The Fascinating facts about Dolphin’s sleep

Dolphin’s sleep

Have you ever slept with half of your mind awake? If yes then you might consider it a disease or sleeping disorder. But this phenomenon is normal in dolphins.

They sleep with half of their mind activated. While sleeping, one half of their mind is in deep sleep and the other one remains active. The main reason behind this approach is breathing.

This type of sleeping phenomenon is known as Unihemispheric sleep. Where an organism goes into sleep with a partial mind. Unihemispheric sleep doesn’t exist in humans. In addition to dolphins, few other animals also follow this kind of sleeping pattern.

Dolphins and Breathing

Dolphins find it difficult to breathe underwater. Therefore, they have to reach the water surface, every time they want to inhale oxygen.

Then after every inhale they have the capacity to hold breath for around 8 to 10minutes on average. This time frame varies from species to species. This unique mechanism of dolphins makes them a species of animals who follow the pattern of Unihemispheric sleep.

Along with breathing assistance, Unihemispheric sleep has a number of other advantages. Which makes the lifecycle of dolphins much easier and ensures them a quality life underwater. Along with their mind, dolphins use to keep one eye open too.

In a nutshell when a dolphin sleeps, half of its body is at rest while the other half is active.

The watchdog

We all refer to media, whenever we use the term watchdog. But dolphins have defined the territory for media to work. They have bound media to act as a watchdog at ground level. Because underwater they perform this task themselves.

Along with their unique mechanism of sleep, they possess the energy of staying active for more than two weeks. The capability of staying active and observing the environment for continuous 15 days was not just observed but experimented back in 2012.

Two Stomachs

Just like the unique sleeping system, Dolphins have two stomachs too. One works as a storage for food, while the other is for digestion. Their weight ranges from 9 pounds to 11 tons which is more than 900kgs. Dolphins can swim up to the maximum pace of 54 miles per hour. Because if they swim faster than this, it hurts.
