Most reptiles have well-developed claws. Most lizards have toes ending in stout claws.<ref>{{cite journal|author=Alibardi, L. |year=2008|title= Microscopic analysis of lizard claw morphogenesis and hypothesis on its evolution|journal=[[Acta Zoologica]]|doi=10.1111/j.1463-6395.2007.00312.x|volume=89|issue=2|pages=169–178}}</ref> In snakes, feet and claws are absent, but in many [[boidae|boids]] such as ''[[Boa constrictor]]'', remnants of highly reduced hind-limbs emerge with a single claw as "spurs" on each side of the anal opening.

Lizard claws are used as aids in climbing, and in holding down prey in carnivorous species.
