Underwater attached fauna and flora of the mouth of Gironde estuary
In the previous photo gallery dedicated to the underwater fauna of the mouth of the Gironde estuary, we highlighted the fish and crustacean. In this gallery, we chose to show the flora and fauna attached to the rocks that make up the large rocky plateau.
The main feature of the region is the size of the yellow boring sponges. They can reach over a meter in diameter. These are the largest we have seen in the world. Other species of sponges are elephant ears covering the rocks. We also photographed a lot of anemones species like huge colonies of Corynactis (jewel anemones).
It is an explosion of life and color as the environment composed of silt and mud in suspension is ideal for the development of filter species.
