Picasso triggerfish Rhinecanthus aculeatus

The Lagoon triggerfish (Rhinecanthus aculeatus), also known as the blackbar Triggerfish, the Picasso triggerfish, or the Picassofish, is a triggerfish, up to 30 cm in length, found on reefs in the Indo-Pacific region. This species has been studied in a range of research contexts, from locomotion to color vision research. Lagoon triggerfish live in the reefs and sandy areas of coral reefs, where they eat just about anything that comes along, mostly including invertebrates and reef algae.

Spiny Oysters Spondylus gaederopus

Spondylus gaederopus is a species of marine bivalve mollusc, a thorny oyster in the family Spondylidae. This species is endemic to the Mediterranean Sea. Spondylus gaederopus attaches itself to the substrate with its lower valve, which is usually white, while the upper valve is usually purple. Specimens that are all white, or all purple do, however, exist.

Bogues that devour a Barrel jellyfish

Boops boops commonly called the bogue, is a species of seabream native to the eastern Atlantic. Its common name in most languages refers to its large ("bug") eyes. The species is found off the coasts of Europe, Africa, the Azores and the Canary Islands, from Norway to Angola, and in the Mediterranean and Black Seas. It avoids brackish waters such as the Baltic Sea. A demeral and semi-pelagic, it can generally be found at a depth of 100 m, and infrequently down to 350 m.

Olindias phosphorica, or Cigar jellyfish, is a species of hydrozoan from the central and eastern Atlantic and the Mediterranean Sea. The Mediterranean sea is a predominantly warm body of water, thus Olindias phosphorica is a warm-water Jellyfish. Global warming has facilitated the proliferation of the species throughout the Mediterranean sea.

Hermit crab in Phalium glaucum shell

The Pagurus belongs to the Paguridae family. Hermit crabs are crustaceans with a curved and soft abdomen. It lives in empty shells of gastropods on which it sometimes attacks sponges or poisonous actinias to camouflage and defend itself. In case of danger it can withdraw completely inside the shell. The end of the tail of the hermit crab is suitable for strongly grasping the shell it always carries with it. When it grows and the size of the shell is no longer suitable is search for a new shell to protect yourself. In the video we see a hermit crab that has taken possession of the shell of the sea snail Phalium glaucum, a marine gastropod mollusc of the Cassidae family

Calyx nicaeensis Goblet Sponge

I met this Calyx nicaeensis, Goblet Sponge, during a dive in the reefs of the Secche di Vada near Livorno. The name owes it to its characteristic goblet shape. According to some experts, this sponge has become extremely rare in the Mediterranean because it requires very stable water temperature and biological conditions: small variations are enough to decree its disappearance. We all know by now that climate change has a heavy impact on biological life, but few seem to realize that it also affects the deep sea.

Red Squirrelfish

We met the Red Squirrelfish (Sargocentron rubrum) in the sea of ​​Cyprus while snorkelling among the rocks of the island. We did not expect to have this meeting in the Mediterranean because it is a tropical fish present in all tropical seas and in particular in the Indian Ocean and the Pacific Ocean. The reason for this sighting, as indeed for other tropical species now present in the Mediterranean, we owe it to the climatic warming of the sea, which creates favorable conditions, and to the Lessepsian migration: that is, to the entry and stabilization of animal and tropical species from the Channel of Suez.

Red sponge Spirastrella cunctatrix

The Red sponge or spirastrella (Spirastrella cunctatrix) is a sponge of the Spirastrellidae family belonging to the demospongiae class. It is an encrusting red-orange sponge (which can sometimes turn green, blue and grey), characterized by very evident channels that culminate in the osculum, rough to the touch due to the presence of spicules. It can also cover large expanses of seabed. It can be confused with the encrusting forms of Crambe crambe. It is common in the Mediterranean Sea up to 30 meters, sometimes present even at greater depths, in dimly lit, rocky environments, often in caves. Often associated with coralligenous and Astroides calycularis.

Acanthurus bariene is a tropical fish also commonly known as the bariene surgeonfish, blackspot surgeonfish, or eyespot surgeonfish. It was first named by René Primavère Lesson in 1831. This species is widespread in the tropical Indo-Pacific from Mozambique and the Maldives in the west to the Solomon Islands in the east and reaching north to the Ryūkyū and south to the Australian Great Barrier Reef. The habitat of this fish is the coral reefs where it lives on the outer side in depth. The juveniles live in shallow waters and in areas protected from the waves, finding refuge among the soft corals. It can be found between 6 and 50 meters of depth, rarely above 15 meters and usually below 30.

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.

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.

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.

Reteporella grimaldii is a species of bryozoans  in the family Reteporidae.  It is composed of a colony of small animals that form a limestone substrate which takes the form of a refined lace. Hence the name of sea lace. The animals that compose it live on organic particles, plankton, filtering the water carried by the current. The Reteporella can take on different colors based on the species and the environmental conditions in which it lives. We have little information on the environment in which it lives but we can say with certainty, based on our direct experience, that it is possible to meet it from 10 meters up to 100 meters deep. The video we show you was shot in the Mediterranea Sea at 56 meters deep.

Orangespine Unicornfish Naso lituratus

Naso lituratus is a species of fish in the family Acanthuridae, the tangs and unicornfishes. Its common names include barcheek unicornfish, naso tang, and orange-spine unicornfish. Unique to members of Acanthuridae, including Naso lituratus, are the Epulopiscium bacteria. These bacteria influence the digestion of Naso lituratus, helping them process the algae in their diet. Naso lituratus can be found in the Indian Ocean and the Pacific Ocean. This species can be easily recognised by two bright orange forward-hooked spines on the caudal peduncle (the tail base), its orange lips and black face mask. The body is brownish grey with yellow nape and there is a broad black band on the dorsal fin. It reaches about 45 cm in length.

Mediterranean coral reef

The Savalia savaglia, commonly known as gold coral, is a species colonial in the family Parazoanthidae. This organism is commonly called "false black coral". It owes its name to its ability to produce a dark-colored horny skeleton, usually blackish. The colonies are generally settled on pre-existing gorgonians skeletons and can grow with ramifications that far exceed one meter in length. The polyps of this coral have six tentacles which is why the species is part of Hexacorallia group. They are bright yellow or whitish, and very large and showy (2-3 cm high), similar to those of Parazoanthus axinellae. Sprout very well from the tissue that lines the skeleton (coenenchyme) and have available alternates, showing smooth tentacles. The polyps do not fall as those of other species but can retract and close in on themselves.
