Various kinds of mimicry

• Batesian mimicry: resemblance of harmless species to some non-edible species that signals their unsuitability to possible predators

• Müllerian mimicry: resemblance of aposematic signals of different non-edible species

• Peckhamian mimicry: resemblance of predators’ messages to messages of some species, or to some objects, that are harmless to their prey

• Wasmannian mimicry: occurs when the mimic resembles it's host in order to live within the same nest or structure
