Description

The crater gathers different kinds of dives: wall, cavern and shoal. Following a vertical wall we reach a rocky arch (-37 mt) where we can find the red lance urchin Stylocidaris afflnis, the sponge crab Dromia pesonata, the fan bryozoan Hornera frondiculata. Behind the arch we are Inside the crater. We see big blocks one time ceiling of the cave now collapsed. On the right side we nave a particu­lar general view. Moving anticlockwise we arri­ve at a second arch (-39 mt) and we go out of the crater. Keeping the left and looking at the blue, we frequently meet a family of brown meagres Sciaena umbra. We can get very dose to admire their elegance. Re ascending until a depth of twenty metres, it seems to be on the top of a shoal. We face a plateau of Neptune grass Posidonia oceonica (not a seaweed but an aquatic flowering and fruit bearing plant) hiding big striped (golden) groupers Epinephelus ale­xandrinus and a big dentex Dentex dentex. Swimming over the crater we reach the south part of Quail's Point where the daisy or plumose anemone Cereus pedunculatus, the green alptasia or trumpet anemone Aíptasia mutabilis and the fat anemone Condylactis auranbaca, Iwe in the holes. Big swarms of salemas Sarpa salpa accomplish spectacular evolutions. From the Ilmestone rock, the yellow or red boring sponges Cliona sp, come out.
