Macroalgae
Definition
Filamentous or thalloid algae visible to the naked eye, such as Spirogyra, Cladophora, Enteromorpha, and Chaetophora. They colonise sheltered margins, shallow water, and submerged surfaces. Their presence as fragments on clothing or vehicles indicates contact with vegetated shallow water.
