For over a century, the Mediterranean coast has been attracting more and more people, but few of them take the time to discover and respect its many riches. The transparency, temperature and quality of the bathing waters invite you into a colourfull world of tranquillity.
A paradise of scuba diving with many natural spots, notably around the “Two Brothers” rocks, La Seyne sur Mer holds many other surprises in store: wreck diving, flipper, mask and snorkelling excursions…

PROTECTED SPECIES…
(The trapping, removal, or sale of these species is completely prohibited and illegal.)

…flora

• Posidonia herbarium is not an algae but a flowering plant. It forms vast undersea herbaria that are essential to the Mediterranean marine ecosystem. They can grow to 40 metres in depth and protect the shoreline from erosion. Posidonia herbaria are a source of oxygen and are spawning grounds and nurseries for many animal species. 
• Cymodocea resembles Posidonia but its leaves are thinner.

…fauna

• Great mother of pearl
• Flat lobster
• Sea date (European date mussel)
• Giant limpet
• Diadem sea urchin
• Grouper
• Cetaceans
• Loggerhead turtle
• Monk seal

RESPECTING NATURE…
…sea urchins
Along the French shoreline collecting is authorized from the first of September to 30th April with the exception of Bouches-du-Rhône where collecting is only authorized from 1st November to 31st March.
Quantities are limited to 4 dozen per person on foot and 12 dozen per sea boat.
The minimal size of capture is 5 cm in diameter without spines.
It is forbidden to sell what is caught.
