The Story of 'Toughie': How the last known gliding tree frog vanished

The last known Rabbs' fringe-limbed tree frog, named Toughie, died in 2016, marking the species' likely extinction. Researchers collected a small group of the frogs from Panama in 2005 to save them from a spreading fungal disease. The species was known for its ability to glide between trees and its rare parental care behaviors. Captive breeding programs were unsuccessful, leaving Toughie as the last surviving individual after 2012.
