This study documented gonadal development and gametogenic process for the Lymnaea acuminata snail from Aurangabad (M.S.), which is located in North 19°53'47"- East 75°23'54" on the World map. Random collection of different sized group of the snail was made as follows : A) 3±1 mm shell length, B) 8±1 mm shell length, C) 11±1 mm shell length, D) 14±1 mm shell length and E) 20±1 mm shell length. The gonads in the form of hepatopancreas - gonadal complex were studied histologically. Microscopic observations were revealing that during growth phase of these snails start first with male phase and followed by maturation of female phase. This type of gonadal maturation and process of gametogenesis in the snail Lymnaea acuminata is referred as protandric hermaphroditism. These finding are important and throws light in the field of reproductive physiology of the freshwater snail L.acuminata.
