CORE DEFINITION

Müllerian mimicry is a type of biological mimicry in which two or more well-defended species, often foul-tasting and sharing common predators, converge in appearance to mimic each other's honest warning signals. This convergence of appearance achieves the following benefit to species that undergo it: predators need only experience a single unpleasant encounter with any member of a set of Müllerian mimics to learn to avoid the entire set, reducing the cost of education for each species.

Anchor fast decisions

Two harmful species evolve the same warning coloration, so that a predator that learns from one encounter will avoid both, sharing the 'education cost' and benefiting both. This is an alliance of honest signals, distinct from the deception of Batesian mimicry.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

First, identify opportunities to 'co-educate the market' with competitors. Second, adopt a unified interface or appearance to share the education cost. Third, use honest signals to grow the category rather than copy each other. Fourth, be wary of confusing this with Batesian mimicry (disguise).
