Scientists have found that sperm whales will go to sleep in a vertical state within about 15 meters below the surface of the sea, just like driftwood, and their sleep time is really very short compared to humans, between 6 and 24 minutes, equivalent to human napping. After the sperm whale breathes on the surface of the water, it will go to sleep under the sea surface in a closed state, and it is estimated that the sperm whale sleeps for only 7% of its lifetime.

With the conservation of sperm whales, their numbers are steadily increasing. #I'm coming to science ##今天2022世界海洋日 #
