Interesting facts about sharks
So that I can be fast when swimming actively. They are narrow and elongated, and move by means of a strong tail in which most of the muscle is located.

Because they don't use their teeth to chew, but to tear their prey. The prey is then only swallowed in large chunks.
How are their senses?
The sense of smell is extremely well developed. Thanks to scented sachets, sharks can "smell" and react to a drop of blood in seawater, in a concentration of 1: 1,000,000.
Most sharks have their eyes set on the side of their head, so their field of vision is extremely large.
