Scientific classification Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Artiodactyla Family: Bovidae Genus: Bison Species: B. bonasus Binomial name Bison bonasus (Linnaeus, 1758) The wisent, or European bison (Bison bonasus), is a bison species and the heaviest surviving land animal in Europe. A typical wisent is about 2.9–3.0 m (9.5 ft) long and 1.8–2.2 m (5.9–7.4 ft) tall, and weighs 300–920 kg (660–2000 lb). It is typically smaller than the related American bison (Bison bison), and has shorter hair on the neck, head, and forequarters, but longer tail and horns. Wisent are now forest-dwelling. They have few predators (besides humans) with only scattered reports from the 1800s of wolf and bear predation. Wisent were first scientifically described by Carolus Linnaeus in 1758. Some later descriptions treat the wisent as conspecific with the American bison. It is not to be confused with the aurochs, the extinct ancestor of domestic cattle. In 1996 the IUCN classified the wisent as an endangered species. In the past it was commonly killed to produce hides and drinking horns, especially during the Middle Ages.
