In the recent years, underwater visual survey is becoming as a powerful investigation technique, especially in focus to deep-sea study. In this paper, we report seabed investigation made with an easy-to-operate indigenously built lost cost underwater camera (4K resolution) system depth rated ~2000m along with 6000 lumens LED light source. We have attempted to study the cold seep sites located in Krishna-Godavari basin, Bay of Bengal. The study was carried out at ~1750 m water depth. During the expedition, we could observe deep-sea bed characterised by shell bed and burrows, wide range of water habitats such as demersal fishes, shrimps, sea urchins and echinoderms etc. We could observe, a significant cold seep characteristic Siboglinidae polychaete (Sclerolinum sp.). Sclerolinum is a mouthless and gutless polychaete and harbours sulfur-oxidising bacteria. This study offers an opportunity to study wide range of underwater environments.
