Incredibly Rare Irrawaddy Dolphins Found In Indonesian Waters (10 Pics)

Back in 2012, and for the first time, Irrawaddy dolphins were spotted in West Kalimantan, a part of Indonesian Borneo which is well known for its rich wildlife and dense tropical forests. Also known as orcaella brevirostris, the rare dolphins were found during a study in by WWF-Indonesia and the Regional Office for Marine, Coastal & Resources Management Pontianak (BPSPL).

Conservation challenges: "The results of this study indicate the importance of protecting the dolphins' habitat, from the origins of the rivers in the Heart of Borneo, to the lower rivers of the island, including waterways of Batu Ampar mangroves and nypah forests, the narrow straits and the coastal areas of Kubu Raya, West Kalimantan," Albertus Tjiu said.
