Animals Need Sleep Too!

People need sleep. Do birds sleep? Yes. Do giraffes sleep? Yes. All animals need sleep. Animals need different amounts of sleep. Giraffes sleep only 3 hours at night. Lions sleep 15 hours!

Lions take many short naps. They sleep during the day and also at night. They might need to wake up fast to hunt.

Whales sleep too. They have to float while they sleep. They have to breathe air too. Part of a whale’s brain tells its body to float and breathe even when it is asleep.

Little brown bats sleep the most. They sleep for 20 hours! Little brown bats are nocturnal. They sleep in the day and stay awake at night.
