Macrobenthic diversity in horseshoe crab nesting ground-Balok Station, Pahang, Malaysia

A complete year data on the diversity and distribution of major macrobenthic community along the horseshoe crab nesting ground in Balok station was studied. Here we present the monthly and seasonal variation in the macrobenthic community along the balok station during full moon days. Monthly variati...
