 Rabbs' Fringe-limbed Treefrog

The legacy of the Rabbs’ fringe-limbed treefrog 

Scientists at Zoo Atlanta and the Atlanta Botanical Garden led the effort to discover and formally name the Rabbs’ fringe-limbed treefrog, which once inhabited mountain slopes above the town of El Valle de Anton in Central Panama. 

The only known population of the species was drastically reduced immediately upon the arrival of the fungal pathogen Batrachochytrium dendrobatidis into the region in 2006. One individual was heard calling in 2007, and none of these frogs have been heard or observed since. The species is now considered extinct in the wild. 

One of only two known Rabbs’ fringe-limbed tree frogs on Earth, died at Zoo Atlanta in 2012. The other, also a male, resides at the Atlanta Botanical Garden. 

The legacy of the Rabbs’ fringe-limbed treefrog serves to remind us that even as new species are discovered on a very regular basis, some go extinct before scientists ever have a chance to learn more about their natural histories, behaviors or roles in their ecosystems. Support for conservation programs at Zoo Atlanta help us to ensure that other species – in the Rabbs’ fringe-limbed treefrog’s native Central America and in many other wild places around the world – don’t vanish forever before we have a chance to understand and appreciate them.
