The great white shark is legendary for the fear that it installs in the human imagination, but they are far less dangerous than we perceive them to be in reality. The White shark is thought to be one of if not the most dangerous shark in the Ocean. The bloodthirsty image that Hollywood portrays the Great white to be is brought about by movies and television but most of all the movie series Jaws. Great White Shark attacks are rare, even though people swim in close proximity to them. The Great White is said to be the king of all sharks, and it’s one of the oldest, most adaptable creatures. Learning about sharks will be more helpful and learning how to avoid shark attacks because lack of knowledge about the white shark, leads the average person to think that the shark prays on humans and sharks rarely attack humans.

I have organized my paper into four main sections. In the first section I discuss the scientific classification of the white shark. In the second section I will talk about anatomy and appearance of the White Shark, which includes from the description of the White Shark color to the reproduction system and habits. In the third section I will go over the Ecology and behavior of the White Shark, the fourth and last section will cover the relationship of humans and the Great White.

Scientific Classification. “Carcharodon carcharias” known as the White Shark is part of the Animalia Kingdom. Animal is Latin for “having breath”. The White Shark is part of the Chordata Phylum, and the Chondrichthyes class. The Chondrichthyes or cartilaginous fishes, which have paired fins, scales, a jaw, a series of chambers in its heart, and a cartilage skeleton rather than bone. The order and family of the White Shark are lamnidae and Lamniformes.

The Anatomy and Appearance. The White shark is known for its torpedo-shaped body, its pitch black eyes, and a crescent-shaped tail fin that has a keel on each side. Great white sharks swim very stiff like a tuna. Great whites are thought to be one of the world's largest and most dangerous predatory fish. Though massive, the great white is not the biggest shark. This classification goes to the whale shark, which is not considered a predatory fish. The White Shark has an extremely complex circulatory system; they conserve body heat by swimming constantly, therefore the heat is distributed throughout the White Sharks body at a temperature that is higher than the surrounding water. This allows the shark to be more active in colder water.
Great White Sharks has a torpedo-shape body, which gives it superior swimming skills; aided by its powerful tail it can propel them at speeds of up to15 mph! The white sharks liver can take up 24% of their body weight, they also have the ability to lurch out of the water. The White Shark gets its name from its all-white belly, its dorsal fin color ranges from pale to a very dark gray but will vary depending on lighting, or watercolor, or visibility.

The White Sharks color scheme is actually useful in hunting its prey, it usually strikes its prey from below and the top color of the shark provides kind of a camouflage when blends in with the water, enabling it to approach the prey undetected. Great White Sharks are known for their teeth, its large mouth contains huge, sharp multiple rows of teeth, about 3,000 of them. When the shark moves in to bite its prey, its jaws extend forward as its head recedes back. The mechanics of the sharks bite is that the lower jaw strikes first, and then the upper jaw descends. Great Whites are thought to use its teeth in the same manner that we as humans use our hands. The White Sharks teeth have about ten to fifteen degrees of flex which makes its jaws like a pair of forceps. The average weight of the White Shark can be about 5,000 pounds or more, and one of the biggest White Sharks to be recorded on record was about 23 feet, and weighing more than 7,000 pounds, yet

Bull Shark Research Paper

Fish (Carcharhinus leucas- Bull shark) Ecological niche: The bull shark is able to live in saltwater and freshwater. The average shark must retain salt in its body to survive. If not, its cells will rupture causing death. When entering freshwater, because of osmosis, water would rush into the shark's body, and disturb the balance of salt and water. The bull shark is able to retain salt, and remove excess water through its kidney. Because of this, bull sharks, if moving into freshwater slowly, can…

Shark Attack Research Paper

We can’t blame sharks for attacking human beings. They have an instinct to eat, and we happen to be edible. There are many ways to prevent shark attacks, and also many ways we are helping them to attack us. Some of the ways we make it easier to attack swimmers and surfers, and even just waders are feeding the sharks, taking away their food supplies, swimming in the water they are also in, and taking more and more of the ocean. Feeding Sharks may be partly to blame for the rising death tolls.…

Bull Shark Research Paper

I will be writing about a species of shark called Bull shark. It is commonly found in warm shallow waters along the coast and rivers; bull sharks are known for being aggressive. They can also live in both saltwater and fresh water. Bull sharks have developed special adaptations, such as the way their kidneys function and special glands near their tail that help keep salt in their bodies even when they’re in freshwater. Females can't give birth until the ripe old age of 10 years old, which would be…
