Description: Posidonia sp. is commonly known as Neptune Grass, is a seagrass species that is endemic to the Mediterranean Sea. It forms large underwater meadows that are an important part of the ecosystem. It is found at depths from 1–35m, according to water clarity. The leaves are ribbon-like, appearing in tufts of 6 or 7, and up to 1.5m (4.9ft) long. Average leaf width is around 10mm (0.39in). The leaves are bright green, perhaps turning brown with age, and have 13 to 17 parallel veins. The leaf terminus is rounded or sometimes absent because of damage. Leaves are arranged in groups, with older leaves on the outside, longer and differing in form from the younger leaves they surround.
