Will Tuna Die if It Doesn't Sleep? Let Me See Who's Saying Nonsense
Species Chat VOL001
Do you ever wonder,
There is no bed, and there is no bedroom,
How do animals sleep?
Kneeling horses,
Solitary flamingos,
Hanging bats and so on,
It can be said,Baseline no 6Indeed.
Today we talk about something different,
For example… floating whales.
Although it is said to be sleeping,
In fact, they are half asleep and half awake
Half a brain is sleeping, and half a brain is counting breaths
And incidentally, feel the surrounding environment.
Unlike humans,
Whales and dolphins have autonomous breathing,
Therefore, they cannot fully sleep.
Because the breath-holding time is different for different whales,
Their sleep time will also vary.
Speaking of marine animals,
We cannot help but mention a widely spreadMisconception——
Tuna does not sleepBecause they need to move to obtain oxygen,
Otherwise they will suffocate to death.
Tuna uses impact respiration
Only by constantly moving can they let water enter their gills,
Thus bringing oxygen.
But this does not mean they don't sleep,
They just sleep in a way different from humans——
They are actually sleeping while swimming
Compared to them,We humans are much easier to sleep
So don't stay up late, go to sleep quickly!
