Posidonia oceanica, (commonly known as Neptune grass, or Mediterranean tapeweed,) is a seagrass, species that is endemic, to the Mediterranean Sea,. It forms large underwater meadows that are an important part of the ecosystem. The fruit is free floating and known in Italy as "the olive of the sea" (l'oliva di mare). Balls of fibrous material from its foliage, known as egagropili, wash up to nearby shorelines.
Location: Ibiza, Balearic Islands, Spain
