Barrel jellyfish Rhizostoma pulmo
Jellyfish are always fascinating! whether they are dangerous or completely harmless like the Barrel jellyfish (Rhizostoma pulmo). Every time we find this jellyfish and publish the film on intotheblue.it (and on the YouTube channel) we register a lot of visits and receive many emails from curious people, simple enthusiasts, divers and marine biologists. So we are happy to publish this video even if it is not exactly recent, in fact made in 2022. ...

Beadlet anemone
Beadlet anemone - Actinia equina - is one of the most common species of anemone or actinia in the Mediterranean Sea. It lives in the intertidal zone. The intertidal zone, also known as the shoreline, is the area above the water level at low tide and underwater at high tide. Simply put it is the area within the tidal range. ...

Emperor Angelfish Pomacanthus imperator
The Emperor Angelfish (Pomacanthus imperator) is a species of marine angelfish. It is a reef-associated fish, native to the Indian and Pacific Oceans, from Red Sea to Hawai and the Austral Islands. This species is generally associated with stable populations and faces no major threats of extinction. It is a favorite of photographers, artists, and aquarists because of its unique, brilliant pattern of coloration.

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.

Mnemiopsis leidyi invasion
And also this summer we found ourselves faced with the now regular invasion of the Sea walnut, Mnemiopsis leidyi (warty comb jelly or sea walnut). This phenomenon is becoming more and more frequent throughout the summers, and it is now clear that the main cause of these invasions is the increase in sea temperature. ...

European conger
Common conger is a bony sea fish belonging to the Congridae family. Here we see it in its lair at a depth of about 52 metres, on a muddy seabed at the base of a beautiful vertical wall, even a few meters high, of rock and coral. As we see, the wall is colonized by many Mediterranean organisms such as sponges, corals and gorgonians, full of caves and ravines where these fish seek shelter during the day and food during the night. ...

Protula tubularia
Protula tubularia is a sedentary Mediterranean polychaete also present on the two sides of the Atlantic and in other seas. The vermiform body is protected by a solid calcareous tube, up to 1 cm broad, which the animal builds around, after having chosen for fixing itself a ridge where the currents rich in plankton pass. From the tube in which it moves, which is the house chosen for life, two elegant gill crowns come out ...

Bluefish
Bluefish is the "predator" in fact it feeds exclusively on other fish and cephalopods. Its favorite preys are mullets even if in this video we see it hunting in a few meters of depth, trying to capture salemas present in numerous specimens in a herd. As always, the encounter is lightning-fast and lasts only a few seconds, in fact the Serras do not let themselves be distracted when they are hunting and it is extremely difficult to get close. By slowing down and enlarging the video we managed to extrapolate some images of this splendid fish. ...

Blue Mediterranean chromis
Also in this summer, as indeed in all the months of July and August in the Mediterranean Sea, we can witness what we have always considered a spectacle of nature and of the "Mare Nostrum". That is the birth of the Chromis chromis or as we often say of the blue Mediterranean chromis. These little fish are truly to be admired thanks to their intense electric blue. ...

Luria sea snail
Meeting Luria lurida is becoming more and more difficult, then finding the shell with the mollusc inside alive is practically a very rare event. In the video we obviously see the Cyprean shell without the animal but given the sheen of the shell this mollusk was probably recently eaten by some predator, probably the usual octopus. ...

Paramuricea clavata - Red gorgonian - Reproduction
In this dive of August 15, 2023 we filmed an event that has not yet been documented much in our Mediterranean Sea. This is the reproduction of the red Gorgonian (Paramuricea clavata). Like every year in summer, this beautiful coral reproduces with the synchronized emission of male and female gametes released by the polyps which open by extruding thin semi-transparent filaments exceptionally long up to 5 cm. ...

Purple jellyfish
Given today's many views on an article from a while ago: Purple Luminous Jellyfish - Pelagia noctiluca, we're publishing today's meeting with the infamous Purple Jellyfish. On other occasions we were able to get closer to the jellyfish and film it much closer. As you can see today it wasn't really the case since our jellyfish had completely outward stinging tentacles, and as you can see in the video dangerously almost a meter long. ...

Red starfish
Finding a starfish is one of the first experiences a diver can have, especially the Red starfish - Echinaster sepositus - one of the many species among the most common in the Mediterranean Sea. It is one of the first encounters, but even the most experienced divers always find this species of echinoderm fascinating. However, when they meet, some precautions must be taken to avoid causing damage to these splendid starfish. Surely picking them up with some care, handling them and forcibly removing them from the substrate on which they are located can lead to damage ...

Squid eggs
In these two different dives at a depth ranging from about 40 to 50 meters, we filmed the eggs of the European squid (Loligo vulgaris) laid in completely different ways. In the first dive we found them in what would appear to be the optimal situation, i.e. in a hole near the red Gorgonian (Paramuricea clavata), therefore certainly in an area where a constant flow of current and therefore oxygenation is guaranteed ...

Blue crab - Callinectes sapidus
Even we at intotheblue.it could not miss the infamous and by now famous this summer, Blue Crab - Callinectes sapidus - also known as Blue King Crab. We filmed it after several reports, on the stretch of coast between Vada and Rosignano Solvay, luring it with a bait to film it with the camera. This alien species has colonized the Mediterranean for at least fifty years but has spread by invading the coasts in recent years perhaps precisely because of the now inevitable warming of the waters of the Mediterranean Sea. ...

Cladocora caespitosa - Cushion coral
Cladocora caespitosa, Cushion coral Madrepora, is the typical madrepora of the Mediterranean and is also considered the most important endemic bioconstructor coral of the Mediterranean Sea. It forms colonies often isolated, but sometimes capable of forming aggregations. Low densities are recorded in the Adriatic (populations are slightly declining), while in other areas the species is in great expansion ...

