Distribution of recent ostracoda in offshore sediment around Pulau Besar, Johor

The study on distribution of ostracods in offshore sediment was made around Pulau Besar, Johor. A total of 11 stations were chooser. A total of 47 species, both living and dead belonging to 37 genera and 18 families were collected and had been identified. A total of 1063 dead specimens and 932 livin...
