Visual warning to predator animals, especially by potential prey animals, of and/or issues associated with being .

Aposematic coloration is seen, for example, in the bright coloration of as well as the all too common black and yellow striping displayed by many . In addition is warning coloration associated with .

Aposematic coloration is based on the idea that predators are capable of , particularly . Thus, a bad experience by a predator with a prey animal of a given, easily discerned color or color pattern will tend to teach that predator to avoid that type of prey animal.

Individual prey animals, in turn, benefit from having predators avoid them. They therefore can benefit from displaying aposematic coloration, and this is so even if such coloration is imperfect, i.e., as particularly can be the case given naive predators. Similarly, it can be useful as well for an organism to display cryptic coloration even if the result is not 100% evasion of .
