Freshwater Crayfish Diagram

Crayfish are crustaceans that are closely related to lobsters, crabs, and shrimp. There are about 150 crayfish species in North America, and over 540 species worldwide. Crayfish live in streams, rivers, swamps, ponds, and other freshwater habitats. Most crayfish are strictly aquatic but some live in semi-aquatic environments.  As you can notice in the crayfish diagram, crayfish have two main body areas: the cephalothorax, which consists of the head and upper body, and then the abdomen, which is clearly segmented. You can find appendages on both areas.

On the head, there are the eyes, antennae, and antennules, which look like much shorter antennae. A crayfish will use its antennae for touch, taste, and smell, and its antennules for balance, touch, and taste. We also find the mouth parts of the crayfish here. The mandibles are the crushing jaws, and two pairs of maxillae hold and tear solid food before it reaches the mouth. There’s yet another structure that helps with eating called the maxillipeds. These act like arms that hold food while the crayfish eats. The uropods and telson together make up the tail fan. The crayfish is able to move backwards by forcing water with its tail fan.
