How does the shape of a crabs abdomen differ from that of a crayfish?

Answer 1

im not sure what the exact answer is but crabs aren't mammals. They are both crustaceans, class malacostraca

Crabs and Crayfishes both belong to phylum arthropoda and the same class known as Crustacea (hard exoskeletons). The only difference between them can be that crabs are a bigger version of crayfishes and they are able to live both in water and land but crayfishes are only marine.

Hope that helps

Answer 2

The abdomen of a crayfish or shrimp is long and slender. It tapers from the body down to a pointed tail with a fan-shaped swimming part at the very end. The abdomen of a crab is flat, and the crab keeps it tucked underneath its body. Most people do not realize that a crab even has a tail-part because it is folded up underneath the thick body.
