Snake Genera

picture info	Snake Genera List of reptile genera lists the vertebrate class of reptiles by living genus, spanning two subclasses. Subclass Anapsida Order Testudinata (turtles) Turtles are reptiles of the order Testudines characterized by a special bony or cartilaginous shell developed from their ribs and acting as a shield.

picture info	Vertebrate Vertebrates () are animals with a vertebral column (backbone or spine), and a cranium, or skull. The vertebral column surrounds and protects the spinal cord, while the cranium protects the brain. The vertebrates make up the subphylum Vertebrata with some 65,000 species, by far the largest ranked grouping in the phylum Chordata. The vertebrates include mammals, birds, amphibians, and various classes of fish and reptiles. The fish include the jawless Agnatha, and the jawed Gnathostomata. The jawed fish include both the Chondrichthyes, cartilaginous fish and the Osteichthyes, bony fish. Bony fish include the Sarcopterygii, lobe-finned fish, which gave rise to the tetrapods, the animals with four limbs. Despite their success, vertebrates still only make up less than five percent of all described animal species. The first vertebrates appeared in the Cambrian explosion some 518 million years ago. Jawed vertebrates evolved in the Ordovician, followed by bony fishes in the Devonian. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Madagascan Big-headed Turtle The Madagascan big-headed turtle (''Erymnochelys madagascariensis'') is a turtle native to the waters of permanent slow moving rivers and lakes in western Madagascar. These turtles are critically endangered and have been evaluated to be the most endangered turtle in the world by a 2018 review. Due to its ancient origins and threatened status, it is ranked as #1 on the EDGE of Existence programme's list of priority reptiles. Taxonomy It is a highly evolutionary distinctive species, the only member of the ancient family Podocnemidae found outside of South America. It diverged from its closest living relative, ''Podocnemis'', during the Late Cretaceous, about 78 million years ago. Fossils of podocnemid turtles that are suggested to be closely related to ''Erymnochelys'' belonging to the same tribe Erymnochelyini, are known from the Cenozoic of Africa and Europe, with the youngest remains of turtles belonging to Erymnochelyini in mainland Africa dating to the Pliocene.

	Podocnemididae Podocnemididae is a family of pleurodire (side-necked) turtles, once widely distributed. Most of its 41 genera and 57 species are now extinct. Seven of its eight surviving species are native to South America: the genus '' Peltocephalus'', with two species, only one of which is extant (''P. dumerilianus'', the Big-headed Amazon River turtle); and the genus ''Podocnemis'', with six living species of South American side-necked river turtles and four extinct. There is also one genus native to Madagascar: '' Erymnochelys'', the Madagascan big-headed turtle, whose single species ''E. madagascariensis''. Like other pleurodire turtles, podocs have a "side-necked" defensive posture, turning the head sideways to hide it under the shell. Another characteristic of pleurodires is that the pelvis is fused to the shell which prevents pelvic motion, making it difficult to walk on land. Podocnemididae turtles live in aquatic environments and have shells streamlined to aid in swimming. The family ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Pelusios ''Pelusios'' is a genus of African side-necked turtles. With 17 described species, it is one of the most diverse genera of the turtle order (Testudines). Etymology The scientific name ''Pelusios'' is derived from the Greek word pēlos, which means "mud" or "clay", and this is reflected by the turtles living in streams and rivers with a muddy bottom. Common names Common names for the genus ''Pelusios'' include hinged terrapins, African mud turtles, and mud terrapins. Taxonomy Several species have been described, with probably numerous undescribed species. The taxonomy of the genus is very confused, as these species show many local variations. Certain species, in isolated areas or with reduced populations, need to be observed as they face a distinct extinction possibility given the significant number collected by native people. Geographic range They are found throughout Sub-Saharan Africa, Madagascar, São Tomé, and the Seychelles islands. They have also been introduced on ...
