Artiodactyls, classified in the order Artiodactyla, are even-toed ungulate mammals characterized by bearing weight primarily on the third and fourth digits of each limb, which are usually of similar size and aligned symmetrically. This order includes diverse families such as Bovidae (cattle, antelopes, goats), Cervidae (deer), Suidae (pigs), and Hippopotamidae (hippopotamuses), and, in many modern treatments, is combined with Cetacea in the clade Cetartiodactyla based on molecular and morphological evidence. Artiodactyls exhibit a wide range of digestive specializations, notably ruminant foregut fermentation in many lineages, and occupy varied terrestrial and semi-aquatic ecological niches.
