if you have ever cleaned a whole crab im sure you noticed a series of spongy wedge shaped organs under the shell along the sides near where the legs attach. these are the crabs gills, which allow it to extract oxygen (breathe) from water.
in addition to the gills, a crab has a number of other adaptations making it well suited for an aquatic environment.
