As you can imagine from the name, the main feature of the shoal is the presence of a great number of huge European fan worms. The wall of this small shoal is populated by gorgonians (yellow and red), sea anemones, and Posidonia. Often, in the blue, during the descent, it is possible to meet the sunfish.
On the rock, it is possible to see various species of stars like the common brittlestar, the spiny starfish, and the more common red starfish, and there are also many lobsters.
