How Do Great White Sharks Operate?

       How do Great White sharks work? I don't know, maybe they're all mechanical robots in disguise. I just can't fathom how such a big and meaty animal can speedily and gracefully glide through the water.  The thought of this question came up while I was watching the movie Shark Night.  After thinking of this question I decided to do some research,and this is what I learned.

      The first thing I researched was the Great White's anatomy.  A Great white sharks body is comprised entirely of muscle.  Their bodies do not contain bones.  Instead their whole skeletal structure is made of a tissue called cartilage.  Great Whites are not like other fish because they don't have a swim bladder.  A swim bladder is an adaptation that allows fish to control their buoyancy in the water.  This adaptation basically allow fish to float without moving.  Since Great Whites,or any other sharks, don't have a swim bladder, they must stay in constant motion.  If the shark doesn't it will sink.

      Second, but definitely not the last amazing thing about these swimming natural disasters is the Great White's  teeth.  Great Whites' have two rows of razor-like teeth.  Their first row of teeth is used to capture their prey.  While the second row is used to carve and chew up prey.  These sharks have at least three hundred teeth in their mouth, and if they lose teeth, new teeth replace the lost ones. Each tooth in the shark's mouth are about three inches long.

     These sharks prey on the weak and eat many sea animals.  They wouldn't be able to prey on or track the animals they eat if it weren't for their incredible senses.  Great white sharks have a great sense of smell.  Their sense of smell is so developed that  they can smell a drop of blood up from three miles away.  With their sense of smell they can also determine the approximate location of the prey they are tracking.  These sharks can sense electromagnetic charges in the water.  This adaptation allows them to hunt and find prey.  For example, when this shark bites or attacks prey, it rolls its eyes back so it's eyes aren't damaged.  When this happens it can't see, it is relying on its sense of smell and its ability to sense the electromagnetic waves its prey is emitting.  Some of the animals that these animals eat include sea lions, seals, small toothed whales, and even sea turtles, and carrion.

       In conclusion, Great White Sharks are amazing creatures, that deserve to be respected.  They have been biologically engineered by nature to survive in an aquatic environment, and have very keen senses.  They only hunt other animals such as seals, sea turtles, and sea lions.  They aren't really a threat to humans, because out of the reported shark attacks Great Whites are only responsible for about one third of them, and most of the injuries caused aren't fatal.  These aquatic machines are built to survive, and yet are an endangered species.  So one should ask oneself, is it right that these amazing animals are on the verge of extinction?
