Vallisneria

[Ed Pirog]

I am presently doing a study on the Red eared Slider (Trachemys s. elegans). A
reference cited that one of it's food sources is Eel grass (Vallisneria). Can
someone possibly give me a reference, or references that might be able to fill
in the blanks as to what else uses this plant as a food source, propagation,
and general natural history of the plant. Any input would be greatly appreciated.
