The family otherwise known as the elephant family. Unlike the term "elephant" which is most commonly used to refer to only extant members of this family, "elephantid" is used to refer to any member of the elephantid family, including prehistoric members like the mammoth and stegotetrabelodon. It does not refer to other non-elephantid-family proboscidean members (e.g. mastodon, gomphotherium), however, so that term (and tag) should be used instead. These animals are mostly known for their hulking size, tough skin, tusks, and trunk. Only two genera of this family are extant -- Loxodonta (African elephants) and Elephas (Asian elephants). The remaining members are extinct. A summary of their taxonomy is listed below.
