While the polar bear is mostly carnivorous, and the giant panda feeds almost entirely on bamboo, the remaining six species are omnivorous with varied diets. minimus'': the black bears (including the sun bear, the Asian black bear, and the American black bear); and the brown bears (which includes the polar bear).
The polar bear (Ursus maritimus) is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses.

While the polar bear is mostly carnivorous, and the giant panda feeds almost entirely on bamboo, the remaining six species are omnivorous with varied diets. Modern bears comprise eight species in three subfamilies: Ailuropodinae (monotypic with the giant panda), Tremarctinae (monotypic with the spectacled bear), and Ursinae (containing six species divided into one to three genera, depending on the authority).
The giant panda (Ailuropoda melanoleuca; ), also known as panda bear or simply panda, is a bear native to south central China.

Carnivora

Bears are carnivoran mammals of the family Ursidae.
Others, such as raccoons and bears, are more omnivorous, depending on the habitat.

Bear-baiting

bear baitingbearbear-
Bears have been hunted since prehistoric times for their meat and fur; they have been used for bear-baiting and other forms of entertainment, such as being made to dance.
Bear-baiting is a blood sport involving the worrying or tormenting (baiting) of bears.

Bile bear

In modern times, bears have come under pressure through encroachment on their habitats and illegal trade in bear parts, including the Asian bile bear market.
Bile bears, sometimes called battery bears, are bears kept in captivity to harvest their bile, a digestive fluid produced by the liver and stored in the gallbladder, which is used by some traditional Chinese medicine practitioners.

Brown bear

Ursus arctosbearbrown
The IUCN lists six bear species as vulnerable or endangered, and even least concern species, such as the brown bear, are at risk of extirpation in certain countries.
The brown bear (Ursus arctos) is a bear species that is found across much of northern Eurasia and North America.

Mammal

Bears are carnivoran mammals of the family Ursidae.
The next three biggest orders, depending on the biological classification scheme used, are the Primates including the apes, monkeys and lemurs; the Cetartiodactyla including whales and even-toed ungulates; and the Carnivora which includes cats, dogs, weasels, bears, seals and allies.

Hibernation

Bears use shelters, such as caves and logs, as their dens; most species occupy their dens during the winter for a long period of hibernation, up to 100 days.
Although traditionally reserved for "deep" hibernators such as rodents, the term has been redefined to include animals such as bears and is now applied based on active metabolic suppression rather than any absolute decline in body temperature.

Carnivore

While the polar bear is mostly carnivorous, and the giant panda feeds almost entirely on bamboo, the remaining six species are omnivorous with varied diets.
For example, while the Arctic polar bear eats meat almost exclusively (more than 90% of its diet is meat), most species of bears are actually omnivorous, and the giant panda is exclusively herbivorous.

Arctic

Arctic regionThe Arcticcircumpolar
Bear taxon names such as Arctoidea and Helarctos come from the ancient Greek word ἄρκτος (arktos), meaning bear, as do the names "arctic" and "antarctic", from the constellation Ursa Major, the "Great Bear", prominent in the northern sky.
The word Arctic comes from the Greek word (arktikos), "near the Bear, northern" and that from the word (arktos), meaning bear.

Ailuropodinae

Ailuropodinae is a subfamily of Ursidae that contains only one extant species, the giant panda (Ailuropoda melanoleuca) of China.

Ursinae

Modern bears comprise eight species in three subfamilies: Ailuropodinae (monotypic with the giant panda), Tremarctinae (monotypic with the spectacled bear), and Ursinae (containing six species divided into one to three genera, depending on the authority).
Ursinae is a subfamily of Ursidae (bears) named by Swainson (1835) though probably named before Hunt 1998.

Ursid hybrid

polar bears and brown bears
Nuclear chromosome analysis show that the karyotype of the six ursine bears is nearly identical, with each having 74 chromosomes (see Ursid hybrid), whereas the giant panda has 42 chromosomes and the spectacled bear 52.
An ursid hybrid is an animal with parents from two different species or subspecies of the bear family (Ursidae).

Hemicyoninae

hemicyonineHemicyonidae
The raccoon-sized, dog-like Cephalogale is the oldest-known member of the subfamily Hemicyoninae, which first appeared during the middle Oligocene in Eurasia about 30 Mya.
Hemicyoninae is an extinct subfamily of Ursidae often called "dog-bears", literally "half dog" (Greek: ἡμικυων "hemi-kyōn"), bear-like carnivoran living in Europe, North America, Africa and Asia during the Oligocene through Miocene epochs 33.9–5.3 Ma, existing for approximately.

Parictis

Parictis parvas, P. Nimravid
The earliest members of Ursidae belong to the extinct subfamily Amphicynodontinae, including Parictis (late Eocene to early middle Miocene, 38–18 Mya) and the slightly younger Allocyon (early Oligocene, 34–30 Mya), both from North America.
Parictis is the earliest genus of bears known.

By 3–4 Mya, the species Ursus minimus appears in the fossil record of Europe; apart from its size, it was nearly identical to today's Asian black bear.

Sloth bear
