Suina refers to a suborder of mammals that includes pigs and their wild relatives. This group is part of the order Artiodactyla, which consists of even-toed ungulates. Suina is characterized by their stout bodies, short legs, and distinctive snouts, which are adapted for rooting in the ground for food. Members of the Suina suborder are primarily omnivorous, feeding on a variety of plant materials, insects, and small animals. The domestic pig, a well-known member of this group, has been bred for various purposes, including meat production and companionship. Wild relatives, such as wild boars, play important roles in their ecosystems.
