Artiodactyla of the world

The even-toed ungulates (Artiodactyla /ˌɑːrtioʊˈdæktɪlə/, from Ancient Greek ἄρτιος, ártios 'even', and δάκτυλος, dáktylos 'finger, toe') are ungulates—hoofed animals—which bear weight equally on two (an even number) of their five toes: the third and fourth. The other three toes are either present, absent, vestigial, or pointing posteriorly. By contrast, odd-toed ungulates bear weight on an odd number of the five toes. Another difference between the two with the exception of Suina many other even-toed ungulates digest plant cellulose in one or more stomach chambers rather than in their intestine as the odd-toed ungulates do.
