National Science Foundation The polar bear travels long distances over vast desolate expanses, generally on drifting oceanic ice floes, searching for seals, its primary prey. Many bear species primarily eat specific foods, such as seals for the polar bear or termites and fruit for the sloth bear, but with the exception of the giant panda, which exclusively eats bamboo, ursids are omnivorous when necessary. Ursinae (all living bears except giant panda and the spectacled bear), Help support the North American Bear Center. Ursids are the largest of all terrestrial carnivores. The polar bear's binomial name is Ursus maritimus, determined by the English explorer Constantine Phipps in 1774. (Yu et al 2007) (Yu et al 2004) (Schliebe et al 2006), Describer (Date): Phipps (1774:p.185) A Voyage Towards North Pole, London: J. Nourse for Ursus maritimus. In addition to being placed within the three extant subfamilies, they have been categorized within the extinct subfamilies Agriotheriinae, Amphicynodontinae, Hemicyoninae, and Ursavinae, some of which are subdivided into named tribes. "Ursus maritimus" is Latin for "sea bear."

The polar bear. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. Grizzly Bear Scientific Name The grizzly bear is a subspecies of the brown bear known as Ursus Arctos. The following classification is based on the taxonomy described by Mammal Species of the World (2005), with augmentation by generally accepted proposals made since using molecular phylogenetic analysis; this includes the division of the giant panda into two subspecies. A boar (adult male) weighs around 350–700 kg (772–1,543 lb), while a sow (adult female) is about half that size.

Most bears are 1.2–2 m (4–7 ft) long, plus a 3–20 cm (1–8 in) tail, though the polar bear is 2.2–2.44 m (7–8 ft) long, and some subspecies of brown bear can be up to 2.8 m (9 ft). A new paper written by zoologist Dr Susan Crockford to mark International Polar Bear Day today has found that global polar bear numbers have continued to rise. A member of this family is called a bear or an ursid. Large Polar Bear, Alaska.

Taxonomists currently separate black bears into the following 16 subspecies based on minor differences in appearance and DNA. Brown Bears (includes Grizzly Bears) and Polar Bears diverged from the Black and Sun Bears in the last 6.1 million years ago (Pliocene). It is the biggest species of bear in the world (with the exception of the Kodiak Brown Bears found in Alaska which can reach similar sizes) with males often weighing-in at around 600kg.
