Abstract :

A freshwater mollusca belonging to Gastropoda Physa acuta which was reported earlier only two localities from India. The present study is reporting this species as a new distributional record from state of Andhra Pradesh for the first time. Morphomitric analysis of the shell shows that the significant correlation between total length and width (r = 0.965). It is also been observed that the numerical abundance of population in eutrophic water bodies, could be used as biological indicator for further bio-monitoring of the water bodies and conservation of faunal diversity.
