Bahuda estuary is a small estuary situated in the Ganjam district at the extreme south of Odisha. The estuary covers an area of 15 km2 within average depth of 2.6 meter. An initial study was undertaken by me to explore the malacofauna diversity of this estuary. The duration of the study was 6 months. Studies were conducted by hand picking method, digging the substratum, collection by net & photographic capture. The study yielded 44 molluscan species belonging to 2 Classes, 9 Orders, 26 families and 35 genera. It was concluded Bahuda is rich in Gastropods and Bivalvia. 26 species of Gastropods and 18 species of Bivalvia were collected. Neogastropoda &Veneroida were reported to be the most spacious order of Gastropoda and Bivalvia respectively. Oliva oliva was the most abundant molluscan species present in the estuary. 18 new species were added to the previous checklist of mollusc diversity of Bahuda estuary.
