Herpetological Highlights

Toads are wonderful creatures, and their exceptional adaptability makes them superb invaders when transported to new lands by humans. Unfortunately, this can be bad news for the creatures already present –see Cane Toads in Australia. We check in on the progress of Asian Common Toads in Madagascar this episode.
