Abstract

The present paper describes in detail the taxonomy, morphology and ecology of two dinoflagellate genera, Protoperidinium and Podolampas, from the North Arabian Sea bordering Pakistan's coastline. Diagnostic descriptions and illustrations based on light and scanning microscopic observation of the organisms are provided for all 13 species of the two genera form the study area. The spatial distribution revealed that most species were rare except Podolampas bipes and Protoperidinium depressum which were common and the number of species was higher on the Indus delta shelf than on the Balochistan shelf. The number of species recorded during the monsoon transition period was higher than the northeast monsoon season.
