Nonfiction RR: Sharks

               The book Sharks by Janine Amos is a great book that teaches us about some parts of sharks, what helps them swim, how they hunt and many other things. It explains that sharks have lived on Earth for 400 million years around the times of the dinosaurs. They come in many different shapes, sizes, and colors but they're all very good hunters. The fastest is the Mako shark it can swim 45 miles per hour and the biggest shark is the Gentle Whale shark which weighs as much as two elephants. Most people are scared of sharks because they think that all sharks eat people but the only sharks that actually eat people are the Great white, the bull shark, and the tiger shark.
      According to the text the great white shark are giant hunters.he text explains that, "They feed on animals such as sea lions and seals, as well as on smaller sharks, and people". This means that the great white shark can pretty much eat anything it wants. Also, the text says,"Newborn great whites are already 5 feet long" which is already giving them an advantage to be able to attack most fish and people. The text also let's us know that it's really easy for a shark to hunt because their senses are better than ours. What also might give a shark and advantage to attack people is that they can sniff out blood half  mile away.
      Others sharks like the blue shark swim a lot the book tells us that,"One blue shark made a trip of almost 4,500 miles from New York to Brazil". The reason that sharks need to swim a lot is because most of them don't have swim bladders so if they stop swimming they'll sink. Luckily, sharks are very good swimmers, they're fins help them steer, and they're fins help them keep balance.
       Overall sharks are very interesting creatures and not all of them are interested in hurting/attacking/eating humans but just like us they need to eat food.
