Luckily, sharks have developed a special feature that enables it to replace its missing tooth. They have developed rows of teeth, each tooth moving up to replace the missing one. A whole broken row of teeth can be replenished, just like a conveyor belt. Each tooth, though, has a different shape, changing according to its necessity. The great white has triangular, serrated-edged teeth anywhere from one to two inches long. With this feature, the shark is able to tear through the flesh for its meal.

There are many shark sanctuaries set up in the ocean to protect them. They can go there and live without having to worry if they will get caught in a net or get their fins cut off. In many countries there are bans on Great White Shark products. There are many projects in effect for protecting Great White Sharks(Institution, Smithsonian). Great white sharks are illegal to hunt because they are endangered. They also have a short life span of about sixty years, but very few make it to even thirty. There are many signs that say the great white population is increasing slowly but steadily(Institution,
