Document Summary

The organism bears a superficial resemblance to another species or model. Similarity in appearance between 2 species arising by natural selection: implies benefit to one or both species. Many prey suddenly flash bright colors or eyespots to startle predators: e. g. Aposematic coloration: warning about prey defense to potential predators, both prey and predator benefit in this situation. ; poisonous frogs, coral snakes, monarch butterflies, etc. Batesian mimicry: a harmless, edible species (the mimic) evolves similarity to a harmful or unpalatable species (model, only the mimic benefits in this situation. ; wasp and wasp mimics: henry bates. ; monarch and viceroy butterfly: fritz mueller. Worked in the amazon 3 decades after bates. Both mullerian and batesian mimicry may be acting at once within a group of species: both species benefit too because a predator will most likely avoid both species.
