The Evolutionary Ecology of Aposematism and Mimicry in Toxic Amphibians

Quick fact

In some poison dart frog species, individuals from different populations can have completely different color patterns, each advertising the same toxicity, while harmless species often evolve to resemble them—a phenomenon known as Batesian mimicry that can fool predators into avoiding a perfectly edible meal.

Why this is interesting

Imagine a tiny frog so brilliantly colored that it stands out against the leafy forest floor—yet predators rarely eat it. How can being so conspicuous be a survival strategy?
