Check whether it has webbed feet. Most people use the terms "tortoise" and "turtle" interchangeably. Tortoise breeds are generally land animals, only going into ponds or creeks to drink.

Look at the feet. Most types of tortoise have clawed front and rear feet to help them move better on land and to make burrows.

Freshwater turtles, such as snapping turtles and soft shell turtles, have webbed rear feet and clawed front feet.

Inspect the beak.

If it has a squared, blunt beak, it is a tortoise species. If it has a sharp pointy beak, it is a snapping turtle. If it has a long, pig-like snout, it is a soft shell turtle. A hooked beak similar to a bird of prey will likely belong to a box turtle.

Look at the tail. If the tail is long and has spikes, it is probably a snapping turtle. If the tail is short and stubby, it is more likely a land type of tortoise.

Check out the shell. Tortoise species identification is often easiest by looking at the shell.

If it appears soft and flat, it is a soft shell turtle, which will bite. If it has a line of ridges running the length of the shell that look like spikes, it is probably a snapping turtle, which will also bite.

If the shell looks more like a helmet-shaped dome, it is likely a benign box or painted turtle. A black shell with yellow markings means a spotted turtle. A brown or gray shell with growth rings on each section of shell is a wood turtle.

Check the markings. Turtles with red markings on the top or bottom of the shell as well as on the neck and legs are called painted turtles.

Turtles with yellow lines or stripes and no red markings are likely common map turtles. Turtles with red and orange markings near the eyes and yellowish stripes on the head and legs are red-eared sliders.
