Twelve sediment samples were collected from the sampling area around Pulau Bidong.
In situ parameters that have been taken were depth, salinity, temperature and
dissolved oxygen. The sediment samples were analyzed in the laboratory for
foraminiferal and grain size analyses. 300 individuals of optimally preserved
foraminiferal specimens have been picked under the dissecting microscope, sorted
and identified. The foraminiferal data was analyzed in PAST software version 3.19.
Grain size distribution have been done by using mechanical sieve shaker and was
analyzed by using the software Gradistat version 15. Overall, majority of the dominant
species preferred epifaunal life position except for two species which showed no
preferences to either infaunal or epifaunal life position; Peneroplis pertusus and
Quinqueloculina rugosa. Environmental factors such as depth and grain size
parameters (mean, skewness, sorting and proportion of gravel) were the major factors
that influenced the foraminiferal distribution in Pulau Bidong.
