How do humans protect shark belts?

A new high-performance swimsuit developed by imitating shark skin will be worn by top athletes in Athens this week.

This revolutionary new fabric was developed by Speedo, which is the result of four years' research and development from the study of shark skin in the Natural History Museum.

This new swimsuit named "Fast Skin FSII" can improve the swimmer's speed by reducing the passive resistance in the water, which is 4% more than the second best swimsuit.

Under the guidance of Ollie Keliman, a fish expert in the Natural History Museum, the skin texture and movement of sharks in water were studied.

Tiny "teeth" cover the skin surface of sharks. These "teeth" have different shapes and positions all over the body to control the water flow.

With these discoveries, Speedo has created a complete "body skin", using different fabrics in different parts of the body, which is the first swimsuit for men and women and for specific swimming strokes.
