Chela (organ)

A chela (/ˈkiːlə/), also named claw, nipper, or pincer, is a pincer-like organ terminating certain limbs of some arthropods.[1] The name comes from Greek (χηλή) through New Latin (chela). The plural form is chelae.[2] Legs bearing a chela are called chelipeds.[3] Another name is claw because most chelae are curved and have a sharp point like a claw.

Fiddler crab
Uca pugnax, like other members of the family Ocypodidae, have chelae of different sizes: a large left chela and a small right chela.

Pincer (biology)

A pincer is the part of an arthropod that enables it to carry loads, to defend against other creatures, or to attack prey. In insects, the pincers are usually part of the creature's mandible, and often venom or acid can be injected through the pincer into an enemy during a pincer strike.

Some arthropods such as crabs, lobsters, and scorpions possess pincers in the form of chelae at the ends of their front limbs (pedipalps), to assist in feeding, defence or even courtship.
