11. They go through over 1,000 teeth
At any time in their life, a great white shark can have up to 300 teeth, which are arranged in seven rows. Each tooth is pointed, razor-sharp, and up to three inches long. The teeth aren’t strong, however, and they come out pretty easily. In order to reuse the calcium, the shark will swallow the teeth that fall out as often as possible.
10. They can live over 100 years
The ocean’s most feared predator lives for a long time. Until 2017, the generally accepted estimated lifespan of the great white shark was 70 years. According to a National Geographic article published last year, however, a new and more accurate method of measuring the ages of sharks shows that many shark species may live decades longer than previously thought.
9. They have very strong senses
Great whites have 6 highly refined senses of hearing, touch, taste, sight, smell, and electromagnetism which I’ll tell you more about in a bit. While sharks have had millions of years to develop these senses, the sense of smell of a great white, is exceptional! Smithsonian Ocean reports that a great white can smell a single drop of blood floating in 10 billion drops of water.
8. Largest predatory fish
Although great whites are not the largest shark species, (that would be the whale shark), they carry the distinction of being the largest known predatory fish on Earth. They eat marine mammals that weigh several hundred pounds or even larger on a regular basis.
7. They have a 6th sense
Despite their remarkable sense of smell, and ability to detect chemicals, it’s not usually the primary hunting tool of a great white shark. Instead they find food using electroreception. They are extremely sensitive to electric fields and can detect a charge from a single flashlight battery connected to electrodes 16,000 km apart.
6. They roll their eyes
To protect their eyes from getting damaged, great whites roll them into the back of their head whenever they’re attacking. Their eyes don’t have protective membranes or eyelids; therefore, great whites can’t close their eyes. Instead, they roll them back, and are unable to see their prey while attacking.
5. They must move constantly
Great white sharks breathe using a process called ram ventilation. Water “rams” into their mouth as they swim and exits through the gills, extracting the necessary oxygen. If a great white stops moving, it will therefore stop breathing and die.
4. They migrate great distances
These large sharks are highly migratory. Besides having to swim constantly to stay alive, great white sharks travel great distances for seasonal food, for their young and sometimes to congregate in the middle of nowhere for no known reason.
3. Bad Reputation
According to the International Shark Attack file, great white sharks are responsible for the most attacks on humans. In the past 400 years, the species has reportedly attacked 314 humans supposedly without provocation. 80 of the attacks were fatal. However, great whites are extremely curious animals and are attracted to splashing and noise.
2. They aren’t picky eaters
Some animal species have a reputation for being willing to eat pretty much anything, and the great white shark is one of them. They prefer tuna, dolphins, whales, seals, sea turtles, and seabirds, but will eat fish, including other sharks. Sometimes, great whites even eat sea snakes and crocodiles.
1. Their behavior is largely a mystery
Scientists and researchers have been unable to fully understand some of the great white shark’s behaviors. For one, the mostly solitary animals intermittently reunites with other members of its species. Great whites meeting and traveling in groups typically avoid dominance battles and conflict. In certain places, however, distinct hierarchies exist.