Mediterranean barracuda and European barracuda
European barracuda, Sphyraena sphyraena (Linnaeus, 1758), also known as the European barracuda, is the endemic species of the Mediterranean Sea. Mediterranean barracuda, Sphyraena viridensis, commonly known as yellow-mouthed barracuda, is instead the alien species, that is, the one that was limited to a restricted basin of the eastern Atlantic (Cape Verde, the Canary Islands and the Azores) ...

Leerfish or Garrick - Lichia amia
We had been trying for a long time to film Leerfish or Garrick - Lichia amia - one of the most beautiful and most elusive Carangidae endemic to the Mediterranean Sea. It is a pelagic species but, like all carangids, Leerfish usually approaches the coast at the beginning of June, disappears, returns at the end of August until October. In the video we met her during the final phase of a storm, when the large carangids of the Mediterranean (Learfish and Amberjack) approach the coasts in search of food, this is why their elusive nature allows them to be spotted by divers only for a few moments and then disappears into the blue. ...

Murex trunculus or Hermit crab?
Often while snorkelling it happens to find some shells and in the Mediterranean it is easy to meet the Murex shell only that we do not always find the mollusk inside, Murex trunculus or Hexaplex trunculus, but the classic Hermit crab which has appropriated a bigger, more beautiful but above all safer house. We have probably found the Clibanarius erythropus, red-legged hermit crab, devil hermit crab or coast hermit crab, one of the most common hermit crabs in the Mediterranean but rarely of such dimensions as to be able to easily drag a shell like that of the Murex. ...

Spiny starfish Martasteria
Martasteria or Thorny starfish (Marthasterias glacialis Linnaeus, 1758) is one of the most common starfish in the Mediterranean Sea, it is an echinoderm of the Asteriidae family. In this video we see it lying on a cliff that varies from 41 to 49 meters deep, rich in red Gorgonians of the Paramuricea clavata species and the classic yellow sponges of the Verongia species, therefore a guaranteed show of colors at the expense, however, of the visibility of the water about two or three meters. ...

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.

Pompano - Trachinotus ovatus
The Pompano, Trachinotus ovatus, is a bony sea fish belonging to the Carangidae family. In the video we see a specimen trying to capture anchovies, Engraulis encrasicolus, with rapid and lightning attacks. Distribution and habitat It is widespread throughout the Mediterranean Sea and in the eastern Atlantic Ocean between the English Channel and tropical Africa. It has very rarely been found as far north as Sweden and Norway. In Italian waters it is very common. It is pelagic but typically coastal, ...

Garfish
Garfish, Belone belone is a bony sea fish belonging to the Belonidae family. It commonly lives in the Mediterranean Sea and the eastern Atlantic, in coastal areas around the Canary Islands, the Azores, Madeira and Cape Verde, as well as in the Black Sea and the Sea of Azov. Garfish is a pelagic species, i.e. it lives mostly in the open sea and usually in the Mediterranean it approaches the coast from the end of August until October. ...

Acanthurus bariene
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.

Cylinder anemone
Cylindrical or Cylinder anemone, Cerianthus membranaceus, (anemone cilindrico), is one of the species of deep sea anemones typical of the Mediterranean Sea. Autochthonous to the Mediterranean Sea, it can also be found in the eastern Atlantic Ocean, on sandy or muddy bottoms from a few meters up to 40 meters deep, even if in this dive we are on a rock and sand bottom that varies from 45 to 48 meters deep. ...

Red scorpionfish
In this beautiful dive we met many specimens of Red scorpionfish, Scorpaena scrofa, and these that we see in the video are particularly large, almost a meter long. This species is typical of the Mediterranean Sea and we have met them at a depth of 52/53 meters in what would be their ideal habitat, i.e. the typical coralline seabed full of holes and ravines where Gorgonians and sponges thrive on which they settle perch waiting to launch some ambush to fish like the red damselfish.

Phalium glaucum seashell
Phalium glaucum, common name the grey bonnet or glaucus bonnet, is a species of large sea snail, a marine gastropod mollusk in the family Cassidae, the helmet snails and bonnet snails. This species lives on sandy bottoms with seagrass meadows, in intertidal and shallow subtidal areas to a depth of about 10 m. Shell of Phalium glaucum can reach a length of 60-147 millimetres.

Curiosity of the octopus
Common octopus, Octopus vulgaris, is an extremely curious animal towards everything that happens in its territory and this makes it one of the most intelligent species in the underwater world. In this video we see him emerge from his den intent on studying the camera specially placed on the seabed to test his curiosity.We identified it thanks to the presence of some fish such as the Sciarrano (Serranus scriba) and Donzella pavonina (Thalassoma pavo), intent on scrutinizing its den probably waiting for some food waste. ...

Wanderers of the sea - Glass Ctenophore
Also this summer we met one of the many "wanderers of the sea" that is one of those species such as tunicate jellyfish and ctenophores that let themselves be carried away by the currents, reducing their movements to a minimum. We are talking about the Glass Ctenophore - Bolinopsis vitrea - which we have already filmed some time ago, this specimen seems quite old but as soon as touched it showed us the splendid reflections of bioluminescence that the ctenophores activate when they are stimulated. ...

Sea pen Pennatula phosphorea
Sea pens are colonial marine cnidarians belonging to the order Pennatulacea. There are 14 families within the order and 35 extant genera; it is estimated that of 450 described species, around 200 are valid. Sea pens have a cosmopolitan distribution, being found in tropical and temperate waters worldwide, as well as from the intertidal to depths of more than 6100 m.Sea pens are grouped with the octocorals, together with sea whips (gorgonians).

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. ...

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.

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. ...

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.

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 ...
