Abstract:
The island of Borneo includes the Malaysian states of Sabah and Sarawak, the Indonesian state of Kalimantan, and the islamic sultanate of Negara Brunei Darussalam. Although there has been little work done on marine mammals in this area since the 1950’s, a number of species have been recorded from the island, mostly from strandings and opportunistic sightings. Of these, 16 have been confirmed based on reliable records. Three brief research visits to Sabah and Sarawak have shown that the poorly-known Irrawaddy dolphin is common in several estuaries along the north coast of Borneo. Preliminary work found an average group size of 4.4 ± 2.19 S.D. (n=28). Seven individuals were photo-identified. In addition, evidence of coastal populations of Indo-Pacific hump-backed dolphins, finless porpoises, and dugongs was gathered. More work on all these species is planned to assess populations, identify threats, and ensure the animals are effectively conserved.
