The following diagrams include the explained anatomy of a crayfish. This collection of printable crayfish diagram shows a range of organs of the crustacean. Crayfish are also known as crawdads, crawfish, and freshwater lobsters. They are closely related to lobsters, crabs, and shrimp. Check out the diagram in the following list to know more about the crayfish!
As you can notice in the first image of the crayfish diagram, this crustacean has 8 jointed walking legs, a segmented body, 2 pairs of sensory antennae, and compound eyes. It has 2 large pincers or claws called chelipeds. Using gills, a crayfish breathes oxygen that is dissolved in water. 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 those body structures in the diagrams below.
As shown in the diagram, the part of the exoskeleton that covers the cephalothorax is called the carapace. The abdomen is located behind the cephalothorax and consists of six clearly divided segments. The crayfish also has two sets of antennas that help them gather information about their environment. Crayfish can either walk on the bottom of the ocean or lake or use their uropods to propel them through the water.
