These reptiles are fun creatures who carry their home and protection with them at all times. These shelled critters have the ability to hide their heads when attacked by any mean predator that comes along. But this special feature doesn't come without its drawbacks, because to carry around this defense system can make them slow. So slow, in fact, that rabbits think they can always outrun these guys. But one thing turtles can say that rabbits can't is that they've been in space. Which happened back in 1968 when two turtles were launched into orbit and came back after a week just fine.
