Lobsters And Crayfish

This group gathers Crustaceans subcategory members belonging to the lobsters and crayfish, decapod crustaceans with an elongated body and a muscular, fan-tipped tail used to propel the animal backward in a rapid escape flip when startled. Marine lobsters such as the American lobster and the spiny lobsters carry a pair of large, often unequal front claws used for crushing and cutting prey, while their close freshwater relatives, the crayfish, are generally much smaller and live in streams, ponds and burrows dug into wet soil across every continent except Africa and Antarctica. Both groups are omnivorous scavengers that will eat nearly anything they can catch or find, molt their entire hard exoskeleton periodically to grow larger, and are prized around the world as food, supporting major commercial fisheries and, for crayfish, a long tradition of backyard boils in several regions.
