| characterization of serum phospholipase a(2) activity in three diverse species of west african crocodiles. | secretory phospholipase a(2), an enzyme that exhibits substantial immunological activity, was measured in the serum of three species of diverse west african crocodiles. incubation of different volumes of crocodile serum with bacteria labeled with a fluorescent fatty acid in the sn-2 position of membrane lipids resulted in a volume-dependent liberation of fluorescent probe. serum from the nile crocodile (crocodylus niloticus) exhibited slightly higher activity than that of the slender-snouted cro ... | 2011 | 22110960 |
| feeding mechanics in spinosaurid theropods and extant crocodilians. | a number of extant and extinct archosaurs evolved an elongate, narrow rostrum. this longirostrine condition has been associated with a diet comprising a higher proportion of fish and smaller prey items compared to taxa with broader, more robust snouts. the evolution of longirostrine morphology and a bulbous anterior rosette of premaxillary teeth also occurs in the spinosaurid theropod dinosaurs, leading to suggestions that at least some members of this clade also had a diet comprising a notable ... | 2013 | 23724135 |
| check-list of the pentastomid parasites crocodilians and freshwater chelonians. | based on published records and own data a summary is given of the geographical distribution of the currently known species of pentastomid parasites infecting crocodiles and alligators, as well as freshwater chelonians. a brief generic diagnosis is provided for each genus. fourteen out of the currently 23 living crocodilian species have been recorded as being host to one or more pentastomes. out of the 32 pentastome species six are considered species inquirendae. presently, six genera of crocodil ... | 2006 | 16715876 |
| the complete mitochondrial genome of salt-water crocodile (crocodylus porosus) and phylogeny of crocodilians. | the nucleotide sequence of the complete mitochondrial dna (mtdna) molecule of the salt-water crocodile (crocodylus porosus) was determined in this article. the molecule is 16,917 base pairs (bp) in length, and codes for 22 trnas, 13 protein-coding genes, 2 rrnas, as well as a control region (d-loop), as is characteristic for mitochondrial genomes of other metazoans. the gene order conforms to that of other crocodilians sequenced, but the arrangement of some trna genes differs from other vertebra ... | 2007 | 17469784 |
| comparative functional morphology of the masticatory apparatus in the long-snouted crocodiles. | the masticatory muscles and their related structures of the skull were observed in the indian gavial (gavialis gangeticus), the false gavial (tomistoma schlegelii), and the african slender-snouted crocodile (mecistops cataphractus) to detail some morphological differences in comparison with the other crocodile species, and to compare and elucidate the functional strategy of themasticatory apparatus in these long-snouted species. the musculus pterygoideus posterior was relatively smaller in the t ... | 2002 | 12196262 |
| health survey including selected blood parameters in the african slender snouted crocodile (mecistops cataphractus) at the abidjan zoo in côte d'ivoire. | the zoo national d'abidjan (abidjan zoo) in côte d'ivoire, west africa, holds the world's largest captive population of african slender-snouted crocodiles (mecistops cataphractus, formerly crocodylus cataphractus), at 36 adults, 16 yearlings, and 23 hatchlings. twelve yearling and 12 adult slender-snouted crocodiles at the abidjan zoo were restrained for physical exam, body condition scoring, and venipuncture in september 2015. blood samples collected from the supravertebral venous sinus were an ... | 2017 | 28749270 |
| rigorous approaches to species delimitation have significant implications for african crocodilian systematics and conservation. | accurate species delimitation is a central assumption of biology that, in groups such as the crocodylia, is often hindered by highly conserved morphology and frequent introgression. in africa, crocodilian systematics has been hampered by complex regional biogeography and confounded taxonomic history. we used rigorous molecular and morphological species delimitation methods to test the hypothesis that the slender-snouted crocodile (mecistops cataphractus) is composed of multiple species correspon ... | 2014 | 24335982 |
| the gavialis-tomistoma debate: the contribution of skull ontogenetic allometry and growth trajectories to the study of crocodylian relationships. | the phylogenetic placement of tomistoma and gavialis crocodiles depends largely upon whether molecular or morphological data are utilized. molecular analyses consider them as sister taxa, whereas morphological/paleontological analyses set gavialis apart from tomistoma and other crocodylian species. here skull allometric trajectories of tomistoma and gavialis were contrasted with those of two longirostral crocodylian taxa, crocodylus acutus and mecistops cataphractus, to examine similarities in g ... | 2011 | 21040423 |
| are crocodiles really monophyletic?--evidence for subdivisions from sequence and morphological data. | recently, the phylogenetic placement of the african slender snouted crocodile, crocodylus cataphractus, has come under scrutiny and herein we address this issue using molecular and morphological techniques. although it is often recognized as being a "basal" form, morphological studies have traditionally placed c. cataphractus within the genus crocodylus, while molecular studies have suggested that c. cataphractus is very distinct from other crocodylus. to address the relationship of this species ... | 2006 | 16495085 |
