Since 2009, staff at Wildlife Conservation Society's Bronx Zoo have been working behind the scenes to save the Eastern hellbender. Now, this elusive salamander can be seen in a new exhibit in the zoo's historic Reptile House beginning April 26, 2017. The Eastern hellbender is a large species of salamander native to freshwater rivers and streams in Eastern North America. New York State lists the hellbender as a species of Special Concern. Populations are declining due to several factors including over chytrid fungus, water pollution, and habitat destruction. Photo by Julie Larsen Maher/WCS/UPI
