Answer:
Müllerian mimicry
Explanation:
Mullerian mimicry occurs when two or more unpalatable species adopt a single warning coloring pattern. This way they can avoid a greater number of natural enemies.
In more detail, Müllerian mimicry occurs when two non-palatable species (ie, which do not taste pleasant to predators) or which have other defense mechanisms resemble each other. In this kind of mimicry, what is observed is that the learning of predators benefits from the increase of mimetic species and also from the increase of the other species, since both cases reinforce the association between their physical pattern and their defense mechanism. .
