Ursidae
Bears are carnivoran mammals of the family Ursidae. They are classified as caniforms, or doglike carnivorans. Although only eight species of bears are extant, they are widespread, appearing in a wide variety of habitats throughout the Northern Hemisphere and partially in the Southern Hemisphere. Bears are found on the continents of North America, South America, Europe, and Asia. Common characteristics of modern bears include large bodies with stocky legs, long snouts, small rounded ears, shaggy hair, plantigrade paws with five nonretractile claws, and short tails. 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. With the exception of courting individuals and mothers with their young, bears are typically solitary animals. They may be diurnal or nocturnal and have an excellent sense of smell. Despite their heavy build and awkward gait, they are adept runners, climbers, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tremarctinae
The Tremarctinae or short-faced bears is a subfamily of Ursidae that contains one living representative, the spectacled bear (''Tremarctos ornatus'') of South America, and several extinct species from four genera: the Tremarctos floridanus, Florida spectacled bear (''Tremarctos floridanus''), the North American giant short-faced bears ''Arctodus'' (''A. pristinus'' and ''A. simus''), the South American giant short-faced bear ''Arctotherium'' (including ''A. angustidens'', ''A. vetustum'', ''A. bonariense'', ''A. wingei'', and ''A. tarijense)'' as well as ''Plionarctos'' ''(P. edensis and P. harroldorum),'' which is thought to be ancestral to the other three genera. Of these, the giant short-faced bears (''Arctodus, Arctodus simus'' and ''Arctotherium, Arctotherium angustidens'') may have been the largest ever Carnivora, carnivorans in the Americas. The group is thought to have originated in eastern North America, and then invaded South America as part of the Great American Intercha ...

Ailuropodinae
Ailuropodinae is a subfamily of Ursidae that contains only one extant species, the giant panda (''Ailuropoda melanoleuca'') of China. The fossil record of this group has shown that various species of pandas were more widespread across the Holarctic, with species found in places such as Europe, much of Asia and even North America. The earliest pandas were not unlike other modern bear species in that they had an omnivorous diet but by around 2.4 million years ago, pandas have evolved to be more herbivorous. Systematics Ever since the giant panda was first described to science, they have been a source of taxonomic confusion, having been variously classified as a member of Procyonidae, Ursidae, Ailuridae, or even their own family Ailuropodidae. Part of their similarities with the red panda is in particular the presence of a "thumb" and five fingers; the "thumb" – actually a modified sesamoid bone – that helps it to hold bamboo while eating. Recent genetic studies have shown t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Bear
The brown bear (''Ursus arctos'') is a large bear species found across Eurasia and North America. In North America, the populations of brown bears are called grizzly bears, while the subspecies that inhabits the Kodiak Islands of Alaska is known as the Kodiak bear. It is one of the largest living terrestrial members of the Order (biology), order Carnivora, rivaled in size only by its closest relative, the polar bear (''Ursus maritimus''), which is much less variable in size and slightly bigger on average. The brown bear's range includes parts of Russia, Central Asia, the Himalayas, China, Canada, the United States, Hokkaido, Scandinavia, Finland, the Balkans, the Picos de Europa and the Carpathian region (especially Romania), Iran, Anatolia, and the Caucasus. The brown bear is recognized as a national and state animal in several European countries. While the brown bear's range has shrunk, and it has faced local extinctions across its wide range, it remains listed as a least con ...

Caniforms
Caniformia is a suborder within the order Carnivora consisting of "dog-like" carnivorans. They include dogs (wolves, foxes, etc.), bears, raccoons, and mustelids. The Pinnipedia (seals, walruses and sea lions) are also assigned to this group. The center of diversification for the Caniformia is North America and northern Eurasia. Caniformia stands in contrast to the other suborder of Carnivora, the Feliformia ("cat-like" carnivorans), the center of diversification of which was in Africa and southern Asia. Description Most members of this group have nonretractile claws (the fisher, marten, sea otter ( forepaws only), red panda, and ringtail, and some foxes have retractile or semi-retractile claws) and tend to be plantigrade (with the exception of the Canidae). Other traits that separate the Caniformia from the Feliformia is that caniforms have longer jaws and more teeth, with less specialized carnassial teeth. They also tend more towards omnivory and opportunistic feeding, while th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carnivora
Carnivora is a Clade, monophyletic order of Placentalia, placental mammals consisting of the most recent common ancestor of all felidae, cat-like and canidae, dog-like animals, and all descendants of that ancestor. Members of this group are formally referred to as carnivorans, and have evolved to specialize in eating flesh. The order is the fifth largest order of mammals, comprising at least 279 species. Carnivorans live on every major landmass and in a variety of habitats, ranging from the cold polar regions to the hyper-arid region of the Sahara Desert to the open seas. They come in a very large array of different body plans in contrasting shapes and sizes. Carnivora can be divided into two subclades: the cat-like Feliformia and the dog-like Caniformia, which are differentiated based on the structure of their ear bones and cranial features. The feliforms include families such as the felidae, cats, the hyenas, the mongooses and the viverridae, civets. The majority of felifor ...

Giant Panda
The giant panda (''Ailuropoda melanoleuca''), also known as the panda bear (or simply the panda), is a bear species endemic to China. It is characterised by its bold black-and-white coat and rotund body. The name "giant panda" is sometimes used to distinguish it from the red panda, a neighboring musteloid. Though it belongs to the order Carnivora, the giant panda is a folivore, with bamboo shoots and leaves making up more than 99% of its diet. Giant pandas in the wild occasionally eat other grasses, wild tubers, or even meat in the form of birds, rodents, or carrion. In captivity, they may receive honey, eggs, fish, yams, shrub leaves, oranges, or bananas along with specially prepared food. The giant panda lives in a few mountain ranges in central China, mainly in Sichuan, and also in neighbouring Shaanxi and Gansu. As a result of farming, deforestation, and other development, the giant panda has been driven out of the lowland areas where it once lived, and it is a conser ...

Hemicyoninae
Hemicyoninae is an extinct subfamily of Ursidae, often called dog bears (literally "half dog" (Ancient Greek, Greek: )). They were bear-like carnivorans living in Europe, North America, Africa and Asia during the Oligocene through Miocene epochs 33.9–5.3 Annum, Ma, existing for approximately . They are sometimes classified as a separate family (biology), family.McKenna, Malcolm C., and Bell, Susan K. 1997. ''Classification of Mammals Above the Species Level.''

Agriotheriinae
''Agriotherium'' is an extinct genus of bears whose fossils are found in Miocene through Pleistocene-aged strata of North America, Europe, Africa, and Asia. This long-lived genus persisted from at least ~11.6–2.5 Mya. Materials from the late-surviving ''A. africanum'' in Africa have suggested that ''A. africanum'' died out during the early Gelasian. Description and diet ''A. africanum'' measured around in body length and weighed up to , making it larger than most living bears; however, mass estimates vary, with further studies presenting a lower mass estimate of . Along with other large bears such as the cave bear, short-faced bears ''Arctodus'' and ''Arctotherium'', and an extinct subspecies of the modern polar bear ''Ursus maritimus tyrannus'', ''Agriotherium'' was among the largest known terrestrial members of Carnivora. They had longer legs and shorter faces than other bears, and were more lightly built. Their wide, short jaws could generate enormous bite force. It is not ...
