bovid
American bison, or plains buffalo (Bison bison).
Bovids are classified within the order Artiodactyla primarily because they are even-toed ungulates, meaning they possess an even number of toes on each foot.12
Specifically, the following hoof and limb features define their placement in this order:
- Paraxonic Support: In all artiodactyls, the main weight-bearing axis of the leg passes between the third and fourth toes.3
- Toe Development: Evolution has favored the development of the third and fourth toes, while the second and fifth toes have undergone a parallel decline.3
- Cloven Hooves: Because each of these two main toes is covered by a separate hoof, the feet appear split or "cloven," a characteristic feature of many two-toed artiodactyls.2
These adaptations allow bovids to effectively bear their body weight on the tips of their toes, facilitating the speed and endurance necessary for their survival.2
