IPA: //ˈkaʊntərˌʃeɪdɪŋ//
KK: /ˈkaʊntərˌʃeɪdɪŋ/
A type of coloration in animals where the parts that are usually in light are darker, and the parts that are usually in shadow are lighter. This helps the animal blend into its environment and avoid being seen by predators.
The deer has countershading, making it harder for predators to spot it in the forest.
Countershading is formed from "counter-" (meaning against or opposite) and "shading" (from Old English "sceadu", meaning shadow). The term describes a coloration pattern in animals where the upper parts are darker and the lower parts are lighter, providing camouflage against predators by counteracting the effects of light and shadow.
Think of 'counter' meaning against and 'shading' referring to shadows — this helps you remember that countershading is a way to use color to blend in with light and shadow.
