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. ...

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. ...

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. ...

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 ...

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. ...

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.

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 ...
