All turtles, tortoises, and terrapins are reptiles. Scientists often refer to them as chelonians, because they are in the taxonomic order called Chelonia (from the Greek word for tortoise). They all have scales, lay eggs, and are ectothermic; they vary in size from fitting in your hand to about 1,800 pounds (817 kilograms). Chelonians live everywhere from deserts to oceans to backyard creeks.
Tortoise: A land-dweller that eats low-growing shrubs, grasses, and even cactus. Tortoises do not have webbed feet; their feet are round and stumpy for walking on land. Tortoises that live in hot, dry habitats use their strong forelimbs to dig burrows. Then, when it’s too hot in the sun, they slip underground.
Terrapin:Spends its time both on land and in water, but it always lives near water, along rivers, ponds, and lakes. Terrapins are often found in brackish, swampy areas. The word “terrapin” comes from an Algonquian word for turtle.
