What feature distinguishes the coontail plant?

The feature that distinguishes the coontail plant is its unique leaf structure. Coontail, also known as Ceratophyllum demersum, has whorled leaves that are finely divided and appear fan-shaped, often with small, tooth-like projections along the edges. This leaf morphology is a key identifier of the coontail plant and differentiates it from other aquatic plants.

The leaves are typically arranged in whorls around the stem, which contributes to the plant's distinctive appearance in water bodies. Unlike many other aquatic plants, coontail does not have true roots but is anchored in the substrate by its vegetative growth. Understanding the leaf characteristics of coontail is important for proper identification and management in aquatic ecosystems.
