This enables them to extend their stride length and so move faster. Phyla Porifera (sponges) Ctenophora (comb jellies) Cnidaria (coral, jellyfish, anemones) Placozoa (trichoplax) Subregnum Bilateria (bilateral symmetry) Acoelomorpha (basal) Orthonectida (parasitic to flatworms, echinoderms, etc. ...

The Tapiridae - the closest family to the ancestral perissodactyl condition - possess four toes on the forefeet (digit V is used on wet or marshy ground) and three on the hind.
Perissodactyls are truly unguligrade, with the heel, sole, and digits of the foot never touching the ground.
The ulna and fibula (bones in the forearm and lower leg) are reduced, simplifying the wrist/ankle joint considerably.
