In your post you mentioned sharks. And I remembered how in many television programs they say that they are very dangerous and are pitched. I want to say that I do not quite agree with this. Sharks do not always attack people.

Of all the diversity of sharks, only 3% are a threat to humans. The most dangerous sharks are: large white, tiger and gray bull shark.

The rest are either not dangerous for a person or an attack on a person is unlikely.

First of all, such can be attributed to deep-sea sharks, which do not rise when they come to the surface of water visited by humans.
