There are more than 300 species of turtles in the world.
Turtle is often used for all turtles, tortoises, and terrapins since all turtles are part of the species testudine.
Unlike tortoises, though turtles are always aquatic, semi-aquatic or can live with a fair amount of water exposure.
Turtles can be very, very small or very large. The speckled padloper tortoise is 3 inches on average and only weighs a few ounces. The red-eared slider is a terrapin that averages 6-8 inches and can live twenty years or more. The leatherback sea turtle averages nearly 7 feet long and can weigh up to 2000 lbs which is more than many horses.

There is so much diversity within the turtle group that it is hard to even compare them all.
Most turtles don’t actually do that well when kept as pets simply because it is so difficult to create an ideal environment for them even if they are small.
They have very special temperature requirements, they do best with fresh foods, and they need plenty of room.
Turtles are usually sub-categorized into two sub-groups which include Cryptodira and Pleurodira.
The Cryptodira can usually retract their heads into their shells.
You can go much further when defining turtles. For example, you could divide turtles as follows:
Even if you pick out a turtle from the above list, there may be many more turtles that fall into just that category.
Sea turtles can be broken into many different types.
Snapping turtles can be the more common type or the “alligator” type.
While it is fairly easy to point out an animal with the general characteristics of a turtle, really defining “turtle” is much more complex!
