A Complete List of the Different Types of Turtles With Pictures. As we mentioned earlier, there exist more than 3. This difference between the largest and the smallest species of turtles speaks in volumes about the great deal of diversity in this reptile family. With time, evolution has created an ever- increasingly diverse range of turtle species, each with its own special characteristics. The fact that there are more than 3. Such ignorance about the different types of turtles is surprising, considering that these reptiles have existed on the planet for more than 2. Upper Triassic. In what follows, you will find small factual portraits of some turtle species.
Turtle or Tortoise. Usually, the word 'turtle' is used for the members of this reptile family found in the oceans, while those found on the land are termed 'tortoises'.

From a layman's point of view, terms like order, sub- order, genus, binomial name, etc., are bound to cause confusion. In order to make it simple, each of the existing families of turtles are grouped into different types - such as the snapping turtles, sea turtles, true tortoises, mud turtles, river turtles, soft- shell turtles, side- necked turtles, etc. Given below are the details of this classification of different turtle species on the planet.
Snapping Turtles. Snapping turtles are the species of turtles which belong to family Chelydridae. This family of turtles consists two species in monotypic genera - the 'common snapping turtle' and the 'alligator snapping turtle', with their population spanning across the continents of North America and South America, besides some parts of Asia. Genus Chelydra. Common snapping turtle (Chelydra serpentina)Geographical Range: Canada, United States and Mexico. Conservation Status: Least Concerned. Genus Macrochelys.
Alligator snapping turtle (Macrochelys temminckii)Geographical Range: Southern United States. Conservation Status: Vulnerable. Sea Turtles. Sea turtles are the turtles belonging to family Cheloniidae and family Dermochelyidae - which together consist seven extant species of these marine reptiles. These are the turtle species which most of the people picture when they hear the word 'turtle'. While the Cheloniidae family consists four monotypic genera and one polytypic genera, the Dermochelyidae family is made up of a single monotypic genera - with the leatherback sea turtle as the lone member of the family. Sea turtles are found in all the oceans of the world, except for the Arctic ocean. Genus Caretta. Loggerhead sea turtle (Caretta caretta)Geographical Range: Distributed throughout the world.
Conservation Status: Endangered. Genus Chelonia. Green sea turtle (Chelonia mydas)Geographical Range: Tropical and subtropical seas of the world. Conservation Status: Endangered. Genus Eretmochelys. Hawksbill sea turtle (Eretmochelys imbricata)Geographical Range: Distributed throughout the world.

The big- headed turtle was grouped with the snapping turtles previously owing to its resemblance to them, but this placement was reconsidered as eventually it became clear that the resemblance is trivial. Genus Platysternon. Big- headed turtle (Platysternon megacephalum)Geographical Range: China, Laos, Myanmar, Thailand, and Vietnam.
Conservation Status: Endangered. Pond Turtles and Marsh Turtles. Those species of turtles which are found in ponds and marshes across the world come together to form the Emydidae family of turtles. This group is made up of around 5. Western Hemisphere.
