AI overview
A claw is a curved, pointed structure found at the end of the toes or fingers of most mammals, reptiles, and birds, and similar hook-like structures exist on the legs of some invertebrates like beetles and spiders. Claws matter because they serve practical functions such as helping animals grip surfaces as they move and interact with their environment.

A claw is a curved, pointed appendage found at the end of a toe or finger in most amniotes (mammals, reptiles, birds). Some invertebrates such as beetles and spiders have somewhat similar fine, hooked structures at the end of the leg or tarsus for gripping a surface as they walk. The pincers of crabs, lobsters and scorpions, more formally known as their chelae, are sometimes called claws.
A true claw is made of a hard protein called keratin. Claws are used to catch and hold prey in carnivorous mammals such as cats and dogs, but may also be used for such purposes as digging, climbing trees, self-defense and grooming, in those and other species.
