Shark attacks on humans are rarely because the shark wants human meat. The attack is often a case of mistaken identity. A surfer at the water’s surface may look like a sea lion or turtle, and the splashing attracts the shark’s attention. Sharks, being very curious animals, immediately investigate any unusual sights and sounds. They will bump into things or even bite items it doesn’t recognize. This behavior is obviously a great health risk to any surfer or swimmer that catches the sharks attention.
