Ungulates account for the vast majority of large herbivores currently on earth. Their influence stretches across nearly every biome, and their indigenous range includes all zoogeographic regions except Antarctica. With human help, ungulates have expanded into nearly every corner of the globe: "Ungulates of the World" indeed! The species list (below) originates from that published by Wilson and Reeder (2005), although several changes and additions have been made to reflect our current understanding of ungulate taxonomy (as per IUCN, 2010). Since species-concepts are flexible, some species recognized by other authors may not be listed here.
