Three Sleeping Whales
👇
Whales don't sleep much. They typically only sleep for 15 to 20 minutes at a time, as this is the length of time that they're able to go without having to come back up for air.
👇
This is one of the adaptations that they've made to their underwater lifestyle.
👇
It's not clear whether whales undergo deep sleep like humans and other mammals, but we can assume that if they do, it's for a very short period of time.
👇
Whales need to always be in control of their blowhole. Without control of their blowhole, water would be allowed to enter into their lungs, and they would not survive.
👇
So if a whale entered into a deep state of sleep such as REM sleep, they might lose control and subsequently.
