Chela (organ)

From Wikipedia, the free encyclopedia
Jump to: navigation, search
Uca pugnax, like other members of the family Ocypodidae, have chelae of different size: a big left chela and a small right chela.

A chela /kˈlə/, 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.
