Wikipedia definition
2. AposematismAposematism (from apo- away, and sematic sign/meaning), perhaps most commonly known in the context of warning colouration, describes a family of antipredator adaptations where a warning signal is associated with the unprofitability of a prey item to potential predators. It is one form of "advertising" signal, with many others existing, such as the bright colours of flowers which lure pollinators.
