Crayfish have swimmerets on the abdomen.
Uropods help the crayfish to accomplish the life process, movement. They also help steer the crayfish into the correct direction.

The term for the crayfish's pinchers is chelae. The chelae are two pincher-like claws that can be found on the front of the crayfish's body and are used for hunting, defense, and helping the crayfish to move. The chelae are connected to a series of muscles and tendons, which allow them to open and close. The chelae are also covered in sensory hairs that help the crayfish detect its environment. They can be used to grab and hold onto food, as well as helping the crayfish to climb and dig.
