Based on a breakthrough discovery that sharks are colour-blind, one wetsuit, labelled the “Elude”, is designed to camouflage a swimmer or diver in the sea.Based on a breakthrough discovery that sharks are colour-blind, one wetsuit, labelled the “Elude”, is designed to camouflage a swimmer or diver in the sea.
At the other extreme, the “Diverter” sports bold white and dark-blue stripes, and is intended to mirror nature's warning signs to ward off any potential shark attack.At the other extreme, the “Diverter” sports bold white and dark-blue stripes, and is intended to mirror nature's warning signs to ward off any potential shark attack.

“Many animals in biology are repelled by noxious animals – prey that provide a signal that somehow says ‘Don't eat me’ – and that has been manifest in a striped pattern.“Many animals in biology are repelled by noxious animals – prey that provide a signal that somehow says ‘Don't eat me’ – and that has been manifest in a striped pattern.

The five fatal attacks in WA waters in just under 12 months, which earned the state the unwelcome tag of shark attack capital of the world, prompted the research into the suits more than two years ago.The five fatal attacks in WA waters in just under 12 months, which earned the state the unwelcome tag of shark attack capital of the world, prompted the research into the suits more than two years ago.
The designs have been tested in the water with tiger sharks – but not on humans – mainly in waters off the northern WA coast near Ningaloo Reef.The designs have been tested in the water with tiger sharks – but not on humans – mainly in waters off the northern WA coast near Ningaloo Reef.
Testing will continue this summer with great white sharks in the waters off South Australia and South Africa.Testing will continue this summer with great white sharks in the waters off South Australia and South Africa.
Hamish Jolly, from SAMS, said the results so far warranted the suits going on sale immediately.Hamish Jolly, from SAMS, said the results so far warranted the suits going on sale immediately.
"We now know what these big predatory sharks can see, and what we have done is convert that science into a marketable technology," Jolly said."We now know what these big predatory sharks can see, and what we have done is convert that science into a marketable technology," Jolly said.
