Study Notes

Known as Neptune grass or Mediterranean tapeweed, Posidonia oceanica is a vital seagrass species in the Mediterranean Sea.
These meadows form dense underwater ecosystems that are essential for marine biodiversity.

Water Clarity: Posidonia oceanica meadows help maintain water clarity by trapping sediments and filtering pollutants.
Habitat Provision: They provide essential shelter and food sources for a myriad of marine species, including fish, crustaceans, and mollusks.

The seagrass beds stabilize the seabed, which protects coastlines from erosion, thereby safeguarding coastal ecosystems and human infrastructure.

These meadows host a rich variety of marine life, making them significant for maintaining ecological balance and resilience in the marine environment.
Posidonia oceanica contributes substantially to the overall productivity of marine ecosystems in the Mediterranean.
