Polar Bear - Ursus maritimus
The polar bear (Ursus maritimus) is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is a large bear, approximately the same size as the omnivorous Kodiak bear (Ursus arctos middendorffi). Its thick blubber and fur insulate it against the cold. Its fur is hollow and translucent but usually appears as white or cream coloured, thus providing the animal with effective camouflage. Its skin is actually black in color, however. The bear has a short tail and small ears that help reduce heat loss, as well as a relatively small head and long, tapered body to streamline it for swimming. The polar bear is a semi-aquatic marine mammal that depends mainly upon the pack ice and the marine food web for survival. It has adapted for life on a combination of land, sea, and ice. Scientists and climatologists believe that the projected decreases in the polar sea ice due to global warming will have a significant negative impact on of this species within this century. The polar bear (Ursus maritimus) is the largest species of all bears and is the largest terrestrial carnivore on earth. Fully grown male polar bears range from 7' to 11' when standing upright, and weigh from 660 to 1,320 pounds. Females stand from 6' to 8' and weigh anywhere from 400 to 700 pounds. The largest polar bear on record was over 12' and weighed 2,210 pounds.

Steller's Sea Lion - Eumetopias jubatus
The Steller sea lion (Eumetopias jubatus) also known as the northern sea lion, is a threatened species of sea lion in the northern Pacific. It is the sole member of the genus Eumetopias and the largest of the eared seals (Otariidae). Among pinnipeds, it is inferior in size only to the walrus and the two elephant seals. Adult animals are lighter in color than most sea lions, ranging from pale yellow to tawny and occasionally reddish. Steller sea lion pups are born almost black, weighing around 23 kg (51 lb), and remain dark for several months. Females and males both grow rapidly until the fifth year, after which female growth slows considerably. Adult females measure 2.3–2.9 m (7.5–9.5 ft) in length, with an average of 2.5 m (8.2 ft), and weigh 240–350 kg (530–770 lb), with an average of 263 kg (580 lb). Males continue to grow until their secondary sexual traits appear in their fifth to eighth year. Males are slightly longer than the females; they grow to about 2.82–3.25 m (9.3–10.7 ft) long, with an average of 3 m (9.8 ft). Males have much wider chests, necks and general forebody structure and weigh 450–1,120 kg (990–2,500 lb), with an average of 544 kg (1,200 lb). Males are further distinguished from females by broader, higher foreheads, flatter snouts, and darker, slightly tuftier hair around their large necks, giving them a maned appearance. Indeed, their Latin name translates roughly as: "maned one with the broad forehead".
