WHAT IS POSIDONIA
ALSO CALLED THE LUNG OF THE SEA
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. The seagrass meadows provide shelter for many species, produce oxygen daily, while also trapping carbon dioxide from the atmosphere (a key gas in climate change) and creating tons of biomass per year.
One of the longest-lived organisms on the planet.
A single plant can have a surface area between one end and the other of 10 km.
One of the largest plants in the Balearic Islands.
The Posidonia is a flowering plant that belongs to the family Posidoniaceae. Their long, narrow leaves spread along the bottom, grouped in bundles, and are rooted to the seabed by rhizomes. It has a long life span and can live for hundreds of years, with very slow growth of approximately a few centimeters per year. Some of them, depending on their age, can form large structures of dead rhizomes and sediment on the seabed, called mats, which are very similar to coral reefs. Unlike algae, Posidonia reproduces through the formation of fruits and seeds that are dispersed by marine currents.
With the increase in water temperature, the leaves acquire a more whitish color and are filled with epiphytes and other microorganisms. It is the season of the year with the most organic matter activity.
The flowering begins, with the development of inflorescences. The deciduous leaves detach from the bunches in large quantities due to the storms and fill the beaches with leaves.
The flowers continue to grow and some fruits begin to be seen at the end of winter, which will end up floating in the sea. At the same time, the growth of the leaves slows down.
The ripe fruits are released from the meadows and float away following the currents. After a few days, the seeds are released and sink to the bottom where they will begin to germinate.
With sexual and vegetative reproduction, the the second predominates over the first.
