Scientific name: Posidonia oceanica

It is an aquatic plant with roots, trunk, leaves, flowers and fruit. It is endemic to the Mediterranean and we always find it in well-lit areas up to 80 meters deep. Neptune grass takes root on the sand bottoms, fixing it, which is why it is very important in the creation of beaches.

Currently the Posidonia meadows are in clear regression due to water pollution, trawling and boat anchoring. It houses up to 400 types of algae and thousands of animal species.

Curiosities

Neptune grass suffers greatly in polluted waters, so they are indicators of the environmental quality of the water. Historically they have been used to build the roofs of local houses due to their insulating capacity and their ability to prevent the reproduction of bugs.
