A study on substrate dependence distribution of benthic foraminifera was conducted
in Pulau Bidong, Malaysia. Twelve surface sediment samples were collected from four
transects. There were 14 dominant species of foraminifera that have been identified
which include Amphistegina lessonii, Operculina ammonoides, Amphistegina papillosa,
Peneroplis pertusus, Textularia foliacea, Elphidium advenum, Pseudorotalia angusta,
Nummulites venosus, Quinqueloculina spp. and Pyrgo sarsi. Canonical
Correspondence Analysis (CCA) classified the substrate types into three groups which
is coarse sand, very coarse sand and medium sand. Operculina ammonoides shows
abundant distribution in coarse sand as proved by the highest percentage (69% of the
samples), abundant species in very coarse sand is verified by 64% of the samples by
Peneroplis pertusus and Textularia foliacea represent abundant distribution in medium
sand with 47% of the samples. Environmental factors such as salinity, dissolved
oxygen and temperature not a strong factor that affecting the distribution of benthic
foraminifera in Pulau Bidong.
