Many turtles have powerful jaws, with which they tear food and capture prey. Legs and feet. A turtle's legs and feet vary according to the habitat of the species. Land turtles, particularly tortoises, have heavy, short, clublike legs and feet. Most freshwater turtles have longer legs and webbed feet.
Sea turtles have legs shaped like long paddles, with flippers instead of feet.
The hip bones and shoulder bones of the turtles, unlike those of any other animal, are inside the ribcage. This unusual feature enables most kinds of turtles to pull their legs inside their shell. The species that are unable to withdraw their legs cannot do so because the shell is too small. Turtles have a well-developed sense of sight and of touch. Scientific experiments indicate that they also have a good sense of smell, at least for nearby objects.
