Suina

The suborder Suina (also known as Suiformes) is a lineage of omnivorous non-ruminant artiodactyl mammals that includes the pigs and peccaries of the families Suidae and Tayassuidae and their fossil kin. The Hippopotamidae has historically been classified among the Suina for morphological reasons, but is now more often classified as the sister group of the whales, or Cetacea.
