Maryland Zoo joins effort to rescue rare Bolivian river dolphins

Veterinarians from The Maryland Zoo and the Saint Louis Zoo traveled nearly 4,000 miles to rescue dolphins in central Bolivia, where a group of approximately 15 endangered Bolivian river dolphins (Inia geoffrensis boliviensis) were trapped in a lake.  The dolphins, known in Bolivia as bufeos, were isolated in the lake surrounded by dense forest and expansive soybean fields, and had become cut off from the main river over the past several years due to run-off from environmental changes in the area.
