Detailed explanation-1: -Snow-dwelling animals often have white fur that helps them conceal themselves against the constant wall of white. Many animals possess scattered patches of varying colors that help them blend into the jungle environment; many predators use this technique to great effect.
Detailed explanation-2: -Some poisonous snakes and frogs are brightly colored. Bees, which are known for their stings, often have bold stripes of yellow and black. Predators may avoid these animals because they have learned to associate bright colors with pain.
Detailed explanation-3: -Camouflage, also called cryptic coloration, is a defense or tactic that organisms use to disguise their appearance, usually to blend in with their surroundings. Organisms use camouflage to mask their location, identity, and movement. This allows prey to avoid predators, and for predators to sneak up on prey.
Detailed explanation-4: -Some organisms imitate the protective coloration of others. This phenomenon is known as mimicry. A harmless animal may display the same warning coloration as a dangerous or inedible one in order to deceive predators into reacting as though the benign animal had the same defenses as its model.
