Editing Claw (section)

====Primates====
[[Primate]] nails consist of the unguis alone, as the subunguis has disappeared. With the evolution of grasping hands and feet, claws are no longer necessary for locomotion, and instead most digits exhibit [[nail (anatomy)|nail]]s. However, claw-like nails are found in small-bodied [[callitrichids]] on all digits except the [[hallux]] or big toe. A laterally flattened [[grooming claw]], used for grooming, can be found on the second toe in living [[Strepsirrhini|strepsirrhines]], and the second and third in [[tarsiers]]. [[Aye-aye]]s have functional claws on all other digits except the hallux, including a grooming claw on the second toe.<ref name="Soligo">{{Cite journal | last1 = Soligo | first1 = C. | last2 = Müller | first2 = A.
