After hatching from the eggs, juvenile crayfishes (looking alike the adults) will stay attached to the underside of the female’s abdomen for several days, usually going through two or three molts as body size initially increases. SIZE: Adult body length up to 6" in Kentucky (bottlebrush crayfish, Barbicambarus cornutus)Ĭrayfish begin their life as fertilized eggs attached to the underside of the female’s abdomen from early March to late May. During the molting process, crayfishes are very vulnerable to predation because they are soft and unable to move effectively: they find refuge under rocks, in woody debris, or in burrows. These structures will provide the important initial source of calcium used to harden the new exoskeleton. In the days leading up to molting, crayfishes begin to break down the calcium salts in their exoskeleton and store a small amount of them in small whitish dislike structures called gastroliths. The lives of crayfishes consist of a continuous process of shedding, or molting, their old exoskeleton, and growing and hardening the new exoskeleton (Figure 1).

The Astacidae is composed of approximately 13 species and is distributed in Europe, western Asia, and the extreme northwestern United States and southwestern Canada. The 530 species of crayfish recognized worldwide are distributed in three families: Astacidae, Cambaridae, and Parastacidae. Among the crustaceans, crayfish belong to the Order Decapoda, which also includes many familiar marine creatures, including lobsters, crabs, and shrimp. Within that Phylum, they belong to the Subclass Crustacea, which is the same group that sowbugs belong to.
