A claw is a curved, pointed appendage, found at the end of a toe or finger in most amniotes . However, the word "claw" is also often used in reference to an invertebrate. Somewhat similar fine hooked structures are found in arthropods such as beetles and spiders, at the end of the leg or tarsus for gripping a surface as the creature walks. Crabs', lobsters' and scorpions' pincers, or more formally, their "chelae", are sometimes called claws.
