Grasshoppers are green. Some ants are brown. Beach crabs are the same colour as pebbles. The leafy sea dragon with its colourful flowing appendages blends into its environment of undersea plant life. The tiger’s stripes form contrasting patterns of light and dark, allowing the tiger to meld into its surroundings as it stalks through the long, tall grass. In biology, camouflage is a well-known device used by animals to avoid detection or to hide their identity.
Stripes go every which way when a herd of zebras congregate, making them more intimidating and confusing to lions and cheetahs. Alaskan snowshoe hares change colour with the seasons – brown in summer and white in winter. Cuttlefish can change their colour in seconds and emit rapid, pulsating displays to hypnotize their prey.
It looks just like a twig – until it moves. The praying mantis is the same colour and shape as its habitat.

The squid turns on its light-producing organs when the sunshine penetrates the water and hey, presto! It’s invisible from below.
