Wild animals
Can turtles leave their shells?
As most people know, turtles are the slowest creatures in the world. This isn't entirely true, as marine animals of this species can reach speeds of over 30 km/h; only land-dwelling turtles are slow. Moreover, the heavier the shell, the slower the animal's speed. If the shell hinders speed, wouldn't it be logical to get rid of it? Could turtles survive without it?
