What is known as the mimicry where two or more unpalatable species resemble each other?

Mullerian mimicry refers to a scenario in which two or more unpalatable or harmful species evolve to resemble each other. This form of mimicry provides a mutual benefit because it reinforces the avoidance behavior of predators who learn to associate the specific appearance of these unpalatable species with a negative experience, such as an unpleasant taste or food poisoning. As a result, both species benefit from a reduced risk of predation.

In this context, both species benefit from the shared warning coloration or other traits that signal their unpalatability, leading to a more efficient learning process for potential predators. This is distinct from other forms of mimicry, such as Batesian mimicry, where a palatable species mimics an unpalatable one, or aggressive mimicry, where a predator mimics a harmless model to lure prey. Understanding the concept of Mullerian mimicry helps in appreciating the evolutionary strategies that promote survival among species in a shared ecological environment.
