There are about 80 species of pondweeds in the world. They occur in a variety of aquatic habitats. Some pondweeds are totally submersed, others have floating leaves. Pondweeds may be relatively large plants, such as Potamogeton illinoensis, and some are small, such as Potamogeton diversifolius. Some have relatively large leaves, such as Potamogeton nodosus, and others have very narrow leaves, such as Potamogeton pusillus and Potamogeton pectinatus. Pondweeds are very important as wildlife food.
