The Lobster’s Tiny Cousin

Also known as crawfish or crawdad, crayfish is the common name given to over 500 different species of crustaceans within the families Austroastracidae, Astacidae, and Parastacidae, and half of which all occur in North America. Mostly all crayfish live in freshwater, with only a few species living in brackish or saltwater. Close cousins to the lobster, they are easily identifiable by their joined head and thorax, segmented body, and large claws on the front pair of legs, making them look like baby lobsters.
