Pictures of poison frogs are a popular form of home decor. Tiny size, bright colors, super deadly, they've got it all. But how exactly do poison frogs avoid poisoning themselves?

And we speak with Sandra Goutte, a herpetologists who studies frog ears, how they work, and whether one tiny, adorable pumpkin toadlet can hear itself talk.
