🇺🇸 Batesian mimicry is the phenomenon by which two or more species are similar in appearance, but only one of them is armed with defense mechanisms against predators (spines, stingers, toxic chemicals or even unpleasant taste), while its apparent double lacks these features. The second species has no defense other than resemblance to the first, which confers protection, since predators associate resemblance with some previous bad experience. Batesian mimicry was named after Henry Walter Bates,
