Wildebeest
Both species of wildebeest are even-toed, horned, greyish-brown ungulates resembling cattle. Males are larger than females and both have heavy forequarters compared to their hindquarters. They have broad muzzles, Roman noses, and shaggy manes and tails. The most striking morphological differences between the black and blue wildebeest are the orientation and curvature of their horns and the color of their coats. The blue wildebeest is the bigger of the two species. In males, blue wildebeest stand 150 cm tall at the shoulder and weigh around 250 kg, while the black wildebeest stands 111 to 120 cm tall and weighs about 180 kg. In females, blue wildebeest have a shoulder height of 135 cm and weigh 180 kg while black wildebeest females stand 108 cm at the shoulder and weigh 155 kg. The horns of blue wildebeest protrude to the side, then curve downwards before curving up back towards the skull, while the horns of the black wildebeest curve forward then downward before curving upwards at the tips. Blue wildebeest tend to be a dark grey color with stripes, but may have a bluish sheen. The black wildebeest has brown-coloured hair, with a mane that ranges in color from cream to black, and a cream-coloured tail. The blue wildebeest lives in a wide variety of habitats, including woodlands and grasslands, while the black wildebeest tends to reside exclusively in open grassland areas. In some areas, the blue wildebeest migrates over long distances in the winter, whereas the black wildebeest does not. The milk of the female black wildebeest contains a higher protein, lower fat, and lower lactose content than the milk of the blue wildebeest. Wildebeest can live more than 40 years, though their average lifespan is around 20 years.
Alaska Peninsula brown bear
Alaska Peninsula brown bears are the second largest type of brown bear in the world, only after the giant bears of Kodiak Island. They usually measure 8 feet (2.4 m) in length, usually have a shoulder height of about 4-4-1/2 feet (1.2-1.4 m), and a hindfoot length of 11 in (28 cm). One study found that the average weight for a coastal male was around 408 kilograms (900 lb). For a female, this average weight would be 227 kilograms (500 lb). On the other hand, an occasional huge male brown has been recorded which greatly exceeds ordinary size, with weights reported up to . A large coastal male of this size may stand up to tall on its hind legs and be up to at the shoulder. The biggest individual on record was shot in 1948 near Cold Bay. Its weight was estimated at to . This bear just came out of hibernation and carried little or no fat; that means the animal would have weighed around at the end of the summer. Although variable from blonde 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.
