Posidonia is a genus of flowering plants. It contains nine species of marine plants [3] ("seagrass"), found in the seas of the Mediterranean and around the south coast of Australia.

Posidonia oceanica, commonly known as Neptune grass or Mediterranean tapeweed, is a seagrass species that is endemic to the Mediterranean Sea. [2] It forms large underwater meadows that are an important part of the ecosystem.

The species Posidonia oceanica is endemic to the Mediterranean Sea. It forms extensive underwater meadows that grow on rocks and sandy bottoms in clean water from the surface to over 40 meter depth. The rest of the Posidonia species (of which there are 7-8) are found in Australian waters, which illustrates the antiquity of the genus.

What is the Posidoniaceae Family? The Posidoniaceae family consists mainly of seagrasses that thrive in shallow marine environments. These plants are characterized by their long, ribbon-like leaves and their ability to grow in sandy or muddy substrates along coastlines.

Although it lives exclusively in the sea, Posidonia oceanica is a real plant with roots, flowers, fruits, and long ribbon-like leaves. Its history began 70 to 100 million years ago when flowering terrestrial ancestors colonized the ocean floor, creating a unique marine ecosystem.

2017年10月25日 · Posidonia oceanica has been called “the lungs of the Mediterranean” because it is one of the most important sources of oxygen provided to coastal waters.

POSIDONIA OCEANICA IS A UNIQUE MARINE PLANT FOUND IN THE MEDITERRANEAN SEA. It forms extensive meadows around the Balearic Islands, known as underwater forests, capable of harboring a high biodiversity of species.

Posidonia oceanica is a species of seagrass endemic to the Mediterranean Sea. Forming underwater meadows, it creates essential living habitats for thousands of marine species. Many fish species depend on these habitats for their regular living and feeding grounds.

Posidonia spp. response and recovery following periods of reduced light, burial and sedimentation is species-specific and dependent on many additional factors such as the extent and duration of light reduction, as well as the depth of burial (Table 2).

• Posidonia sp.: tidal deposits of inflorescence and leaf material. • Posidonia sp.: opened fruits, showing seeds germinating prior to dehiscence . We advise against extracting comparative information from the descriptions.
