Turtles. A turtle is an animal in armor. Much of its body lies within a protective shell, which has openings for the turtle's four chunky legs, short tail, and head. When danger threatens, many turtles pull legs, tail, and head into the shell.But unlike some animals that live in shells, such as hermit crabs and snails, a turtle cannot crawl out of its shell.he turtle's ribs are firmly fixed to the inside of its shell, so in order to breathe the turtle uses two special sets of muscles. One set pulls the other body organs away from the lungs, filling the lungs with air. Then a second set of muscles pulls the organs against the lungs, forcing the air out.
