The study was conducted at northwestern Sarawak waters with depth between 43 m<br />

to 71 m. Seven surface samples were collected and 200 individuals of benthic<br />

foraminifera were picked from each sample. Eleven genera were identified from the<br />

study site. Heterolepa spp., Textularia spp., Quinqueloculina spp., Operculina spp. and<br />

Pseudorotalia spp. are common genus found in the samples. The cluster analysis form<br />

cluster (a), dominated by Pseudorotalia spp. and cluster (b) dominated by Heterolepa<br />

spp. The highest index value of diversity is 3.23 at depth 67.76 m and the lowest value<br />

is 1.53 at depth 45.54 m and 68.45 m. From the study, depth is not the main factor<br />

that influences the diversity of benthic foraminifera in northwestern Sarawak waters.<br />
