Suidae is a family of artiodactyl mammals which are commonly called pigs, hogs, or swine. In addition to numerous fossil species, 18 extant species are currently recognized (or 19 counting domestic pigs and wild boars separately), classified into between four and eight genera .
The pig (Sus domesticus), also called swine (pl.: swine) or hog, is an omnivorous, domesticated, even-toed, hoofed mammal. It is named the domestic pig when distinguishing it from other members of the genus Sus. It is considered a subspecies of Sus scrofa (the wild boar or Eurasian boar) by some authorities, but as a distinct species by others.
Suina (also known as Suiformes) is a suborder of omnivorous, non-ruminant artiodactyl mammals that includes the domestic pig and peccaries. A member of this clade is known as a suine. Suina includes the family Suidae, termed suids, known in English as pigs or swine, as well as the family Tayassuidae, termed tayassuids or
The pig-like creatures are made up of two families: The pigs are limited to the Old World. These include the wild boar and the domesticated form, the domestic pig. The peccaries (Tayassuidae) are named after glands on their belly and are indigenous to Central and South America. The ruminants consist of six families:
The wild boar (Sus scrofa), also known as the wild swine, [4] common wild pig, [5] Eurasian wild pig, [6] or simply wild pig, [7] is a suid native to much of Eurasia and North Africa, and has been introduced to the Americas and Oceania. The species is now one of the widest-ranging mammals in the world, as well as the most widespread suiform. [5]
The first artiodactyls looked like today's chevrotains or pigs: small, short-legged creatures that ate leaves and the soft parts of plants. By the Late Eocene (46 million years ago), the three modern suborders had already developed: Suina (the pig group); Tylopoda (the camel group); and Ruminantia (the goat and cattle group). Nevertheless ...
Romans sacrificed pigs to their gods and created an elaborate pork-based cuisine, including some dishes — such as roast udder of lactating sow — that could make even a gentile shudder.
Most ruminants do not have upper incisors; instead, they have a thick dental pad to thoroughly chew plant-based food. [28] Another feature of ruminants is the large ruminal storage capacity that gives them the ability to consume feed rapidly and complete the chewing process later.
