1. The smallest specimen in the bird world is the hummingbird. These tiny creatures have a high metabolism that keeps their hearts beating at the incredible rate of 1,260 times per minute. A hummingbird's heart is 2.4 percent of its body weight, which is typically three grams. Even when it is at rest, a hummingbird takes 250 breaths every minute. Though they are tiny, these birds have incredible stamina. A male ruby-throated hummingbird's wingbeats have been registered at 78 times per second when he is in ordinary flight, and these beats may increase to more than 200 during a dive.
2. Koalas are marsupials that are related to kangaroos and opossums. Marsupials are mammals that have a bag or pouch for their young. At birth, a koala is only one inch long and must find a way to reach its mother's pouch, where it will stay for seven to nine months. When the young koala is strong enough to leave the pouch, it may still stay with its mother for as long as two years. Although they are not bears, koalas are sometimes called koala bears. The name koala is an aboriginal word that means "one who does not need to drink." Koalas drink very little because they eat eucalyptus leaves, which contain a lot of water. Because of deforestation and disease, koalas are not as common as they once were.
