Marine centric diatoms comprising of 101 species and 30 genera were recorded from highly polluted lower harbor , Karachi chaetoceros and rhizosolenia were the most diverse genera . the temporal and spatial distributionsof species were irregular and species diversity hih, which may be the result of extremely unstable environmental conditions in the harbor. The species composition was also significantly different from that of the shelf.
