The Ecological Significance of Toxin Sequestration in Poison Dart Frogs

Quick fact

In captivity, poison dart frogs lose their toxicity because their wild diet—particularly certain ants, mites, and beetles—supplies the alkaloid compounds they sequester, while frogs raised on fruit flies remain non-toxic.

Why this is interesting

Imagine a frog that isn't born poisonous but becomes so by eating its lunch. How does a diet of tiny ants turn a harmless amphibian into one of the most toxic animals on Earth?
