    • Abstract


      The SpongillidCorvospongilla lapidosa (Annandale 1908) (Porifera: Spongillidae) is reported for the first time from the Manjira reservoir in Andhra Pradesh. Its sausage shaped spicules have adaptive value to thrive in low silica environments. The species is tolerant to high turbidity. High calcium and bicarbonate may be unfavourable and the sponge ha? not been found either on molluscan shells or on aquatic vegetation. It can thrive in waters more than 4 m deep. The range and mean values of twenty-seven physico-chemical parameters of the habitat ofC. lapidosa are given as the base data for the species ecology.
