Definition
The distal (third) phalanx differs between species to conform to the hoof or to the claw that encloses it. They have in common an articular facet, a parietal surface and a solar surface.
In carnivores, the distal phalanx shows a hook-like appearance and is laterally compressed and drawn out to a sharp point, which is covered by the horny claw.
