A foreign friend caught a great white shark, and the strange thing is that the great white shark has no former ferocity and is motionless like a doll.
It turned out that the shark had rolled over. When the shark's belly is facing upwards and cannot be flipped over, in order to avoid panic caused by the upside-down visual world, the shark's brain will secrete a large amount of neurotransmitter serotonin, and the shark will gradually become delirious and enter a tonic static state. At this time, the shark was weak and defenseless.
When killer whales hunt great white sharks, they take advantage of this Achilles heel of sharks. Killer whales will knock over great white sharks and then do whatever they want with the unconscious great white sharks.
If you encounter a ferocious shark in the sea, can you turn it over? #打卡挑战局 #
