Un the zone G, live animals living in frigid areas, such as north and south poles.
1. Penguins
Penguins (Spheniscidae family, order Sphenisciformes) are a group of marine birds, flightless, distributed only in the Southern Hemisphere, especially in its high latitudes.
The first Europeans to see the birds were members of the first expedition of Vasco da Gama, who called them birds boobies child or his clumsy gait erect and being a flightless bird.
2. Ursus Marítimas
Also called white bear, is the common name given to the species of bear that lives in the Arctic ice in Hudson and James Bays, Canada, as well as on the east coast of Greenland.
It has a more elongated body and stylish as the rest of the bears due to their aquatic habits, but like the other species, its ride is plantigrade, and paws have five sharp, curved claws that they use to grip the ice and catch their prey.
Animals are well adapted to their environment; the soles of the feet are covered with long hairs that provide protection against the cold of the ice, and the front legs, besides having very wide feet, they are lined by a hard and rigid coat: use them as an oar to Best swim.
All polar bears are white, but the effect of light can aparecier brown, and even green clear.
Polar bears feed on fruits, plants, mussels and seaweed, but their favorite prey is seals, but occasionally captured walruses.
Polar bears are very hardy animals: a male can weigh up to 800 kg, while the average weight of females is 250 kg and males 350 kg.
3. Phocidae
This marine mammal pinniped group (the same group of pinnipeds belong walruses, sea lions and elephants) live in cold and temperate seas, except seal "white belly" or seal "monk" who lives in subtropical waters .
It is carnivorous, feeding on fish, squid and molluscs, live in groups and have a body torpedo-shaped, with small head, snout with long hair as a mustache, ears reduced almost to simple holes and short legs, with a membrane joining the fingers. It has a very short tail.
Their size varies by species, but do not exceed 3 meters in length and less than 1 meter 30 centimeters.
The seal is an excellent swimmer chest and back, dives and reaches depths of up to 60 meters and can stay underwater for 10 to 15 minutes.
They live in unfrequented coasts, in groups, and move over rocks in short jumps. And in winter often remain long under the ice covering the waters, but small open "vents" peer to breathe. And his worst enemy, the polar bear, may be lurking and use that opportunity to attack. Your other enemies are sharks and man. Eskimos practice in sealing a vital issue since it is a real need, as it often depend for survival: get her to eat meat, fat and achieve heat for light, baits to hunt polar bears, skins to build their tents, sleds and harnesses bones which made by hand everyday utensils.
