Camels have a long track that splays a lot to help with traction in the sand. And the soft pad takes up most of the space in the foot, which gives the bottom of the track a wavy appearance (instead of being a flat footprint). The hard toenails are just a little of the track at the front.
Compared to cattle, which have a hard toenail that runs down almost the entire track, they rarely splay very much, and the bottom of the track is totally flat.
Hope that helps. preston
