A study on the distribution of recent benthic ostracoda in surface sediment was carried out along the Pahang River Estuary, in the east coast of Peninsular Malaysia (South China Sea). A total of 30 sediment samples were taken from sampling stations between latitude 3°12’ and 3°47’N and longitude 103°24’ and 103°43’E. Result showed that a total of 5,033 specimens of ostracoda belonging to 18 families, 41 genera and 76 species were identified. The dominant species was Phlyctenophora orientalis with 582 specimens obtained, then followed by Pistocythereis bradyi (386 specimens) and Lankacythere coralloides (332 specimens). Trachyleberididae was the dominant family with 1,601 specimens and had the most variety of species with 18 species. The species diversity was from 3 to 35 species. The abundance of ostracoda was from 5 to 2,248 specimens. The species diversity index, H' was in the range of
1.06 to 3.10. The abundance and diversity of ostracoda were mostly related to the type of the sediment.
