disruptive coloration
Quick Summary
Disruptive coloration is a type of camouflage that breaks up the outline of an animal's body, making it harder for predators or prey to recognize its shape. This is achieved by using patterns that do not match the animal's contour. For example, a fish might have dark "saddles" that disrupt its outline, or stripes that run along its body.1
This type of coloration is particularly effective when animals are in groups, like schools of fish. The combined disruptive patterns of many individuals can create a confusing spectacle, making it difficult for a predator to target a single animal. Disruptive patterns can also help conceal an animal's movement, as seen in banded snakes moving through tall grass. This strategy is one of several ways animals use coloration for survival, falling under the broader category of optical functions in biological coloration.12
