"The second pattern, "Diverter", designed for surfers, is the opposite in terms of visibility, patterned with bold black-and-white stripes. Although sharks are colour blind, they have very sharp perception when it comes to shading. The patterning on the Diverter suit is based on boldly patterned sea creatures that use their banded colouration as a warning to predators that they are venomous; and, indeed, sharks tend to avoid eating striped fish. Diverter presents the wearer as unpalatable — and possibly even toxic — to a hungry shark."
Of course if there were any Lions on the beach looking like a Zebra might not be a good idea :)
