PILA

• Pila globosa is one of the largest freshwater molluscs, found in freshwater ponds, pools, tanks, lakes, marshes, rice fields and sometimes even in streams and rivers.

• They occur in those areas where there is a large amount of aquatic vegetation like Vallisneria, Pistia, for food. They are amphibious, being adapted for life in water and on land.

• The movement of the animal is like the gliding movement of a planarian.

• It can overcome long periods of drought in a dormant condition and buried in the mud; this period of inactivity is called aestivation or summer sleep.
