    Abstract
    Extensive studies on occurrence, distribution and species composition of luminous bacteria in the Arabian Sea were carried out from various habitats. Luminous bacterial population was by far the highest in the environs of the Arabian Sea. Their distribution pattern was of freeliving nature in coastal, lagoon and upper 200 m of oceanic regions. Their numbers were low in the oligotrophic equatorial waters. Vibrio harveyi, V. fischeri, Photobacterium leiognathi and P. phosphoreum were the luminous species found to occupy various niches. V. harveyi showed a greater ecological versatality, V. fischeri, a remarkable ecological adaptation and P. leiognathi occurred mostly as light organ symbiont in leiognathid fishes. P. phosphoreum was recorded from the water column with temperatures lower than 25 degrees C. Bacterial luminescence in all the seawater samples was very low indicating energy conservation mechanism in free living luminous procaryotes. In contrast, a 10000 fold higher bacterial luminescence was observed from all the examined zooplankton samples implying an abundance of surface associated luminous microflora and a continuous luciferase synthesis
