Whose studies helped explain how poison dart frogs get their toxins?
Quick Answer
German herpetologist T. P. S. C. de Rooij and later researchers showed that many poison dart frogs do not make their own toxins from scratch. They often obtain poisonous alkaloids from their insect diet.
The Full Story
Modern research on poison dart frogs is associated with herpetologists including T. P. S. C. de Rooij and later chemists and biologists who studied their skin alkaloids. These brightly colored frogs, found in Central and South America, often sequester toxins from ants, mites, and other small prey. The frogs then store the chemicals in their skin as a defense against predators. The famous golden poison frog, Phyllobates terribilis, is among the most toxic vertebrates known.
