[AS.] The toe nail of a beast or bird. The claw of the lion may be unsheathed or put out, and withdrawn or sheathed. The claws of the dog, which catches its prey with its teeth, are blunt, and cannot be withdrawn. The hawk and the eagle, that seize their prey alive, have all their toes or claws long, curved, strong, and sharp; but the vultures, that feed on dead animals, have short hind toes, nearly flat front ones, and all very weak. The bustard has no hind toe. Each foot of the spider has three claws : the middle one is bent over for clinging to the web; the other two have teeth like a comb, and are used sometimes for cleansing the limbs and webs.
