Posidonia oceanica is a unique marine plant in the Mediterranean Sea
It forms underwater meadows on our coasts giving protection to the beaches from storms.
It can reproduce sexually with the flowers that release a very dense pollen and the fruits. It also does so asexually thanks to the expansion of its underground stems called rhizomes.
Even so, in recent years a massive bloom has been observed that scientists believe may be related to water heating.
The flowers that reproduce successfully create fruits known as sea olives and when they ripen they come off from the plant and travel with the currents, so the species can spread to other areas.
