To gather clues about their diet and environment, researchers capture tropical frogs and flush their stomachs to make them vomit their lunch, then release them unscathed back into the wild. University of Rochester myrmecologist Christian Rabeling and colleagues used this method on tropical frogs. The frog is neon-orange and poisonous. It's believed that their toxic secretions are thanks to a steady diet of ants, whose own diets contain alkaloids from plants. These alkaloids play a part in how poison dart frogs convert their own snacks into deadly defense mechanisms against larger predators.
