Why do sharks mistake surfers for 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.
How do sharks confuse humans for seals?
They did this by cleverly manipulating footage of swimming humans and seals as a shark would see it. Sharks likely confuse an oval-shaped surfboard for the body of a seal, as well as a human’s arms and legs for the limbs of the seal, the researchers concluded.

The aqua-blue wetsuit is based around three colors visible to sharks in slightly deeper water. Each color matches a color at a particular time of day, making that part of the suit virtually invisible to the shark. Like the black-and-white suit, this breaks the swimmer’s silhouette and confuses the shark.
