Chelydra
''Chelydra'' is one of the two extant taxon, extant genus, genera of the snapping turtle family, Chelydridae, the other being ''Macrochelys'', the much larger alligator snapping turtle. The snapping turtles are native to the Americas, with ''Chelydra'' having three species, one in North America and two in Central America, one of which is also found in northwestern South America. Species The genus ''Chelydra'' has the following species: * ''Chelydra acutirostris'' (Wilhelm Peters, W. Peters, 1862) – South American snapping turtle * ''Chelydra rossignonii'' (Marie Firmin Bocourt, Bocourt, 1868) – Central American snapping turtle * ''Chelydra serpentina'' (Carl Linnaeus, Linnaeus, 10th edition of Systema Naturae, 1758) – common snapping turtle (North America) * ''Chelydra floridana''† * ''Chelydra laticarinata''† * ''Chelydra sculpta''† The three extant ''Chelydra'' species were once all considered to be several subspecies of ''Chelydra serpentina'', along with a fourth ...

Chelydra Serpentina
The common snapping turtle (''Chelydra serpentina'') is a species of large freshwater turtle in the Family (biology), family Chelydridae. Its natural range extends from southeastern Canada, southwest to the edge of the Rocky Mountains, as far east as Nova Scotia and Florida. The present-day ''Chelydra serpentina'' population in the Middle Rio Grande suggests that the common snapping turtle has been present in this drainage since at least the seventeenth century and is likely native. The three species of ''Chelydra'' and the larger alligator snapping turtles (genus ''Macrochelys'') are the only extant Chelydridae, chelydrids, a family now restricted to the Americas. The common snapping turtle, as its name implies, is the most widespread. The common snapping turtle is noted for its combative disposition when out of the water with its powerful beak-like jaws, and highly mobile head and neck (hence the Specific name (zoology), specific epithet ''serpentina'', meaning "snake-like").

Central American Snapping Turtle
The Central American snapping turtle (''Chelydra rossignonii''), also known commonly as the Mexican snapping turtle and the Yucatán snapping turtle, is a species of turtle in the family Chelydridae. The species is endemic to Central America and Mexico. Taxonomy ''C. rossignonii'' was formerly considered a subspecies of '' C. serpentina'', the common snapping turtle; it earned full species classification when scientists noted several genetic and morphological differences between the two species' skulls. Etymology The specific name, ''rossignonii'', is in honor of French-born coffee grower Jules Rossignon.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Chelydra rossignoni'', p. 226). Subspecies There are no recognized subspecies of ''C. rossignonii''. Description ''C. rossignonii'' has a big head, lengthy tail, pointed snout, and a coarse carapace with three easily ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chelydra Acutirostris
The South American snapping turtle (''Chelydra acutirostris'') is a species of turtle in the family Chelydridae. This species, which is endemic to Central and northwestern South America, was previously considered a subspecies of ''Chelydra serpentina''. Its restricted range in South America reflects its recent arrival there as part of the Great American Interchange. Geographic range ''Chelydra acutirostris'' is found in Honduras, Nicaragua, Costa Rica, Panama, Colombia, Ecuador and Peru Peru, officially the Republic of Peru, is a country in western South America. It is bordered in the north by Ecuador and Colombia, in the east by Brazil, in the southeast by Bolivia, in the south by Chile, and in the south and west by the Pac ....

Chelydridae
The Chelydridae is a family of turtles that has seven extinct and two extant genera. The extant genera are the snapping turtles, ''Chelydra'' and '' Macrochelys''. Both are endemic to the Western Hemisphere. The extinct genera are '' Acherontemys'', '' Chelydrops'', '' Chelydropsis'', '' Emarginachelys'', '' Macrocephalochelys'', '' Planiplastron'', and '' Protochelydra''. Fossil history The Chelydridae have a long fossil history, with extinct species reported from North America as well as all over Asia and Europe, far outside their present range. The earliest described chelydrid is '' Emarginachelys cretacea'', known from well-preserved fossils from the Maastrichtian stage of the Late Cretaceous of Montana. Another well-preserved fossil chelydrid is the Late Paleocene '' Protochelydra zangerli'' from North Dakota. The carapace of ''P. zangerli'' is higher-domed than that of the recent ''Chelydra'', a trait conjectured to be associated with the coexistence of large, turtle-eatin ...
