Wallaby

Wallaby — A wallaby is any of about thirty species of macropod (Family Macropodidae). It is an informal designation generally used for any macropod that is smaller than a kangaroo or wallaroo that has not been given some other name.

Very small forest-dwelling wallabies are known as pademelons (genus Thylogale) and dorcopsises (genera Dorcopsis and Dorcopsulus). The name wallaby comes from the Eora Aboriginal tribe who were the original inhabitants of the Sydney area. Young wallabies are known as “joeys”, like many other marsupials.

Wallabies are widely distributed across Australia, particularly in more remote, heavily timbered, or rugged areas, less so on the great semi-arid plains that are better suited to the larger, leaner, and more fleet-footed kangaroos. They are widespread in New Zealand, where they are often hunted. There are also a few populations of wallabies in the British Isles all having escaped from zoos, the largest of which can be found on the Isle of Man where there are around 80 wallabies and are breeding.

Wallabies are not a distinct biological group. Nevertheless they fall into several broad categories. Typical wallabies of the Macropus genus, like the Agile Wallaby (Macropus agilis), and the Red-necked Wallaby (Macropus rufogriseus) are most closely related to the kangaroos and wallaroos and, size aside, look very similar. These are the ones most frequently seen, particularly in the southern states.

Rock-wallabies (genus Petrogale), rather like the goats of the northern hemisphere, specialise in rugged terrain and have modified feet designed to grip rock with skin friction rather than dig into soil with large claws. There are at least fifteen species and the relationship between several of them is poorly understood. Several are endangered. Captive rock wallaby breeding programs like the one at Healesville Sanctuary have had some success and a small number have recently been released into the wild.
