Short description

Biology     Glossary (e.g. epibenthic)

Edible. Used as medicine and source of vitamins E, A, and B1 (Ref. 80758). Also has the potential use as animal feeds in the form of ground meal (Ref. 26875). Grows in intertidal areas exposed to air during low tides, in shallow water near shores, or attached to other seaweed species such as Sargassum (Ref. 80758). Often detached and free floating at midtide (Ref. 801). Abundantly found in areas with varying salinity and develops rapidly in nutrient-rich waters, thus, common in polluted areas (Ref. 26875).
