Shared characteristics of odd-toed ungulates include them being herbivores and each having 1 or 3 hoofed toes on each hindfoot. They also have a long upper jaw and a reduced ulna and fibula bones simplifying both the wrist and ankle joint. They don’t have a clavicle bone making running more efficient.

The most notable difference between even and odd-toed ungulates is the number of toes they have. Odd-toed ungulates have an odd number of toes, while even-toed ungulates have an even number of toes (2 or 4). Odd-toed ungulates are able to digest plant matter in their intestines, while even-toed ungulates digest their meals in one or more stomach chambers.
