Brazilian Scientists Discover World?s First Venomous Frogs

Scientists in Brazil have discovered what they say are the world’s first venomous frogs. When Brazilian biologist, Carlos Jared and his team of herpetologists discovered the frog in a jungle in Brazil’s Goytacazes National Forest, Jared picked the frog up for further examination and when he did so, the frog raked its upper lip across Jared’s hand and injected a venom that caused him severe pain for the next five hours.
