Enteromorpha is a genus of green algae commonly found in marine environments, particularly in intertidal zones. These algae are characterized by their thin, filamentous structure and bright green color. They thrive in nutrient-rich waters and can often be seen growing on rocks, shells, and other surfaces. This genus plays a significant role in coastal ecosystems by providing habitat and food for various marine organisms. Enteromorpha can also indicate water quality, as its growth is influenced by nutrient levels, particularly nitrogen and phosphorus, often linked to pollution from human activities.
