Yes …, common plant for Physiology experiments.
In our childhood days we used to keep this plant in the fish tank.
Good specimen to study the hydrophytic group of plants, along with the Typha species…
Hydrilla is a noxious water weed here in much of the US. I don’t know its status in India, but I suspect it could be very problematic there as well. http://www.protectyourwaters.net/hitchhikers/plants_hydrilla.php
Hydrilla here grows only during the months of July August and September. After this water dries up and wheat is sown so till now no great problem
It is really problematic in Dal Lake of Kashmir, where the Government spends huge amounts every year for de-weeding of the lake

In Lotus Pond, Hyderabad, AP on 9/5/09.
It looks like the dreaded Hydrilla that chokes our lakes here. The cure is to release Tilapia into the water to eat it.
It is Ceratophyllum submersium.
IT is tough to identify from this photo but i think it may be species of Hydrilla from Hydrocarytaceae family
I found a few links for Ceratophyllum submersum: http://commons.wikimedia.org/wiki/Category:Ceratophyllum_submersum & http://www.biopix.com/Species.asp?Searchtext=Ceratophyllum%20submersum&Category=Planter (a few pix).
However, at first glance these appear to be a bit different to a layman like me (though I may be wrong).
It certainly appears close to Hydrilla verticillata as per links: http://www.ncwater.org/Education_and_Technical_Assistance/Aquatic_Weed_Control/weeds.php & http://www.apms.org/plants/hydrilla.htm
It is Hydrilla species. Ceratophyllum should have one or twice forked leaves, and much slender leaf segments
ID of the waterweed Photographed in Kanha: I photographed this In Kanha National Park Last Week.
A swamp Deer is eating this waterweed in a pool.
May I request for help in ID of this waterweed.
– Yes it looks like Hydrilla verticillata
