It is an angiosperm plant, with flowers and fruits (it is not an algae).
It lives from 0 to 45 meters deep. We can find it between the superficial level up to 45 meters, although the most common limits are 30 meters throughout the Balearic coast. There are other seagrasses in other places like Australia. Posidonia australis
Posidonia generates oxygen and helps keep the waters of the Balearic Islands so transparent and clear. Posidonia has been called “the lungs of the Mediterranean”.
"Carbon sequestration of one hectare of Posidonia from Formentera is equivalent to 15 hectares of Amazon rainforest."
The sandy beaches of the Balearic Islands are built of a large number of organic animal remains, including foraminifera that leave their shells and create the fine white sand of the beaches.
Dead Posidonia on the beaches offer protection in autumn storms and manage to prevent the dune system from regressing. They also provide organic matter to the plants of the first dune cord.
Posidonia meadows are the place of laying and refuge for fish, crustaceans, molluscs, enriching the biodiversity of the marine environment. Posidonia meadows structure the bottom and are the habitat of more than 400 species of plants and 1000 of animals.
Posidonia meadows, among other functions, play a fundamental role in stabilizing the seabed and on wave damping. In addition, it contributes to reduce coastal erosion.
