This type of mammal specialize in eating ants and termites, but recent scientific work has shown that, although aardvarks and pangolins share some superficial resemblance and behaviour, they do not have common ancestry.
The 9 species of gibbons are found in Southeast Asia, Sumatra, Java and Borneo. Like the apes, gibbons lack an external tail and have a protruding jaw. The gibbons are agile, slender primates weighing between 11 and 28 lb (5 and 13 kg).
The giraffe family is a specialized offshoot of the deer family. It probably originated in the Old World and is now reduced to only 2 species, both found in Africa. Both animals have unique, skin-covered, blunt horns, which are not shed.
One of the most colourful of all monkeys, the golden lion tamarin has suffered from the extensive deforestation of its forest habitat, and is now considered endangered. The wild golden lion tamarin population had fallen to about 100 by the early 1980s.
Golden moles are found only in Africa, south of a line linking Cameroon with Tanzania. They occur in all habitats from rugged mountainous zones to sandy plains. Their niche is filled by another group of insectivores called the golden moles.
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 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 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.
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 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.
