This short audio documentary is about a frog called Toughie. He was a Rabbs' Fringe-Limbed Tree frog and was native to Panama. Toughie was the last frog of his species: an endling. In this non-narrated piece, amphibian biologist Mark Mandica tells the story of Toughie's rescue, his time taking care of an animal that was going extinct, and what it's like witnessing the extinction of so many creatures that he loves.
