Crabs – A group of crustaceans consisting of nearly 7 thousand species. Crabs have a characteristic body shape with a thick exoskeleton. Many crabs, like the ones in our collection, are relatively agile and fast swimmers, able to move in all directions. They are found in all of the world’s oceans, in freshwater, and even on land. Their diets vary but in general, they feed on plant and animal material found on the bottom of bodies of water. They are an important part of the fishing industry of several countries and are prized for their pleasant taste.
