Great White Sharks mostly attack Daytona Beach, Florida. This happens because the sharks migrate down to warmer waters. Sharks do not normally hunt humans. When they do attack a human, it is usually a case of mistaken identity. Shark sometimes mistake humans for its natural prey, such as fish or a marine mammal or sea turtle, and most often will release the person after the first bite.

However, they also have poor spatial acuity, which essentially means their vision is more blurred than humans."Do Sharks Really Mistake Humans for Seals? Researchers Test 'mistaken Identity' Theory."

Shark Anatomy
The great white shark’s scientific name is Carcharodon carcharias, which means "ragged tooth" in Latin and shows that this shark's teeth have always been an important trait. Pectoral fins sharks use these fins to lift and steer them while they swim. Great white sharks are chondrichthyes which means their body is made out of cartilage. Pelvic fins; these keep the shark stabilized while it swims. on male sharks, attached to the pelvic fins are claspers, which are necessary for the reproduction process. When it comes to the shark having the ability to propel itself through the water, they utilize what is called the caudal fin. This fin, also known as the tail fin, has an upper and lower lobe. The upper lobe of the caudal fin produces the majority of the shark’s thrusting abilities. The tail fin is one of the most important parts of the entire shark anatomy. Therefore, the anal fin is present to provide additional stability to the sharks that possess them. The anal fin is located between the pelvic and caudal fins on the bottom, or ventral, part of the shark. Located on the side of a shark’s head are five to seven gill slits; in order for gas exchange to occur correctly, water has to consistently flow over the gill slits. Once the shark allows water to enter their mouth, it goes through the pharynx, over the gills and finally leaves through the actual gill slits.
