Great whites don’t attack humans on purpose but confuse them with seals because they’re colour blind and can’t see in detail, study using ‘shark vision’ finds. Great whites are often portrayed as ruthless human killers, but a new study suggests shark attack victims are simply the subject of mistaken identity.
Why do sharks think humans are seals?
The team also found that seals and sea lions with their fins out looked similar in shape to human swimmers and surfers. These findings show that great white sharks may find it hard to visually distinguish humans, seals and sea lions from below, supporting the idea that shark bites are cases of mistaken identity.
Do sharks think we are seals?
Swimmers beware: Hungry sharks do think you’re food. Young white sharks, which are responsible for the majority of attacks on people, can’t distinguish between humans and seals, according to new research.
Do sharks confuse people for seals?

Do great white sharks mistake humans for seals?
White sharks can easily mistake swimmers or surfers for seals. Our research aims to reduce the risk.
What do sharks see humans as?

Do sharks think people are food?
“We do know that sharks don’t like to eat people,” he said. “Studies show they respond strongly to the smell of seals and fish, but not humans. The trouble with sharks is that they are inquisitive and when checking out a potential prey item they typically come up and have a nibble.

Why are sharks afraid of dolphins?
Made of very strong and thick bone, dolphin snouts are biological battering rams. Dolphins will position themselves several yards under a shark and burst upwards jabbing their snout into the soft underbelly of the shark causing serious internal injuries.
Why do sharks mistake humans for animals?
Sharks have extremely powerful vision and are unlikely to mistake a surfer for a seal. However, in turbid waters, the erratic motion of humans and the contrast between their skin and their attire can confuse sharks.
Will a seal bite you?

Are great white sharks friendly?
5) Whilst many think of these beasts as fearsome man-eaters, humans aren’t, in fact, on the great white’s menu. Phew!

Why do sharks not eat humans?
