Various carnivorans, with feliforms to the left, and caniforms to the right. Carnivora is an order of placental mammals that have specialized in primarily eating flesh. Members of this order are called carnivorans, or colloquially carnivores, though the term more properly refers to any meat-eating organisms, and some carnivoran species are omnivores or herbivores.
It is the largest extant bear species, as well as the largest extant land carnivore. A boar (adult male) weighs around 350–700 kg (770–1,540 lb), while a sow (adult female) is about half that size.
Polar bear feeding on a seal on an ice floe north of Svalbard, Norway. It is the most carnivorous species. The sloth bear is not as specialized as polar bears and the panda, has lost several front teeth usually seen in bears, and developed a long, suctioning tongue to feed on the ants, termites, and other burrowing insects
The Kodiak bear, a brown bear (U. arctos) subspecies, rivals the polar bear in size, but is slightly smaller. It has a similar body length with the largest confirmed wild specimen weighing 751 kg (1,656 lb). The largest bear, and possibly the largest known mammalian land carnivore of all time, was Arctotherium angustidens.
The order Carnivora is the sixth largest order of mammals, [22] comprising at least 279 species on every major landmass and in a variety of habitats, ranging from the cold polar regions of Earth to the hyper-arid region of the Sahara Desert and the open seas. Carnivorans exhibit a wide array of body plans, varying greatly in size and shape.
The polar bear is the most carnivorous of bears due to the arctic climate in which it lives, and shows a preference for eating seals. The giant panda is the most herbivorous bear and has evolved a number of adaptations, including a sixth "toe", specialized teeth, and strong jaw muscles, to allow it to feed nearly exclusively on bamboo , a tough ...
