Abstract
The green Noctiluca scintillans (Macartney) Kofoid & Swezy 1921 and its green water discolouration are reported here for the first time from the coastal waters of Northwest Arabian Sea bordering Pakistan. The symbiont present inside was recognized as Pedinomonas noctilucae (Subrahmanyan) Sweeney. Patches of green water were observed occasionally in the highly polluted coastal areas with dense mangrove vegetation during five-year period. The concentration of the organism was as high as 2.4 million cells per liter imparting green coloration to the seawater, which lasted for about a week.
