Answer:
Animal coloration is the general appearance of an animal resulting from the reflection or emission of light from its surfaces. Some animals are brightly coloured, while others are hard to see.
Some animals, including many butterflies and birds, have microscopic structures in scales, bristles or feathers which give them brilliant iridescent colours. Other animals including squid and some deep-sea fish can produce light, sometimes of different colours.
In some cases colors are used to find the perfect mate. Animals also use colors as warning signals and as camouflage to hide from predators. ... The bright color is a warning that it is toxic and it helps keep predators away.
