On receipt of this information, Dr Kamal Ranatunga of the University of Sri Jayewardenepura and Sumedha Abesinghe of Aquariums - National Zoological Gardens rushed to Polonnaruwa to investigate the mystery. They collected samples and carried out an investigation.
On completion of the investigation Dr. Ranatunga identified the creature as a rare freshwater jellyfish exhibiting a Medusa stage in its life cycle.
The Freshwater Jelly Fish (Craspedacusta sowerbyi) is usually found in calm, clean bodies of water throughout the world. They are found in US lakes and rivers as well as in China.
This, however, is the first reported sighting of the creatures in Sri Lanka.
