Overfishing can have a dangerous effect on sharks. The whale shark, for example reached maturity at the age of 30 before they start reproducing! Unfortunately many sharks are caught at such a large scale and so often, many sharks don’t reach maturity to help repopulate their numberView attachment 562963

Sharks can use heartbeats to track their prey. Sharks have nodules on their noses about the size of a pimple, called ampullae of Lorenzini. These nodules sense electricity, so the electrical pulses that come from a beating heart can act like a beacon for nearby sharks
 
A common myth is that sharks don’t attack in the middle of the day. And that may be true — but it’s likely because most beachgoers get out of the water to rest or eat at lunchtime, so there aren’t as many people around to cross paths with sharks. Sharks don’t follow the same three meals-a-day eating schedule as humans, they eat when they find food, no matter what time it is

You can’t see a shark’s ears, but that doesn’t stop it from being able to hear you from more than two football fields away. That’s because sharks only have inner ears, which they use to track the sound of their prey from lengths of more than 800 feet (244 meters)
