Müllerian mimicry

Pronunciation: /myo͞oˈli(ə)rēən/ /milˈi(ə)r-/


A form of mimicry in which two or more noxious animals develop similar appearances as a shared protective device, the theory being that if a predator learns to avoid one of the noxious species, it will avoid the mimic species as well. Compare with Batesian mimicry.
