Sharks are cool because they have lived for millions of years almost without change. Most creatures change a lot over millions of years. They don't blink. Sharks can swallow huge objects whole, too! In Finding Nemo, Bruce and his friends tryed to not eat fish, so that they could have friends. But when he smelt blood his instincts told him," I gotta have some fish! Get the fish!" He just couldn't help it. That is just the same to real sharks. My sharks at home are Dwarf sharks. They will sometimes bite but are like Bruce. Sharks love seals and mistake people on surf boards for them. Sharks have hundreds of pups every couple years. Sharks are very fasinating creatures when you come to think of it. They can smell blood when it's miles away. Sharks can roll their eyes to the back of their head. These are the reasons why they are sooooo cool!
