Two new wetsuits, which could protect surfers from sharks have been unveiled by University of Western Australia scientists.
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, the Courier Mail reported.
More than two years in development, the suits, which retail at 495 dollars, went on sale via online distributor Radiator on Wednesday.
Shaun Collin, from UWA's Ocean Institute, said they had used a mix of scientific discoveries and observations about nature to come up with warning suit designs aimed at reducing the risk to swimmers, surfers and divers.
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.
