The Cuttlefish makes a killing with colour
Cuttlefish have an extraordinary, and almost instantaneous, control over their appearance. They can produce hundreds of distinct patterns, which they use for camouflaging, courting mates or startling predators. One dynamic pattern, where thick black and white bands flow rapidly over the skin of the cuttlefish as it near its prey, is somewhat of a mystery. Why, just as the cuttlefish approaches an unsuspecting target, should it switch from camouflage to a highly conspicuous display?
