Toughie, the last Rabbs’ fringe-limbed tree frog, passed away at the Atlanta Botanical Garden on September 28, 2016. He was estimated to be 12 years old. Missions led by the Atlanta Botanical Garden and Zoo Atlanta first collected Toughie in 2005. They tried to save frogs like him from chytrid, a deadly fungus in Central Panama. After Toughie died, scientists cryogenically froze him to preserve his body. They hope to use his body for future research.
