Grizzly Bear - Ursus arctos horribilis
The grizzly bear (Ursus arctos horribilis), also known as the silvertip bear, the grizzly, or the North American brown bear, is a subspecies of brown bear (Ursus arctos) that generally lives in the uplands of western North America. This subspecies is thought to descend from Ussuri brown bears which crossed to Alaska from eastern Russia 100,000 years ago, though they did not move south until 13,000 years ago. Except for cubs and females, grizzlies are normally solitary, active animals, but in coastal areas, the grizzly congregates alongside streams, lakes, rivers, and ponds during the salmon spawn. Every other year, females (sows) produce one to four young (commonly two) which are small and weigh only about 500 grams (1 lb). A sow is protective of her offspring and will attack if she thinks she or her cubs are threatened. The word "grizzly" in its name refers to "grizzled" or grey hairs in its fur, but when naturalist George Ord formally named the bear in 1815, he misunderstood the word as "grisly", to produce its biological Latin specific or subspecific name "horribilis". Most adult female grizzlies weigh 130–200 kilograms (290–440 lb), while adult males weigh 180–360 kilograms (400–790 lb), averaging 134 kg (295 lb) and 220 kg (485 lb), respectfully. The average total length in this subspecies is 198 centimetres (6.50 ft), with an average shoulder height of 102 centimetres (3.35 ft) and hindfoot length of 28 centimetres (11 in). Newborn bears may weigh less than 500 grams (1 lb). In the Yukon River area, mature female grizzlies can weigh as little as 100 kilograms (220 lb). On the other hand, an occasional huge male grizzly has been recorded which greatly exceeds ordinary size, with weights reported up to 680 kilograms (1,500 lb). Although variable from blond to nearly black, grizzly bear fur is typically brown in color with white tips. A pronounced hump appears on their shoulders; the hump is a good way to distinguish a black bear from a grizzly bear, as black bears do not have this hump.
Spotted Hyenas (clan of 4) - Crocuta crocuta
Shoulder height: 70-91 cm (28-36 in)
Body length: 95-166 cm (38-65 in)
Weight: 40.5-81.7 kg (89-180 lb)
General information: The spotted hyena is a species of hyena native to Sub-Saharan Africa. It is the largest member of the Hyaenidae, and is the most social of the Carnivora in that it has the largest group sizes and most complex social behaviours. Its social organisation is unlike that of any other Carnivore, bearing closer resemblance to that of cercopithecine primates (baboons and macaques) with respect to group-size, hierarchical structure, and frequency of social interaction among both kin and unrelated group-mates. Spotted hyena society is matriarchal; females are larger than males, and dominate them. The spotted hyena is a highly successful animal, being the most common large carnivore in Africa. Its success is due in part to its adaptability and opportunism; it is both an efficient hunter and a scavenger, with the capacity to eat and digest skin, bone and other animal waste.
