What is batesain mimicry?

Answer 1

There are two main types of mimicry, which is the adaption by one life form of some of the superficial characteristics of another. The first is called Batesian mimicry, and in this case the mimic is sort of "free riding" on the reputation of the creature mimiced. The other is Mullerian mimicry and here both creatures contribute to the reputation.

Consider two butterflies, the Monarch and the Viceroy. The viceroy's coloration mimics the monarch's. The monarch eats milkweed and the latex in its body is toxic to birds, so they learn not to eat monarchs, and sometimes they pass up viceroys as well.

Now, the viceroy doesn't eat milkweed, so presumably it is a Batesian mimic, just coasting on the monarch's reputation as a toxic butterfly -- BUT -- some naturalists think they the viceroy, though it doesn't eat milkweed specifically, also has a toxic diet and is therefore a Mullerian mimic.

One clear case of Batesian mimicry is the scarlet snake, which is nonvenomous but looks similar to the coral snake, which is.

Answer 2

Batesian mimicry is a form of mimicry where a harmless species evolves to resemble a harmful or toxic species to gain protection from predators. By mimicking the appearance of a dangerous species, the harmless species can reduce the likelihood of being attacked or eaten by predators. This phenomenon was first described by the biologist Henry Walter Bates in the 19th century.
