Chelae is a term used to describe specialized appendages found in certain animals, such as crustaceans, arachnids, and insects. These appendages are used for grasping and manipulating objects, prey, or mates. Some synonyms for chelae include pincers, claws, mandibles, and forceps. Pincers are typically associated with animals such as crabs and lobsters, whereas claws are more commonly used to describe appendages found in scorpions and other arachnids. Mandibles refer to the jaw-like structures found in insects and some crustaceans, while forceps are usually used to describe medical or laboratory equipment used for grasping or holding objects. Despite their differing names, chelae and their synonyms serve a similar function in helping animals to interact with their environment.
