grabbing food or snapping at things
Chelipeds are specialized appendages found in certain crustaceans, such as crabs and lobsters. Their primary function is to grasp and manipulate objects, serving as pincers for feeding, defense, and communication. In many species, chelipeds also play a significant role in mating displays and territorial displays among males. Additionally, they help in foraging and capturing prey.
Chelipeds
A cheliped is not a separate body part but rather a term used to describe a specific type of limb in crustaceans, such as crabs and lobsters. Each crustacean typically has one pair of chelipeds, which means they have two chelipeds in total. In addition to chelipeds, crustaceans have other legs, with most having a total of ten legs, including walking legs and the two chelipeds.
Chelipeds are the large, often clawed appendages found in crustaceans, such as crabs and lobsters. Their primary functions include grasping and manipulating food, defending against predators, and engaging in competitive displays or mating rituals. Additionally, chelipeds can assist in locomotion and help the animal interact with its environment. Overall, they play a crucial role in the survival and behavior of these animals.
It's the grasping claws on its front limbs
The chelipeds aren't really related to the movement of the crayfish itself, unconciously these appendages might move the crayfish, but really the chelipeds are a form of defense and used for food handling, much like the one big claw of the "Fiddler" Crab. INother words, the chelipeds are the two big dangrous looking claws of the crayfish.

Chelipeds are the main grasping claws of crustaceans. The two biggest claws on lobsters, crabs etc.
A crab has four pairs of legs and a pair of chelipeds (claws).

crabs have 8 legs, 2 pincers:Although crabs come in a variety of shapes and sizes they all have the same general body plan. All crabs have one pair of chelipeds and four pairs of walking legs. Also referred to as claws, nippers or pincers, the chelipeds are the first pair of legs on a crab and their most distinguishing structure. Chelipeds are used for holding and carrying food, digging, cracking open shells and warning off would be attackers. The carapace is the hard cover or exoskeleton which protects the internal organs of the head, thorax and gills.
