How Many Legs Do Crayfish Have?

Crayfish have a total of 10 legs, comprised of five pairs. Four of these pairs are referred to as “walking legs,” while the fifth pair consists of “chelipeds” or pinchers.

As members of the phylum Arthropoda, crayfish have jointed legs, exoskeletons, and segmented bodies. Except for the larger pinchers, their legs are long, thin, and composed of several segments. The external skeleton is composed of chitin, a material similar to human fingernails that is rich in calcium. There are two major bodily sections. Following the cephalothorax in the front comes the abdomen. The initial section is separated into the head and torso. The abdomen, sometimes known as the tail, consists of seven distinct portions.
