Common name: Sea Lettuce Family

The Ulvaceae family, commonly known as the Sea Lettuce Family, includes various species of green macroalgae found in marine environments worldwide. Members of this family are characterized by their bright green color, sheet-like or filamentous thallus, and simple cellular organization. They are important primary producers and serve as a food source for a variety of marine organisms. In reef aquariums, species like Ulva lactuca can be cultivated as a nutrient export mechanism, helping to control nitrates and phosphates, and as a natural food source for herbivorous fish and invertebrates.
