What is Considered a Claw?
A claw is a narrow, arched structure that curves downward from the end of a digit in birds, reptiles, many mammals, and some amphibians, made of a hard protein called keratin, which is a modification of the epidermis. The definition of a claw is often extended to include the pincers of crabs, lobsters, and scorpions, but a true claw is specifically made of keratin and is used for various purposes such as scratching, clutching, digging, or climbing.
