Claws are sharp, curved appendages found on the feet of birds and some mammals. The term 'claws' can refer to a variety of different structures, including TALONS, NIPPERS, and tearsats. TALONS are the large, curved claws found on the feet of birds of prey, such as eagles and hawks. NIPPERS are smaller, more pointed claws found on the feet of smaller birds, such as finches and sparrows. Tearsats are the long, curved claws found on the feet of cats and other felines. All of these structures are referred to as claws, and they all serve the same purpose: to help animals grip and hold onto their prey.
