Mammals

Gorilla

Gorilla

The largest of the world's primates, it is thought that the gorilla lineage split from that of the chimpanzee and humans about seven million years ago. In spite of their fearsome appearance, gorillas are not aggressive by nature.

Gray Whale

Gray Whale

Gray whales undertake one of the longest migratory journeys of any creature on earth. Their size means that their only major predators are killer whales. In autumn they swim from Arctic waters down the western coast of North America.

Grevy's Zebra

Grevy's Zebra

Grevy's zebra has a long head, broad, rounded ears and a relatively short, strong neck. An erect mane runs from its crown down the back of its neck. Its body is white with black stripes, both narrower and more numerous than those of the common zebra.

Grey Fox

Grey Fox

These attractively coloured canids differ from other species of fox in that they are adept at climbing, rather than spending all their time on the ground. Their range continues down the western side of Central America to northern Colombia.

Grey Seal

Grey Seal

Grey seals live across the North Atlantic. As well as on the coast of Canada's maritime provinces, the grey seal is found from Iceland to the coast of northern Europe and in the Baltic Sea. A few colonies even exist as far south as northern Spain and Portugal.

Grey Wolf

Grey Wolf

This species was one of the most widely distributed mammals in the northern hemisphere, but hunting pressures and increasing urbanization have greatly reduced its range. All domestic dogs are descended from grey wolf, which began living alongside humans.

Grison

Grison

The greater grison's range stretches from S. Mexico to Brazil and Bolivia. These animals are found mainly in lowland areas, rarely ascending to more than 1,500 m (5,000 ft) above sea level. There are 3 species of grison, all of which live in C. and S. America.

Grizzly Bear

Grizzly Bear

Many subspecies are covered by the scientific name U. arctos, including the Kodiak bear and the grizzly bears. This particular race of the brown bear is characterised by its "grizzled" or greyish fur, thanks to the colouration at the tips of its hairs.

Guanaco

Guanaco

The guanaco is a slender, long-limbed animal, which is capable of fast movement over rugged terrain and is able to leap nimbly up mountain trails. It is adaptable to heat or cold and lives in open country and feeds on grass.

Hairy-tailed Mole

Hairy-tailed Mole

As its name implies, this species is characterized by its almost bushy tail. Otherwise it is similar to other moles in habits and appearance. The hairy-tailed mole ranges from southern Quebec and Ontario to central Ohio and western North Carolina.
