Irrawaddy dolphins can be seen in three major rivers in Southeast Asia: the Ayeyarwady (Myanmar), the Mahakam (Indonesian Borneo) and the Mekong. In Myanmar, the dolphin is known for its close relations with local fishers as they often help to drive shoals of fish towards fishing nets in exchange for the fishers throwing them fish.
At present, these gentle and good-natured creatures are facing a number of threats to their survival and habitats. These threats range from contaminated water from industrial and agricultural activities, run-off from gold and other mining, entanglement in fishing gear, and changes in habitat due to coastal construction or river traffic. More recently, dolphins are also being threatened by the increased use of electric fishing devices and the over-fishing of many rivers .
