Tuna will die if it doesn't swim? Let me see who is talking nonsense

Have you ever thought about

There is no bed and no bedroom.

How do animals sleep?

Wildebeest sleeping standing up,

Flamingo standing on one leg,

A bat hanging upside down or something...

Today we're going to talk about something different.

For example... a sperm whale floating and sleeping.

Although it is sleep,

But in fact, they are in a state of half-sleep and half-wakefulness

Half of my brain is sleeping, and the other half is counting my breaths .

Take a look at your surroundings.

Unlike humans,

The breathing of cetaceans is autonomous.

Therefore, I cannot fall asleep completely.

Because different whales hold their breath for different periods of time,

The times they sleep will also vary .

Speaking of animals in the sea,

We have to mention a widely spread misunderstanding

——Tuna never sleeps .

Because they can only get oxygen by swimming,

Otherwise you will suffocate to death.

Tuna breathes by impact .

Only by swimming continuously can water flow into their gills.

This brings in oxygen.

But that doesn't mean they don't sleep.

They just sleep differently than humans do.

——They actually sleep while swimming .

Compared to them,

It's much easier for us to sleep.

So, don’t stay up late and go to bed!
