The picture below showed the size of the snail compared to the smaller Bladder Snail (Physa acuta). The other picture showed egg masses that might belong to this snail.

This fresh water snail is supposed to be common in some South-East Asian countries. From the number of reports seen [1-3], this snail appeared to be very common in India and a handy experimental subject. It is the host of some parasites that may infect animals and humans [1, 4]. Despite the many reports, mainly on the invasiveness, parasitic host and control of this snail, pictures of the life snail are rare in the Internet.
