They do. Tagmosis is the specialization of parts, and crayfish have many appendages specialized for certain uses. The claws they have are specialized for grabbing food, cutting, and defending itself. There are small appendages around the mouth that are used to hold food while chewing. The four pairs of walking legs are used for walking as well as probing the surface they are walking on for food. In males, the copulatory swimmerets are specialized appendages used in reproduction. Their antennae are also specialized for sensing the world around them. The other swimmerets and the uropods are also specialized.
