Are you wondering where do hermit crabs live and how long do hermit crabs live? This guide will help you understand more details about hermit crabs. Crabs have been around since at least 200 million years ago; a land or water-dwelling animal with a short, flat, nearly circular body.
The crab is a crustacean, distinguished from lobsters, shrimps and other crustaceans by the shape of its body. The head and thorax are fused together to form a shell or carapace and the small abdomen (tail) is folded under the shell. Crabs have 10 legs, the front pair sometimes growing into large claws while ocean dwelling crabs that swim have only one pair of legs adopted into paddles.
