camouflage
Definition
Camouflage is a biological adaptation that allows animals to blend in with their surroundings. This is an important survival strategy for many animals, as it helps them to avoid predators and to catch prey.
There are many different types of camouflage, and they can be classified into three main categories: disruptive colouration, background matching, and countershading.
Disruptive colouration is a type of camouflage that breaks up the outline of an animal's body. This can be achieved by having patterns on the animal's fur or skin that are similar to the patterns of the surrounding environment. For example, the stripes on a zebra help to break up its outline and make it difficult to see from a distance.
Background matching is a type of camouflage that involves the animal's colouration matching the colour of its surroundings. This can be achieved by having a uniform colouration that matches the background, or by having a colouration that changes to match the background. For example, the chameleon can change its colour to match the colour of the leaves on which it is sitting.
Countershading is a type of camouflage that involves the animal's colouration being darker on the top of the body and lighter on the bottom of the body. This makes the animal appear flatter and less three-dimensional, which makes it more difficult to see from above or below. For example, the flounder has a dark back and a light belly, which helps it to blend in with the bottom of the ocean.
How can the word be used?

Why do animals use camouflage?
AQA Science Exam Question and Answer
Question:
Define "camouflage" and explain its role as an adaptation in the survival of certain organisms.
Answer:
"Camouflage" is a biological adaptation in which an organism's appearance, colour, or pattern allows it to blend into its surroundings, providing protection and increasing its chances of survival.
Role of Camouflage in Organism Survival:
Camouflage is a powerful survival strategy that helps organisms evade predators or avoid detection by prey. By blending seamlessly into their environment, camouflaged organisms become more challenging to spot, making it easier for them to hunt for food, avoid becoming prey themselves, or protect their offspring. This adaptation enables these organisms to have a higher chance of survival and reproduction, passing on their camouflage traits to future generations through natural selection. As a result, camouflaged organisms can better adapt and thrive in their specific habitats, increasing their overall fitness and survival rates.
