According to National Geographic, “Each year there are about 50 to 70 confirmed shark attacks and 5 to 15 shark-attack fatalities around the world. The numbers have risen over the past several decades but not because sharks are more aggressive: Humans have simply taken to coastal waters in increasing numbers.”
The blacktip shark is often found in shallow waters and the tiger shark likes to stay in deep waters. That being said, it is important to be aware that it doesn’t matter where in the ocean you may be. Whether you are surfing in deep waters, or swimming in shallow waters, sharks are everywhere and they never sleep (seriously…they don’t).
There are many things you can do to reduce your odds of being attacked by a shark. For one, make sure you stay in groups; sharks are more likely to attack when they see someone alone. Sharks can detect the smell of blood from miles away, if you have a cut, or cut yourself in the ocean, remove yourself immediately! Try and avoid being in the water after the sun goes down, the sharks come out at night to feed. Most importantly, do not provoke a shark by splashing or making abrupt movements underwater.
When a shark loses its teeth, they replace themselves within 24 hours.
The largest shark is the whale shark; it can grow to 60ft long.
The smallest shark is the deepwater dogfish shark; it only gets to about 8 inches long.
