Camouflage is the phenomenon on blending of the animals with the surroundings or environment due to similar shape, marking or colour so as to remain unnoticed for protection against predators or aggression.
Leaf-like insect like grasshopper is green in colour having a flattened body with irregular yellowish spots on it. It resembles a green leaf thereby camouflaging to avoid predators.
A stick insect has slender, dull coloured body and resembles a twig. It is extremely slow in its movements. It conceals itself in small twigs of plants in order to protect itself from predators.
