sorry I cant tell from the photo - nearest would be a umbrella/moon jelly (Aquorea eurhodina) but it's usually easy to see the 4 underside lobes.

This sighting of a freshwater species is misplaced under 'Marine invertebrates'. It should be under 'Other arthropods: Crustaceans: Other crustaceans' (Other Crustaceans).
