In What Makes Poison Dart Frogs Toxic?, evolutionary biologist Ben Garrod discusses how poison dart frogs produce their toxins. Learn how these frogs derive their toxicity from alkaloids found in their diet, how they use their poison for defense, and why scientists are studying these toxins for potential medical uses. This video is excerpted from Secrets of Skin, a documentary series exploring the natural history of the body’s largest organ.
In How Amphibians Have Mastered Both Land and Water, evolutionary biologist Ben Garrod explains how frogs’ skin has adapted to help them survive in different environments. Specifically, frogs' skin helps them breathe both on land and in water. Learn how frogs can absorb oxygen through their skin, which is essential for their survival, especially for species like the Titicaca frog that never needs to surface to breathe. See how the structure of a frog's skin serves other functions, such as keeping out harmful microbes, and how different species of frogs have unique adaptations that help them thrive in their habitats.
