How many tortoise species are there




















The red-bellied short-necked turtle Emydura subglobosa has been nicknamed the painted terrapin because it has a bright-red belly when it's young, then the vivid hue fades to orange or yellow as it ages. Native to tropical Australia and New Guinea, it grows to be about 10 inches long and is popular as a pet. The spiny softshell turtle Apalone spinifera is one of the largest freshwater turtles found in North America — females can grow a carapace of up to 19 inches long.

Found from Canada to Mexico, these turtles can live to be 50 years old and don't reach sexual maturity until eight to 10 years of age. The species gets its name from the small spines that project from the upper front portion of its carapace, making it look even more like its late dinosaur relatives.

The Roti Island snake-necked turtle Chelodina mccordi is one of the stranger looking turtle species, with its namesake elongated neck. Its most distinguishing feature can reach between seven and nine inches long, about the length of its carapace taking up half of its body length. But this species is critically endangered. Its desirability in the pet trade has led to serious declines of wild populations.

The two or three populations left are located in a tiny area of Rote Island, Indonesia, and they are still often illegally captured for trade. Native to Madagascar, the radiated tortoise Astrochelys radiata is distinguished by its high-domed shell featuring yellow lines fanning out from the center of each plate hence the name "radiated". In addition to its geometric aesthetic, the radiated tortoise can live especially long — the oldest on record is Tu'i Malila, who lived to be an estimated years old.

The species is critically endangered due to habitat loss, poaching, and collection for the pet trade. Not only is the leatherback Dermochelys coriacea the largest of all sea turtles, it also dives the deepest and travels the farthest.

Unlike other sea turtles, it has no scales or hard shell; instead, its back is covered with rubbery skin and oily flesh — thought to be unchanged since the dinosaur era.

Leatherbacks are real tough guys, too, apt to chase away sharks and other predators. And yet, like most sea turtle species, this one is threatened by fishing and plastic pollution , currently listed on the IUCN Red List as a vulnerable species. Cantor's giant softshell turtle Pelochelys cantorii is called "giant" because it can be more than six feet long.

Its broad head and flattened shell helps to camouflage it with the sand as it waits, motionless, at the bottom of freshwater rivers and streams, for a chance to ambush its prey. It surfaces only twice a day to breathe. The peculiar-looking turtle was only recently rediscovered in Cambodia in It's an endangered species.

The African spurred tortoise Geochelone sulcata has impressive "spurs" along its forelegs. Found along the southern edge of the Sahara desert, it is the third largest tortoise species in the world, and the largest mainland tortoise both the larger Galapagos tortoise and Aldabra giant tortoise are island dwellers. They can grow to two to three feet long over their to year lifespan.

Because they're popular in the pet trade, they are often removed from the wild and are, as a result, listed as a species vulnerable to extinction. The Indian flapshell turtle Lissemys punctata has many folds of skin that cover its limbs when it retreats into its shell and are thought to help protect it from predators.
