In camouflage, the external appearance of the animal merge with the background, so it's not recognisable. It is characterised by the disguise, in which entire insect looks like a specific object, like a leaf or a twig, that predators overlook.

Praying mantis, same green colour, as that of the leaves, gets easily camouflaged.

A Batesian mimicry is a form of mimicry, typified by a situation where a harmless species has evolved to imitate the warning signals of a harmful species directed at a common predator. The monarch butterfly is poisonous when eaten and the viceroy butterfly is not. Animals that eat butterflies sense that the monarch butterfly is poisonous by its bright orange colour. The viceroy butterfly takes advantage of this coloration to avoid being eaten.

The Dendrobates pumilio is also called as the strawberry poison dart frog, is a species of small poison dart frog found in Central America. Its skin colour is a warning for the poison on it.

Echolocating animals emit calls out to the environment and listen to the echoes of those calls, that return from various objects near them. They use these echoes to locate and identify the objects. It is common in bats and dolphins.
