Grey Wolf (pack of 5) - Canis lupus
The Grey Wolf (Canis lupus) is the largest wild canid, males averaging between 70 and 110 pounds depending on subspecies. The Wolf has a specialized body that has made it one of the world's most efficient hunters. Its powerful neck is a very important adaptation: it has to be strong to support the wolf's large head and is crucial for bringing down prey. The skull is 31cm (12 inches) long and is armed with an impressive array of large canines and carnassial teeth which, when coupled with huge jaw muscles that are evident from the large sagittal crest and wide zygomatic arches, give it an incredible biteforce that is strong enough to break the bones of prey and even crack the femur of moose. Wolves primarily feed on medium to large sized ungulates (up to the size of bison 10–15 times larger than themselves), though they are not fussy eaters. Medium and small sized animals that may supplement the diet of wolves include marmots, beaver, hares, badgers, foxes, weasels, ground squirrels, mice, hamsters, voles and other rodents, as well as insectivores.
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.
