The four summarized Artiodactyla taxa are divided into ten extant families: [26] The camelids ( Tylopoda ) comprise only one family, Camelidae . It is a species-poor artiodactyl suborder of North American origin [ 27 ] that is well adapted to extreme habitats—the dromedary and Bactrian camels in the Old World deserts and the guanacos , llamas ...
The order Artiodactyla consists of 349 extant species belonging to 132 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 132 genera can be grouped into 23 families; these families are grouped into named suborders and many are further grouped into named clades, and some of these families are subdivided into named subfamilies.
The evolution of cetaceans is thought to have begun in the Indian subcontinent from even-toed ungulates (Artiodactyla) 50 million years ago (mya) and to have proceeded over a period of at least 15 million years. [2] Cetaceans are fully aquatic mammals belonging to the order Artiodactyla and branched off from other artiodactyls around 50 mya.

The pronghorn (UK: / ˈ p r ɒ ŋ h ɔːr n /, US: / ˈ p r ɔː ŋ-/) [4] (Antilocapra americana) is a species of artiodactyl (even-toed, hoofed) mammal indigenous to interior western and central North America.
The preorbital gland is a paired exocrine gland found in many species of artiodactyls, which is homologous to the lacrimal gland found in humans. These glands are trenchlike slits of dark blue to black, nearly bare skin extending from the medial canthus of each eye.
Ungulates are distinguished by the structure of their feet and how they walk. The hoof is made of an outer layer of keratin called unguis. Instead of horn-shaped feet, elephants have wide stump ...
Nevertheless, the structure of the mandibular condyle itself allowed for a wide range of movement, and the laterally bowed zygomatic arch provided some room for side-to-side (transverse) movement driven by the masseter and pterygoideus. The low, unconstrained jaw joint and short coronoid process may correspond to long muscle fibers.
