Irrawaddy Dolphin Orcaella brevirostris Estimated numbers remaining in the wild: 300-327 Found in the Mekong River, Mahakam River (Indonesia), Irrawaddy River (Myanmar) and Malampaya Sound (Philippines) The Irrawaddy Dolphins are part of the freshwater dolphin family found in the shallow rivers and coastal areas of South and Southeast Asia. Unlike the typical porpoises with long snout, they have high rounded forehead with a short snout and have 12-19 teeth on each side of their jaws. These shy dark grey dolphins with a distinctive pale underside can grow up to 9 feet and weigh up to 198 pounds. The Irrawaddy Dolphin population is small and is scattered over wide areas. Unfortunately, its numbers in Southeast Asia have been dwindling due to incidental death caused by fishing and human activities, loss of habitat as a result of deforestation, mining and dam construction.
