Crabs are arthropods that live in the ocean and freshwater, and their bodies take on a rounded and flattened shape, with a hard shell on their backs and a pair of curved chelicerae on their abdomens. The crabs' chelipeds are their most distinctive part and the main tool they use for feeding and defense. Among the crabs' chelipeds, the most unique is their pincers, which are often called crab pincers.

Structure of crab pincers

The crab's chelicerae consist of two parts, the large pincer and the small pincer. The large pincer is usually thicker than the small pincer and their jaws are wider. The small pincers, on the other hand, are more slender than the large pincers and their jaws are sharper. Inside the crab's chelipeds are special structures, such as muscles, ligaments and nerves, that work in concert to enable the crab to use their chelipeds for efficient predation and defense.

Functions of crab pincers

The pincers of crabs are their main weapons, which they can use to hunt for food, defend themselves against enemies, protect themselves and mate. Often stronger than their bodies, crabs' pincers can hold objects of all sizes with their pincers, and can even hold the chelicerae of other crabs. The crab's pincers can also be used for defense against natural predators, such as starfish, octopus, and sharks. When encountering an enemy, crabs will use their pincers to clamp down on the enemy's body, thus protecting their own lives.
