Kangaroos
Ever since they were discovered by early settlers, kangaroos have fascinated biologists. They are unique animals, considered both comical and exotic. They are found only in Australia, New Zealand and a few surrounding islands. There are more than fifty species of kangaroos in existence today. The best known and largest species is the red and gray kangaroos, which can stand up to six feet and can weigh nearly 200 pounds. They have large ears, and relatively small heads. Their front limbs are very small, but their paws are very nimble. Their hind legs are very large and powerful. When they are moving slowly, kangaroos walk on all four limbs, with the front limbs barely touching the ground. But when they feel the need to move quickly, they stand nearly upright, and start hopping on their hind legs. When they begin to hop, kangaroos use their muscular, agile tails to balance themselves, and to help them change direction. Like all marsupials, kangaroos carry their offspring in a pouch. Kangaroos are herbivores, subsisting upon grass and other forest vegetation. Like many other grazing animals, kangaroos have developed multi-chambered stomachs to aid in the breakdown of otherwise indigestible plant material.
