Dolphins Encounter

Encountering dolphins in our seas is fairly easy, but it's one thing to spot them while sailing or see them leaping in the distance, and quite another to find them "playing under the boat", almost touching them. For us, August 15th has become a regular event. The video really was actually taken on August 16th, about 7-8 miles off the Livorno coast ...

Golden anemone Condylactis aurantiaca

Golden anemone, Condylactis aurantiaca, or sand anemone, is one of the most beautiful anemones endemic to the Mediterranean Sea, both for the colorful arms and the large size it can sometimes reach. On this dive in early August 2025, we are exploring rocky and coralligenous walls ranging from a depth of 36 to a maximum of 42 meters ...

European spider crab, Maja squinado (spiny spider crab, or spinous spider crab). This crustacean of the Majidae family was very common about thirty years ago, and specimens like the one we see in the video were very easy to find in the intertidal tidal pools, provided they had plenty of rocks to hide in and algae to grow on their backs to camouflage them from predators. ...

Blue spiny starfish

Coscinasterias tenuispina, Variable starfish or Spiny starfish is an echinoderm very common in the Mediterranean Sea. It is one of the most common starfish in the "Mare nostrum" and I would also say one of the most fascinating. Usually Echinoderms (sea urchins and starfish) have a pentaray symmetry. This species is indeed variable! ...

Peltodoris atromaculata Reproduction

When we explore our underwater reefs we are often amazed by the number of species that we find in a few square meters and as in this case even in a few square centimeters. We have said it many times that biodiversity makes a habitat and an ecosystem more stable, solid and long-lasting. Often we fail to realize the quantity of different species that live next to each other and obviously it is almost impossible to know and recognize them all.

Zero visibility - Basket star - Astrospartus mediterraneus

When we dive at depths greater than 40 meters and far from the coast, about 7.5 nautical miles, it is difficult to make predictions about sea conditions such as currents, presence of fish and marine organisms but above all visibility on the bottom. If weather forecasts are now reliable and safe over 24/48 hours, it is practically impossible to predict what will be found on the bottom once immersed.

Ghiozzo leopardo

Il Ghiozzo leopardo, Thorogobius ephippiatus, è un pesce schivo e timido ed è considerata una specie rara da incontrare per i subacquei. Noi lo troviamo abbastanza spesso nei fondali di coralligeno che variano da 38 ai 42 metri di profondità come in questo caso. Probabilmente viene considerato raro perché vive in anfratti e buche abbastanza inaccessibili alle telecamere e quindi è proprio difficile da vedere.. ...

Biodiversity

We are on an isolated patch of rock and coralligenous about 7.5 miles from the coast; the seabed varies from 49 to 52 meters, the area to explore has a surface area of ​​about a couple of basketball courts (about 600 square meters X 2). All around a sea of ​​mud and a mixture of mud/sand separates us from the main submerged reef 400/500 meters away, always on the bathymetric of 50 meters.

Red Starfish

The red starfish in this video - Echinaster sepositus - was filmed on a seabed of about 5 meters deep while free-diving, in the waters of the beautiful "Secche di Vada". We often visit these areas near the lighthouse for various reasons: the exceptional transparency of the water, the shallow depth, the presence of Posidonia oceanica that despite the frequent anchoring of boats seems to thrive and the distance from the chaotic and crowded coast in summer.

Cushion coral, Cladocora caespitosa is a typical madrepore of the Mediterranean Sea, it belongs to the Hexacorallia class and to the Cnidaria phylum., It usually has a brownish, beige or dirty white color, this one in the video is unusually very white, probably because it is "still young". It is a colony of polyps that live in symbiosis with zooxanthellae algae. The polyps form calcium carbonate deposits that form the cells in which they live and that make the madrepore grow in size ...

In the video you can see a branch of red Gorgonia, Paramuricea clavata, measuring over a meter in length, torn a few days ago from the reef where it was located, lying dying on the muddy seabed. This species and these corals when they manage to reach such dimensions are about a hundred years old. Collecting the coral from the seabed you can still see open and therefore alive polyps.
