to the s3 sub - site had a small effect on km . the binding of l - leu to the s2 sub - site increased kcat without changing the value of km . the analysis of the kinetic parameters revealed that , in the binding of l - leu to the s2 sub - site , the enzyme bound the transition state configuration of the substrate / product transformation more tightly than that of the substrate .

96 - well plates ( dynatech immulon , alexandria , va ) were coated overnight at 4°c with lachesis venoms ( 0 . 5 μm / well ) in 0 . 1 m tris , 0 . 15 m nacl , ph 9 . 0 buffer . the plates were blocked for 1h with 2 % bovine serum albumin ( bsa ) in 20 mm phosphate , 135 mm nacl , ph 7 . 4 ( pbs ) at room temperature . purified antivenom immunoglobulins were serially diluted by a factor of 3 ( starting from a dilution of 1 / 500 ) in pbs containing 1 % bsa , and added to the wells for 1 h at room temperature . the plates were washed four times with washing buffer ( 50 mm tris , 150 mm nacl , 20 μm zncl 2 , 1 mm mgcl 2 , ph 7 . 4 ) , and anti - horse igg - phosphatase - conjugate ( sigma , st . louis , mo , usa ) , diluted 1 : 20 , 000 with pbs containing 1 % bsa , was added and incubated for 1 h at room temperature . the plates were washed and developed with p - nitrophenylphosphate in diethanolamine buffer ( 1 mm mgcl 2 , 90 mm diethanolamine , ph 9 . 8 ) . absorbance at 405 nm was recorded after 90 min using a microplate reader ( multiskan labsystems ltd . , helsinki , finland ) .

all the in vivo experiments were performed in cd - 1 mice , and the protocols were approved by the institutional committee for the care and use of laboratory animals ( cicua ) of the university of costa rica . lethality was assessed by the intraperitoneal route in 16–18 g mice and a challenge dose corresponded to 3 median lethal doses ( ld 50 ) was used for the neutralization tests [ 37 ] . an arbitrary level of 500 μl antivenom / mg venom was selected to evaluate the efficacy of antivenoms for neutralizing lethality . only this antivenom / venom ratio was used owing to the scarcity of some venoms and also for reducing the number of mice used . death of mice was recorded at 48 h . hemorrhagic activity was evaluated by using the rodent skin test using 18–20 g mice and a challenge venom dose corresponding to 10 minimum hemorrhagic doses ( mhd ) [ 41 ] . coagulant activity was assessed on citrated human plasma and the challenge dose used was 2 minimum coagulant doses ( mcd ) [ 40 ] . proteolytic activity was determined using azocasein ( sigma , usa ) as substrate , as described by gutiérrez et al . [ 42 ] . for neutralization tests , a challenge dose was selected , corresponding to the amount of venom that induced a change in absorbance of 0 . 75 at 450 nm . a summary of reference venom activities ( median lethal dose , minimum hemorrhagic dose , minimum coagulant dose and challenge dose for proteolytic activity ) of lachesis venoms are listed in table 1 .

snake species of the world : a taxonomic and geographic reference , vol . 1

disclaimer : itis taxonomy is based on the latest scientific consensus available , and is provided as a general reference source for interested parties . however , it is not a legal authority for statutory or regulatory purposes . while every effort has been made to provide the most reliable and up - to - date information available , ultimate legal requirements with respect to species are contained in provisions of treaties to which the united states is a party , wildlife statutes , regulations , and any applicable notices that have been published in the federal register . for further information on u . s . legal requirements with respect to protected taxa , please contact the u . s . fish and wildlife service .

the number of species increased from 10 , 711 to 10 , 793 , i . e . an increase of 82 species . 66 new species have been described , 9 species have been revalidated from synonymy and 16 subspecies were elevated to full species . . .

over the past 4 months , the number of species increased from 10 , 639 to 10 , 711 .

the number of species has grown from 10 , 544 in the may release to now 10 , 639 ( + 95 species ) .

overall , 212 new taxa have been added or changed their status or name .

the reptile database is a taxonomic database that provides basic information about all living reptile species , such as turtles , snakes , lizards , and crocodiles , as well as tuataras and amphisbaenians , but does not include dinosaurs .

currently there are more than 10 , 000 species and an additional 2 , 700 subspecies . this is making reptiles the largest vertebrate group after fish ( ~ 25 , 000 species ) and birds ( ~ 10 , 000 species ) , and significantly larger than mammals ( ~ 5 , 000 species ) or amphibians ( ~ 6 , 000 species ) .

the reptile database provides taxonomic information for the catalogue of life and the encyclopedia of life . our taxonomic information has also been used by genbank and many other resources and is the only comprehensive reptile database on the web .

the reptile database can be used to find all species within a certain geographic area ( e . g . all snakes of egypt ) . its collection of more than 2 , 500 images allow users to identify a species or at least get an idea how the species or genus may look like . more than 30 , 000 references provide a guide to further information .

neolamprologus niger is a species of cichlid endemic to lake tanganyika where it is only found along the northern shores .

it is a crevice-dweller and feeds on molluscs .

this species reaches a length of 9 centimetres ( 3.5 in ) tl .

it can also be found in the aquarium trade .

neolamprologus niger

neolamprologus niger <EOT> indeed - can anyone share a pdf of this paper ? based upon the abstract , it makes one wonder if n . schreyeni will / is synonymized with n . niger ? ?

its lives in rocky shores , where it can be very abundant . in these areas several other rubble - dwellers are also abundant . it appears to share the same ecological niche as neolamprologus leleupi .

pronunciation : refer to our pronunciation key for an explanation of the phonetic symbols .

habitat : this is the primary location where the cichlid is found and is a generalization . this does not mean a fish cannot be found in other habitats .

diet : many cichlids specialize in eating one type of food ; notwithstanding , some of these specialized feeders are flexible and can be opportunistic feeders .

temperament : this describes the overall demeanor of a cichlid toward other tankmates that are of a different species . consider that there is variability in temperament due to various factors , including aquarium size , tankmates of similar appearance , stocking levels , and order of introduction . there may even be some variability among individual specimens .

conspecific temperament : this describes the overall demeanor of a cichlid toward other tank - mates of the same species . consider that there is variability in temperament due to such factors as aquarium size , stocking levels and order of introduction . there may even be some variability among individual specimens .

maximum size : this is in regards to total length ( including the tail ) of typical aquarium specimens . wild specimens may not attain this size , or may in fact grow larger than aquarium raised individuals due to various factors . also consider that this is the typical maximum size and there are exceptional individuals that will exceed it .

difficulty : this measure is a relative value , comparing a single species against all other cichlids . this only accounts for maintanence in the aquarium and not breeding considerations . 1 = easy and forgiving , 5 = extremely challenging .
