Frogs and toads are some of the most confusing amphibians to classify. While some of their physical attributes are easy to tell apart, if we take a deeper look at these animals we find it’s not quite that simple. From poisonous skin and bulging eyes to their amazing life cycles, these creatures are as interesting to study as they are difficult to categorize. Once we break down the difference between “true” frogs and “true” toads, it’s easy to see why so many have trouble telling the two creatures apart!
