Surf Diatoms of the Lagos Lagoon Beach, Nigeria

Abstract

Investigations into the dry season surf diatoms of the Lagos lagoon along the University of Lagos beach were carried out for six months (Dec. 1989 – May 1990). Forty-two diatom taxa belonging to 23 genera were recorded. The diatoms recorded, showed euryhaline tendencies. On the whole the more frequent species were Navicula expansa, Achanthes coaractata, Cymbella minuta, Nitzschia irresoluta, Nitzschia closterium, Gyrosigma tenuissimum, Amphora ovalis and Hantzschia amphioxys. The importance of these diatom to the shore–line sandy habitat fauna was highlighted.
