In Western Australia for instance, statistics show that when the water reads at 18 to 20 degrees, great white sharks are more prone to attack humans. Lastly, the water temperature also affects a shark’s behavioral pattern. Turned out, sharks cannot differentiate the two therefore, proving the theory to be true. In a test conducted by experts, they observed how a shark’s retina will be able to recognize the visual motions of a seal and a swimmer paddling with a surfboard from the perspective of viewing things below the water surface. This brings us to another possible theory why sharks attack humans - m istaken identity.īased on research, sharks (specifically the great whites) also bite on humans because they often mistake us as seals, a.k.a their primary prey. However, when the water is murky, their vision becomes dull, which makes it challenging for them to see clearly and hunt for their prey during stormy days. Their impressive eyesight is ten times much better than humans, and this allows them to hunt in both daylight and low light conditions. Sharks have good vision and sense of smell. This is the reason why sharks ‘hit and run’, and most victims survive the attacks. Humans consist of a lot of bones, see, and sharks don’t really like to consume that. Once they have a bite, it’s seldom they would go for another. The shark’s goal: to have a test bite, not to eat. Sharks may circle on a person because they’re curious and they want to find out if they’re edible. Surprising as it seems, smart dogs and toothy sharks have one thing in common, and it is by how they investigate things with their mouths. So why do you think some sharkies would chomp on surfers? I t’s because they’re curious. They have a slow digestion process which makes them very selective of their food, a reason why they often eat seals and sea lions - marine mammals that are high in fat content. Sharks are designed to hunt, but you should know that humans are not part of their diet.
They provide the scraps for the organisms to eat and help regulate the ocean population by preying on the weak. Sharks, similar to orcas, are ocean predators that play an integral part in the ecosystem. The Sharkiest Surfing Locations in the World.
