Which type of mimicry involves a harmless species mimicking a harmful one?

Batesian mimicry is a form of mimicry where a harmless species evolves to imitate the appearance of a harmful or unpalatable species. This adaptation serves as a survival strategy because potential predators may avoid the harmless mimic due to its resemblance to the harmful species, believing it to possess the same defenses. The mimic gains protection by virtue of its similarity to the harmful model, while the model benefits from a reduction in predation due to its dangerous reputation.

In contrast, Mullerian mimicry involves two or more unpalatable or harmful species that evolve to resemble each other, reinforcing the avoidance behavior in predators. Aposematism refers to warning coloration, where a species displays bright, obvious coloration to signal danger, and cryptic coloration is a strategy of camouflage, where an organism blends into its environment to avoid detection.
