Turtle Facts will help you to learn about the different species of turtles, where they come from, and many other interesting things. Here's everything you need to know.

Turtle Facts -- Facts

1. Species:

   There are about 250 species of turtles in the world. Some live only on land, some only in water, and others live equally in both environments. All turtles are cold-blooded, but are specially-adapted to the habitat in which they live.

2. Size:

   The smallest turtles are the Speckled Cape Padloper Tortoise and the endangered Bog Turtle, which are both under four inches when full-grown. The largest tortoise is the Galapagos Tortoise, which can grow up to 6 feet long and weigh over 500 pounds.

3. Life Span:

   The oldest turtles are Galapagos Tortoises, which live to be well over 100 years old. Even smaller species of turtle have been known to live for up to 40 years.

4. Origins:

   Turtles have been on earth for over 200 million years.

5. Physical Traits:

   When people think of turtles, they generally envision a hard shell into which the turtle can withdraw its head and legs. This is common of many turtles, but not all. Some sea turtles cannot withdraw into their shells. Most land turtles have a high, domed shell, while the shells of water turtles are more flat and streamlined, to make it easier to swim.

6. Temperament:

   Most turtles kept as pets are fairly gentle and docile. However, the snapping turtle is aggressive, especially when food is involved.

7. Trainability:

   Turtles can be trained to eat out of your hand, and can even be trained to do some kinds of tricks.

Turtle Facts -- How to Choose

1. What to Look for:

   The healthiest turtles are available from breeders of that specific type of turtle, as breeders have the most experience. Generally, though, a healthy turtle will have clear and alert eyes, a healthy-looking shell and skin, and will be active.

2. Supplies:

   The turtle's aquarium should have a land area, as well as a separate area for swimming. You will need two sources of heat: a heating pad under the tank and a light on one side of the tank for basking.
