Abstract
A preliminary survey was made of over 500 kilometers of the southern east coast of India starting from Nagore in the
Bay of Bengal (19-degrees-50'N and 79-degrees-50'E) and ending at Cape Comorin in the Indian Ocean (8-degrees5'N and 77-degrees-33'E) including Palk Strait, Palk Bay and the Gulf of Mannar. The survey of cyanobacteria in each
region included different areas viz. open sea, stagnant sea water ponds and puddles, backwaters and salt pans. During
the survey the nature of the sea shores in all the regions were examined and representative samples of sea water were
taken from different regions for chemical analysis. The Gulf of Manner region, with vast areas of rocky shores and
nutrient rich water, showed the maximum cyanobacterial diversity. A total of 163 species from 48 genera belonging to
14 families of cyanobacteria were recorded in the survey. Thirty two species from 13 genera, all of which were nonheterocystous, were considered versatile, since they occurred in all areas in different regions. Amongst these,
Phormidium tenue was the most versatile species because it occurred not only in all areas but also in all regions of the
survey. An important observation revealing the remarkable adaptability of cyanobacteria was that 75 of the species
recorded during the survey had been originally reported from freshwater sources by earlier workers. Another interesting
observation was the total absence of heterocystous forms in hypersaline environments (salt pans).
