The pig-like (Suina), also called " non-ruminants " (Nonruminantia), are a subordination of the artifacts . Compared to the callous soles and ruminants, they are characterized by relatively little specialization. Your stomach has two or three chambers and is not capable of ruminating. The non-ruminants include two recent families , the Old World or real pigs (Suidae) and the New World or umbilical pigs (Tayassuidae), these are united as the superfamily Suoidea. Another extinct superfamily of large pig-like animals are the Entelodontidea with the only family Entelodontidae .
In the past, the hippos were also included in this group, but according to more recent molecular genetic studies they are not very closely related to the pig species, instead they are the closest relatives of the whales .
