Sharks have been on earth long before the dinosaurs were, and are still going strong today with little change. They are apex predators at the top of the food chain and said 2 be the ultimate predator, the perfect killing machine. there are over 350 diffirenet species of sharks, but 3 are the main ones who are responsible for attacks on humans, the Bull shark, the Tiger shark, and my favorite of all, the Great White Shark, king of the ocean.

Sharks rely on their sense of smell to find prey, but also employ sensory pores on their heads to detect electrical fields created by prey.They rarely attack humans unless provoked.

Not only do they have sharp teeth, they have the ability to replace their teeth.

Isn't their skin made of their teeth or the material found in teeth? Although their skin looks smooth, it's like sandpaper and can cut you if you arent careful. Their rows of teeth also slide forward when attacking something.

That sharks and rays are related to each other because they both have cartilage.
