Camouflage and mimicry in animals

In short: Animals use camouflage and mimicry as survival strategies to escape predators or hunt more successfully themselves. Both strategies evolved over long evolutionary periods through natural selection.

In more detail: Camouflage means blending with the surroundings, while mimicry means imitating another species or object.

In detail

• Colour camouflage: Many animals adapt their body colour to their habitat, like the ptarmigan’s winter white plumage.
• Shape camouflage: Some insects resemble leaves or twigs so closely that they become nearly invisible.
• Batesian mimicry: Harmless species imitate the appearance of dangerous species to deter predators.
• Müllerian mimicry: Several genuinely dangerous species develop similar warning patterns, reinforcing the learning effect for predators.
• Colour change: Chameleons and cuttlefish can actively and quickly adapt their colour to their surroundings.
• Hunting camouflage: Predators like tigers also use camouflage patterns to sneak up on prey undetected.
• Limits of camouflage: Movement, scent, or heat signature can defeat camouflage despite a perfect colour match (evolution-grundlagen, nahrungskette-und-oekosystem).
