All the food chains in any ecosystem starts with the plants. They perform photosynthesis and transfer the energy to all other organisms. To understand the diversity and distribution pattern of some selected algal flora along the coastal sites of the Red Sea, this preliminary research was conducted in November-2019. Three common quantitative parameters for diversity studies viz. frequency, density and abundance were determined for the five selected algal species namely Padina, Sargassum, Dictyota, Polysiphonia and Ulva. The results of this research showed different patterns of occurrence and distribution of algal flora along the selected coastal sites of the Red Sea at Haql. The overall results on frequency, density and abundance reveals that among all the algal species Sargassum sp. was recognized as highly dominant species whereas Ulva sp. as rare species at the six different study sites at Haql.
