Barrel Jellyfish

Rhizostoma pulmo, Barrel Jellyfish is one of the most common jellyfish in the Mediterranean Sea. In the video we see it swimming under the surface of the water letting itself be carried away by the current and the waves, this jellyfish is completely harmless and we can easily touch it on the umbrella, the tentacles are however slightly stinging so it is advisable to stay away from it even if the irritations however, they resolve within a few minutes. ...

Blue Sponge

Phorbas tenacior, Blue sponge is one of the first organisms to colonize new wrecks or any submerged vertical surface not yet colonized by marine organisms. In this video we see it on a wreck about 30 meters deep. Probably this wreck is quite recent, perhaps sunk between the first and second world wars, has several colonies of sponges including the blue encrusting sponge, which seems to prefer vertical walls away from direct sunlight. Obviously we also see it next to other species of sponges of the genus Tedania and Verongia but if we look at the part of the prow the presence of Phorbas tenacior ...

Cleaning station for Titan triggerfish

In this video we show you a particular form of mutualistic symbiosis, quite widespread in the marine aquatic environment, between a Labroides dimidiatus cleaner fish and a Titan Triggerfish. The cleaning operations constitute a mode of relationship in which the cleaner fish feeds on the ectoparasites, on the now dead skin tissue flaps and on the food residues of the host, which undergoes its care. The "customer", i.e. the fish being cleaned, gains a better fit of its body, while the cleaner gains nourishment.

Haliotis tuberculata lamellosa - Haliotis Abalone

Abalones or Haliotis are gastropod molluscs of the genus Haliotidae. In Italy the name that is used is Ear of Venus, a name that derives from the beauty of the pearlaceus side inside the shell. The external side as seen is completely different and looks like a concretion or a rock, and it is precisely for this reason that they are difficult to identify on the seabed or attached to rocks. Our Ear of Venus was in a hole a few meters deep and obviously we only found the shell, probably the residue of the usual octopus meal. ...

Moray

Moray Eel is often identified as an aggressive and dangerous fish but as we can see from this video it is anything but an "evil titan of the seas". We are on a rocky and coral seabed typical of the Mediterranean Sea at about 46/48 meters deep, where we often meet the Mediterranean moray Moray eel, Muraena helena, and in this case it is seen in the typical diurnal pose, i.e. with the head and a small part of the body outside its den while it rests from the nocturnal raids in search of food but always vigilant in controlling its own territory. ...

Starfish Astropecten jonstoni

Astropecten jonstoni is a sea star of the family Astropectinidae. Starfishes of genus Astropecten live on mobile seabed (sandy, muddy or gravel seabed) and they remain largely buried under sediment during the day. During the late afternoon and the night starfishes go out to hunt mainly bivalve molluscs, which are their favourite preys. Unlike other Astropecten, this species is active and easy to find during day, especially in early morning and late afternoon. However, if they perceive a danger or if they are disturbed, in this case by a diver who is snorkelling as you can see in the video we are showing you, they tend to get covered up quickly. This species lives only in the Mediterranean Sea and it prefers sandy seabed at low depths as between 1 and 12 m.

Submerged marine life

Under the surface of the sea an exuberant life is "hidden" that develops in three dimensions, full of countless beings so different from each other where the competition for life sometimes becomes dramatic but always finds a delicate balance of coexistence. The interest in observation leads us to appreciate a wonderful aquatic life, both animal and plant, present at all depths.
