Turtles live in an aquatic environment. The average turtle spends most of its life in oceans, lakes or rivers, and it has evolved adaptations that reflect this lifestyle (for example, webbed feet with which it can swim more easily and a streamlined body). Usually, turtles only venture onto dry land when it's time to lay eggs-and when the eggs hatch, the baby turtles head straight to the water.
Tortoises are primarily land-dwelling creatures. Because they don't have to be hydrodynamic, tortoises tend to be stumpier-looking than turtles, with stubby, strong legs and a more rounded body shape. Tortoises that live in hot climates usually stay underground during the day (remember, reptiles are cold-blooded and need to protect themselves from extreme temperatures).
