Kangaroo : interesting facts about kangaroos

A newborn kangaroo is about 1 inch in length.
Kangaroos are the largest marsupial mammals. It is a macropod which means "big foot".
There are over 40 different types (species) of Kangaroo.
The Red Kangaroo is the largest living marsupial and can grow to two meters. It weighs up to 90 kg (200 pounds).
Kangaroos are the only large animals that move by hopping. They can't move backward.
On land kangaroos can't move their hind legs independently, only together. But when they are swimming (they are good swimmers) they kick each leg independently.

When European explorers first saw these strange hopping animals they asked a native Australian (aborigine) what they were called. He replied "kangaroo" meaning "I don't understand" your question. The explorers thought this was the animal's name. And that's how the kangaroo got its name.

Female kangaroos enter into heat within a few days after giving birth they mate and conceive, but after only one week's development the microscopic embryo enters a dormant state that lasts until the previous young leaves the pouch. All kangaroos have a chambered stomach similar to cattle and sheep. They regurgitate the vegetation they have eaten, chew it as cud, and then swallow it again for final digestion. The Red kangaroo grazes during the night on a wide variety of grasses and low herbaceous plants, though sometimes this grazing period starts late evening and ends early morning. Kangaroos mate again as soon after a joey is borne, but the development of the second embryo stops, or rather, is paused after a few days. So in a way kangaroos are permanently pregnant. If a joey is lost, or if one has grown up and left the pouch, they can immediately give birth again.

The Kangaroo moves by hopping on its powerful hind legs. It uses its thick long tail to balance its body while hopping. A kangaroo can hop at up to 60kmh (40mph). It can also leap over obstacles up to 3m (10ft) high. Because of the unusual shape of its legs and its bulky tail a kangaroo can't walk or move backwards very easily. Kangaroos are found in Australia, Tasmania, and New Guinea. The Kangaroo moves by hopping on its hind legs using its tail for steering and balancing while hopping at speed up to 40mph/60kmh. When kangaroo is moving slowly the tail is used as an extra leg and supports the kangaroo when it is standing on its hind legs. Most kangaroos can only move both back legs together and not one at a time.

A male kangaroo is called a buck or a boomer or an old man.
A female kangaroo is called a flyer
A baby kangaroo is called a joey
A group of kangaroos is called a mob.
"Roos" is a colloquial name used for any kangaroos or wallabies.
Eastern Grey Macropus giganteus 3 - 8ft (0.9 - 2.4m) 40 - 200 lbs (18 - 95kg)
