Bouches-du-Rhone

France

Tunnels on the eastern side at the bottom; great wall on the northern side.

Two biological interests:
- Oculina patagonica is a hard coral (like those on tropical waters!) that has been imported on the eastern side of the rock, near 4m deep. Brown colour, approx 4/5m².
- Savalia (Gerardia) savaglia is an arborescent anemone that grows on gorgonians (both red an white). You can find this rare specie on the northern wall of the rock. Easy to find cos of the pale yellow/white colour in the middle of the red gorgonians.

Small rock closed to Riou island (SE). Part of the three rocks named "Les imperiaux".
