    Sharks are colourblind new research finds

    Wearing a white or light blue wetsuit could protect you from a shark attack,
    suggests a new study that found the predators are colour blind.

    Researchers discovered that the eyes of sharks, including bull and tiger
    sharks, are not designed to distinguish different colours and so they see
    the world in black and white.

    That means against the light blue of the sea, it would be better to wear light
    coloured swimwear in order to reduce the contrast with the water.

    The study backs up statistics from the International Shark Attack File (ISAF)
    which shows that the vast majority of attacks happen to divers and surfers
    wearing black wetsuits.

    The team at the University of Western Australia and the University of
    Queensland examined the eyes of 17 species of shark including bull sharks,
    tiger sharks, reef sharks and Port Jackson sharks.

    They found that their retinas had only one kind of cone – or light detector –
    that was only able to detect light or dark. That means a red apple would be
    just a dark shade to them.
