However, the world's 3. bird—hummingbird, weighs less than 1.8 grams. Giraffes can be 5.2 metres tall, and they are the 4. animals in the world. The cheetah runs the 5. of all animals. It can run up to 120 kilometres per hour.
On the other hand, a sloth(树懒) is perhaps the world's 6. animal. It often does not move for hours. The 7. land animal is the howler monkey(吼猴). You can hear its cry about 3 to 5 kilometres away. What is the 8. sea animal? The blue whale. Blue whales can hear each other up to 1,600 kilometres away. What is the animal that lives the 9. ? It's a clam(蛤) from the coast of Iceland. Scientists believe that it was 405 years old. The mayfly(蜉蝣), a tiny insect with wings, has the 10. life—only one day.
