Almost all animals need to sleep to stay healthy. But sleeping can be dangerous. Animals have many different ways of sleeping that help them stay safe. | |
![]() | Sleeping Upside Down Almost all bats (蝙蝠) sleep upside down. They hang (挂) from a tree or from the ceiling of a cave. Up high, bats are safe from most other animals. If they are in danger, they just fly away. |
![]() | Sleeping the Least (最少) Giraffes sleep the least. They lie down when they sleep. Every few hours, they sleep for about ten minutes. Giraffes are not safe if they sleep for a long time. |
![]() | Sleeping with Half the Brain (大脑) Some ducks sleep with just half their brains. These ducks often sleep in a line. The ducks at both ends help keep the group safe. They keep one eye open to watch for danger. The ducks in the middle can sleep deeply with both eyes closed. |
![]() | Sleeping Standing Up Horses often sleep standing up. If a horse is lying down, it needs a long time to get up. A horse can run from danger more quickly if it is already standing. |
