Ursidae is a family of mammals in the order Carnivora, which includes the giant panda, brown bear, and polar bear, and many other extant or extinct mammals. A member of this family is called a bear or an ursid. They are widespread across the Americas and Eurasia.

Although Ursidae is not diverse, species in this family are widespread and culturally significant to human populations throughout their range. ( Flynn, et al., 2005 ; Nowak, 1991 ; Vaughan, et al., 2000 )

Jun 27, 2018 · Ursidae (bears; suborder Fissipedia (or Caniformia), superfamily Canoidea) A family of large, slow-moving mammals whose ancestors were the last group of canoids to diverge from the ancestral ‘dog’ line, some time during the Miocene and probably soon after that line became established.

Ursidae. The bears comprise another small carnivore family from which only three species of Eimeria have been described, two from black bears (Ursus americanus) in North America and one from the brown bear (U. arctos) in Russia.

The family Ursidae comprises 8 species of bears in five genera: brown bears, polar bears, American black bears, Asian black bears, sun bears, sloth bears, spectacled bears and the Giant Panda. Members of this family are distributed from the Arctic coasts to tropical jungles.

Bears have big heads, round ears, small eyes that face forward, very short tails, and stocky legs. They are plantigrade, walking on the heels and soles of their feet like humans do. Each paw has five curved claws that are not retractable, or cannot be pulled back.

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.

Ursidae is a small family of large carnivores that are found worldwide, except for in Antarctica and Australia. Just eight species in five Genera belong to the family Ursidae, including some of the largest land carnivores on the planet.

Aug 27, 2016 · Bears are mammals within the order Carnivora of the divergent family Ursidae and are geographically widespread within North and South Americas, Europe, and Asia. Within Ursidae, eight species of bears exist in three different subfamilies: Ursinae, Tremarctinae, Ailuropodinae (Table 50-1).

Thenius (1979) placed Ailuropoda in the monotypic family Ailuropodidae. Morphological studies have supported the monophyly of three subfamilies (Hendey, 1980; Kurtén, 1966; Thenius, …
