  5. Why I Chose Sharks I chose sharks because they haven’t changed from prehistoric time to present. How they adapted is great. The very word, shark, strikes fear in the hearts of the bravest men. They are a living fossil. They are one of the scariest fishes ever. What they do to survive is really cool.
