Zooplankton is important as a major source of fish food. This study dealt with the spatial and temporal distribution of zooplankton in Al Salwa beach, Jazan sandy shore, the muddy shore of Baish coast, and the sandy coasts of Al-Shuqiq, Al-Moassum, and Farasan. Water properties were determined, including water temperature, pH, conductivity, dissolved oxygen, and total dissolved solids. Species richness, population abundance, relative abundance, and Shannon-Weiner diversity index (H^-) were studied. 11 species were identified; ciliates, free-living nematodes, calanoid copepod, nauplius larva, gnathostomulida, water mite, Meliola, medusa, Polychaeta, zoaea larva, and Tardigrada. The highest species abundance was for ciliates on Al-Shuqiq sandy shore, while the lowest was for water mites on Jazan sandy shore coast. Shannon-Weiner diversity index (H) was 1.05 on the sandy coast of the Jazan region and 0.39 on the mangrove coast of Baish. The regression analysis between water criteria and the zooplankton abundance showed a significant relationship of water temperature (P<0.05) with ciliates. Data were discussed to highlight the factors affecting zooplankton distribution in marine habitats.
