Some vulnerable juvenile marine creatures have a clever strategy to escape being eaten. They resort to relative invisibility by making themselves transparent. But that can't work for their eyes because when you collect light in order to see it, you end up leaving a dark spot which predators are able to see. Some shrimp larvae have crammed their retinas with assemblages of tiny orbs or nanospheres which can bend light from the surroundings back out into the direction of their gaze. So what do you think? Will it work or won't it? I guess time will tell Brenda Burchill there at the University of Cambridge.
