A shark deterrent wetsuit

I wanted to practice my listening so I went to Ted.org and looked for a interesting video. I really like animal documentaries so I was looking for a video about animals. Then I founded this video about a surfer named Hamish Jolly, that wanted a wetsuit that would deter a curious shark from mistaking him for food. A lot of scientists went looking for a solution that would stop the shark attacks. They needed a scientific breakthrough that would potentially save lives. So they went to look for people that know a lot about shark vision and shark neurology. They research led to the university of W.A. with the oceans institute. Professor Nathan Hart and his team told them that predatory sharks see in black and white. They were thinking about using these grey patterns and shapes to produce a wetsuit that would descend the risk of a shark attack.

They needed to do a lot of research. First they started to map the physical characteristics of the eyes of the tree main predatory sharks. The great white, tiger and bull shark. Than they tried to understand what that eye could see at different depths, distances, light conditions and water clarity in the ocean. What patterns and shapes would present the wearer of an shark attack where the two most important characteristics. Then they started to use all these scientistic results to build two wetsuits. The first wetsuits was called "don't eat me" wetsuit (the black, white wetsuit on the picture). The second wetsuit they made was called the cryptic wetsuit (the blue wetsuit on the picture). The don't eat me wetsuit was made to distract the shark. The cryptic wetsuit was made to hide the wearer in the ocean.

At the end they needed to test these suits. Of course they couldn't test this with humans so they perforated a large drum that was stuffed with a lot of bait and had the wetsuit around it. These drums were putted nearby a white or tiger shark and at a place where they could observe there reactions of the sharks on the wetsuits. After the tests they had an amazing result. The sharks didn't found the drum or where just not interested. So it was an amazing invention. 

I hope it will stop the shark attacks so more people could participate in surfing. And I think the wetsuits look also very cool so it won't be a problem to wear them.
