The Top Ten Most Surprising Facts About Sharks

Sharks are one of the most interesting animals in the world.
They're insanely interesting, as long as they are admired from a distance!
And we definitely mean more than an arm's length away!
Here is a top ten list of the most surprising facts about sharks:
"1. Sharks generally have about 45 to 50 teeth – but that’s just the “front row” teeth. They also have, on average, as many as seven replacement rows of teeth behind the front row, ready to move into place if a tooth is damaged or falls out. With all the action a shark’s mouth sees throughout its lifetime, an individual might go through as many as 30,000 teeth.
2. Even though we associate sharks with big, sharp chompers, some species barely need their teeth. Whale sharks and basking sharks, two of the largest species, are both filter feeders and have numerous, tiny teeth – a whale shark might have up to 300 rows of teeth .
3. While sharks don’t use sounds to communicate, they do rely on body language. If you’re snorkeling or diving, it’s good to be aware of the body language sharks use to communicate that they’re uneasy. Hunched backs, lowered pectoral fins, sharp movements (in zig-zag or back-and-forth patterns), and diving down to touch the bottom are all good indicators that a shark is feeling uncomfortable.
4. Some large sharks have dramatically longer lifespans than small sharks. For instance, whale sharks (which generally range from 18 to 32 feet/5.5 to 10 meters in length) can live up to 100 years, while the smooth dogfish (with an average length between 2 and 4 feet/0.6 and 1.2 meters) might only live for 16 years."
