Growth studies on <i>Clypeomorus clypeomorus</i> Jousseaume (Gastropoda: Cerithiidae) from the Visakhapatnam Coast

12-15Growth rate of C. clypeomorus has been measured employing analysis of population sampling and calculation of absolute growth rate. Height and age relationships of the snail are studied. Results show clear seasonal variation in growth rate of the snail, maximum shell height of 18 mm and survival period of 1 yr. It attains sexual maturity at shell height of 11-12 mm and breeding is continuous. The small size and relatively short life span may be due to early attainment of maturity and continuous reproductive activity
