Does a crab have legs? How many legs?

Crabs have eight legs, that is, their eight walking feet. The eight legs are evenly distributed on both sides of their body, four on each side.

In addition to walking feet, crabs also have two chela feet, the main role is to dig holes, defense, attack and so on. Since the main function is not movement, these two chelicerae cannot be counted as their legs.
