【Record 20】Are whales really not fish? Why does a whale need to breathe with its lungs, so what about it sleeping? Will it drown?

It turns out that the whale used to live on land, but due to environmental changes, it entered the water to live, which retained the characteristics of using lung breathing and viviparity, so it is really not a fish. [I want to be quiet]

Whales live in water all their lives, and they can stay underwater for a long time, and some can even stay for an hour.

So the question is, since the whale cannot go ashore and also needs to be ventilated at intervals, what should it do when it sleeps? Will it drown? [Nose picking]

Because whales need to consciously open their fumaroles for ventilation, some speculate that whales only let half of their brains rest while they sleep, while the other half stays awake to control their breathing. So if the whale oversleeps or is knocked unconscious, there is a real possibility of drowning.

Hahahaha, it is also possible that whales have evolved the habit of not sleeping well, and they just need to take a nap from time to time. [Laughing and crying]
