Animal Facts
1 Bees and ants work very hard. In fact, they work harder than most animals. They never sleep but sometimes they rest for a short time.
2 Cheetahs run faster than any other animal. They can run 76 km an hour or even faster. They also sleep a lot. Sometimes they sleep 16 hours a day.
3 Whales live the longest. Elephants can live for 70 years. Turtles and people can live longer -- sometimes more than 100 years -- but whales can live for more than 200 years!
