How do whales sleep (detailed introduction)

Whales are a type of marine mammal, and their sleeping patterns are very different from ordinary land mammals. Here's a closer look at how whales sleep:

Sleeping style:

Whales are animals that regularly surface to breathe air, so they don't fall into deep sleep like land mammals. Whale sleep is a special type of unilateral hemibrain sleep, also known as hemibrain sleep.

Half-brain sleep:

In hemi-sleep, half of a whale's brain remains awake while the other half goes dormant. This way of sleeping allows whales to keep swimming and breathing while sleeping, ensuring that they are not too deep asleep to come up to the surface to breathe.

Eye status:

When whales sleep, they usually close one eye while keeping the other open to monitor the surrounding environment and ensure that they can detect potential danger in time or maintain contact with their companions.

Sleep cycle:

Whales have flexible sleep cycles, allowing them to take multiple short naps at different times to meet the rest needs of their bodies and brains. This way of sleeping ensures that whales can survive and reproduce in the ocean without being put in danger due to unilateral hemibrain sleep.

In general, whales rest in the water with half-brain sleep, ensuring their basic survival needs in the sleep state, such as breathing and alertness. This unique way of sleeping allows whales to adapt to life in the ocean, while also ensuring they remain alert and responsive when needed.
