Pengamatan Pesut Mahakam (Orcaella brevirostris) di sepanjang perairan sungai Mahakam (Dolphin Observation along the river of Mahakam)
Author(s): Chandra Boer, Dan Iwan Suyatna
Abstract: The population and distribution of dolphins along the Mahakam River extends very far upstream and into the river’s tributaries. The influence of ocean tides and flooding provide opportunities for dolphins in Mahakam to search for food in these distant parts of the river. Often these dolphins become trapped and cannot return to the areas they came from and may develop into sub-populations.
