Mystery Solved: How dolphin swim so fast? Scientist have found out the mystery of how dolphins swim so fast. It was a mystery since the 1930’s. After a lots of observations, experiments, and researches until today; a marine biologist, Frank Fish, discovered the solution of this mystery. He states that when the dolphins swim in circles, they produce enough energy by using their tails to swim fast. Mr. Fish reviewed “Sir James Gray paradox”, which states, that the animal didn’t have the enough muscle mass to produce the necessary energy to swim fast. Mr. Fish needed to find out in his experiment, how to measure the forces dolphins produced during swimming. With the collaboration of Timothy Wei, who studies Olympic swimmers and Terrie Williams, a marine biologist; worked together on a new method to obtain the data they needed without harming the dolphins. They created an experiment with a bubble curtain and laser; and finally they can measure the force. The results proved that dolphin’s tails or fluke, can produce the enough force to swim fast when they swim in circle. Their tails are so flexible and can maintain the speed. And now, the new question is: How they can control the tail? Mr. Fish and his colleagues will find out, but Finally Mr. Fish find the answer of this mystery and clarify the “Gray’s paradox”. I never thought that how dolphins swim so fast was a mystery. This captured my attention while reading this article. Now I understand the science and mystery behind of something that you see normal and natural in this specie and others every day. It was very interesting to see how the scientist’s get together to find out creative solutions in order to obtain the necessary data to prove their theories. Their collaboration was amazing to resolve this mystery. Jane J. Lee. January 15, 2013, www. natgeo.com, January 15,
