They lives in a crab burrows.
no they do not!
a shell...
They all need food,water&shelter
all the animals in the water do! they use them for shelter to hide from predators . animals that might do this are blue crabs!
well i have 2 hermit crabs named charlie and kiwi, and i have tried everything to try and get them into the shelter... i have tried containers, rock shelters, small plant and even the old peels off of an orange. they never seemed to like them... until i tried a cocoa nut hut!!! you can buy them from pet stores and they come in all sizes, they are half of a cocoa nut with a little door cut in it my crabs love it and it also keeps them warm
They both thrive, reproduce, grow, and develop in water.
Actually They are called rock crabs, Because they are Crabs born with rocks on there back -Actually, there are lots of types of crabs that live on rocky platforms in intertidal beach zones that are NOT born with rocks on their back, but shelter under rocks to avoid wind, heat loss, protection from predators etc. If you happen to be on a beach you can lift a rock that is inhabited by crabs and can watch them scurry away and slip under another rock. Rocks do not fit perfectly to the ground, so there is a lot of space for a thin crab to fit under.
A hermit crab needs food, water, a spray bottle to spray the ground, and a shelter their might be other things but that is all i know.
Food, Water, Shelter, Air. If your talking about hermit crabs, they need humidity, a certain temp, DISTILLED water, and soo much more!
Some types of crabs I know of are fiddler crabs, hermit crabs and horseshoe crabs.
Mostly asian shore crabs, Mud crabs,Rock crabs, Donut Crabs and Spider Crabs. I believe there are no freshwater varieties.
rock crabs are type of crabs.
