This is one of only a small variety of submerged aquatic plants in Victoria. Submerged aquatic plants provide a valuable substrate or aquatic wildlife, from food for Black Swans to being a surface on which biofilm can form. Biofilms are made up of fungus, bacteria and algae which coat the submerged surfaces. These biofilms are biologically rich substances which support many other forms of life. Growling Grass Frogs (Litoria raniformis) make use of submerged aquatic plants like Curly Pondweed as a support where they can bask beyond the shade of dense semi-aquatic plants of the water's edge.
