The Sea Otter (Enhydra lutris) is a large otter native to the North Pacific, from northern Japan and Kamchatka west across the Aleutian Islands south to California. The heaviest of the otters, Sea Otters are the only species within the genus Enhydra. |
Hunted extensively for their luxurious fur—the densest of all mammals with up to 100,000 hairs per square centimeter— from 1741 onwards, sea otter populations were greatly reduced to the point of extermination in many parts of their historic range.

Python is the common name for the Boidae Family of non venomous constricting snakes—specifically the subfamily Pythonidae. |
Generally pythons range in size from less than 5m to 6m meters (15 to 20 feet) in length. They are among the longest species of snake in the world; the Reticulated Python can reach lengths of up to 10 meters (35 feet) and is the longest.

Elephants have tusks, large teeth emerging from their upper jaws. The longest elephant tusks were recorded to be 3.5 meters long. Elephant tusks are the major source of ivory, but because of the increased rarity of elephants, |
hunting and ivory trade is now restricted, and in some countries illegal.
Elephants have three premolars and three molars in each quadrant.

A kangaroo is any of several large macropods (the marsupial family that also includes the wallabies, tree kangaroos, wallaroos, pademelons and the quokka: 45 species in all). |
The term kangaroo is sometimes used in a broader sense to refer to all members of the macropod family. Kangaroos are native to the continent of Australia, while a number of tree kangaroos are found in New Guinea.

Polar bears also known as white bear or northern bear, is a large bear native to the Arctic. It is the largest land carnivore species. It is the apex predator within its range. It is well-adapted to its habitat.
|
: its thick blubber and fur insulate it against the cold, its white color camouflages it from its prey, and it hunts well both on land and in the water.

The peregrine falcon or, in North America, Duck Hawk (Falco peregrinus) is a medium-sized falcon about the size of a large crow: 38-53 cm (15 to 21 inches) long. It has a wingspan of about 1 meter (40 inches).
|
Males weigh 570-710 grams; the noticeably larger females weigh 910-1190 grams.

The Emperor penguin (Aptenodytes forsteri) is the largest of all penguins. It is the only penguin that breeds during the winter in Antarctica. Emperor Penguins eat mainly crustaceans (such as krill) but also indulge in consuming small fish and squid.
|
In the wild, Emperor Penguins typically live for 20 years, but some records indicate a maximum life span of around 40 years.

Coyotes are a member of the Canidae (the dog family) and a relative of the domestic dog. Coyotes are only found in North America. Coyotes may occasionally assemble in small packs, but
|
normally hunt alone. Coyotes live an average of about 6 years. The word "coyote" derives from the Náhuatl (Aztec) word cóyotl.

A glacier is a large, long-lasting river of ice that is formed on land and moves in response to gravity. A glacier is formed by multi-year ice accretion in sloping terrain. Glacier ice is the largest reservoir of fresh water on Earth, and second only to the oceans as the largest reservoir of total water. Glaciers can be found on every continent except Australia.
Geologic features associated with glaciers include end, lateral, ground and medial moraines that form from glacially transported rocks and debris; U-shaped valleys and cirques (cwms) at their heads, and the glacier fringe, which is the area where the glacier has recently melted.
There are two main types of glaciers: alpine glaciers, which are found in mountain terrains, and continental glaciers, which are associated with ice ages and can cover large areas of continents. Most of the concepts in this article apply equally to alpine glaciers and continental glaciers.
A temperate glacier is one where liquid water is present at least part of the year. Polar glaciers are always below the freezing point.
