A kangaroo is a species of herbivorous leaping marsupials found across Australia and New Guinea.
They are all members of the family Macropodidae. There are three distinctly named groups of leaping
marsupials found across Australia; these are, the Kangaroo, the largest of the species, the wallaby, the
smallest and the wallaroo the middle size species. Another group, the tree-kangaroo, which inhabits
New Guinea but is also found in a small area of north-eastern Queensland, is similar in size to the walla-
roo. Even smaller marsupials are found in iso-
lated areas across Australia, like the musky rat
-kangaroo and allied rock-wallaby. Overall,
there is around 65 species of leaping marsupi-
als. The term kangaroo is commonly used
when referring to the larger of the species, of
which, there are four, the red kangaroo, an-
tilopine kangaroo, western & eastern grey
kangaroo.
Kangaroos have a powerful muscular
body, short forelimbs with small hands bran-
dishing five long clawed fingers, large powerful
hind legs and long narrow feet with four toes.
Their head is relatively small with a short
pointed snout, round front pointing eyes and a
pair of large pointed ears. They have a long ex-

Doria's tree-kangaroo, resting during the day and foraging in the twilight hours. Although some are
Goodfellow's tree-kangaroo, solitary, others are very sociable often gathering together in groups (a Mob)
of 50 or more. However, when danger threatens, announced by one thrash-
Lowlands tree-kangaroo, ing its tail on the ground, the group disintegrates as each animal takes off at
Golden-mantled tree- speed in all different directions. They are very fast in their escape, a male (a
kangaroo, Boomer), can leap to a length of 9.1 metres, a height of 3 metres, and a
Seri's tree-kangaroo, speed of around 60km/h, while the smaller female (a Jill) is slower. Large
