Mangrove palm - sea grass had a different zooplankton structure compared with transition area and coral reef with a lower number of species and similarity index about 40 . The average density of zooplankton in study areas in dry season 24 559 24 700 were 4 times higher than in rainy season 6 124 and dominated by copepoda. The euryhaline cladocera Bosmina longirostris freshwater cladocera Ceriodaphnia rigaudi and freshwater copepoda Microcyclops varicans were dominant in mangrove palm - seagrass ecosystem. Meanwhile in coral reef ecosystem the small copepods genus Oncaea Oithona and Tunicata were dominant. Biodiversity indices were low in mangrove - palm and increase from transition area to coral reef ecosystem. Keywords Biodiversity zooplankton Cu Lao Cham copepod.
