Aplysia depilans - Sea hare

We publish another encounter with the Sea hare, Aplysia depilans, this time which took place on a depth of about 42/45 meters. We are on a not very high rock wall about 4/5 miles from the coast where, due to the now increasingly present mucillage, animals and marine organisms seem to have disappeared. ...

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.

Demosponge

Demosponges are the most diverse class in the phylum Porifera. They include 76.2% of all species of sponges with nearly 8,800 species worldwide (World Porifera Database). Sponges, contrary to what one might think at first sight, are very simple multicellular animal organisms very similar in shape and appearance to plant organisms. There are no apparatus in the sponges and there is no trace of a nervous system.

Cave with Yellow cluster Anemone

I met these beautiful colonies of Parazoanthus axinellae during a snorkeling activity in the coastal caves of the island of Pantelleria. In my experience as a diver I have never encountered these sea daisies at almost surface level; evidently in this case the colony of Parazoanthus axinellae has found particularly favorable environmental conditions of light and sea currents

Unknown marine organism

During a scuba dive in a beautiful Mediterranean coral reef of Savalia savaglia and Paramuricea clavata, at a depth between 72 and 76 meters, I met this unknown marine organism for the first time. Curiosity prompted me to carry out a series of searches to understand precisely what I was dealing with. Research has not yielded a satisfactory answer. The questions I asked myself were many. Based on my experience of many years of scuba diving it could be an animal belonging to the phylum Prorifera.

False coral Myriapora truncata

Myriapora truncata, also known by its common name false coral is a species from the genus Myriapora. The species was originally described by Peter Simon Pallas in 1766. Myriapora truncata is a common species on rocky environments from the water surface to a depth of 60 meter, where it forms calcareous colonies. It has a bright red colour which earned it its common name of "False coral". Studies suggest that M. truncata seem well able to withstand the levels of ocean acidification predicted in the next 200 years. Myriapora truncata is the source of 4 polyketide-derived metabolites.

Alifu Dhaalu Atoll to Maldives

This video was made in December 2022 during a short vacation I spent on Angaaga island; I must say that the weather was not what I wanted and therefore, not being able to do scuba diving with aqualung, I dedicated myself to snorkelling in the coral reef that surrounded the island. The small island of Angaga is located in the center of Alifu Dhaalu Atoll, in the southern part of Ari Atoll. This small island has been used exclusively as a tourist resort for those who intend to spend a holiday in the Maldives.

Charonia tritonis - Giant triton

We are on some isolated rocks at a depth of 40/46 meters, where we have found two beautiful specimens of Charonia tritonis, Giant mediterranean triton.  This is the mollusk and consequently the largest shell in the Mediterranean Sea. In this dive we met two of them, we filmed the first one casually on the wall we were exploring, we realized watching the footage that we passed by without seeing it. The second was inside a hole from which we moved it to try to film it better. ...

Octopus vulgaris - Common octopus

We have filmed Common octopus, Octopus vulgaris, several times on intotheblue.it but each encounter with this cephalopod mollusk is always unique and different from the previous ones. In this case, in fact, the octopus was so well camouflaged on the seabed that it was not possible to see it from just a few meters below the surface. ...

Ornate wrasse male with females

The ornate wrasse, Thalassoma pavo, is a species of wrasse native to the rocky coasts of the eastern Atlantic Ocean and the Mediterranean Sea. This species is of minor importance to local commercial fisheries, is also popular as a game fish, and can be found in the aquarium trade.

Diving on Silvio's Wreck

Silvio wreck is now reduced to very bad conditions due to the time that has passed but, above all, due to the fishing boats that cause continuous hooks with their trawl nets and then, in an attempt to recover them, cause further damage to the structure of the tug; the wreck is in fact almost completely surrounded by fishing nets. As you can see from the video, the seabed on which it is located is a muddy seabed and a few movements by the diver are enough to lift the mud and make visibility poor; therefore considerable experience is required to avoid accidents and dive in complete safety.

Lipophrys nigriceps - Rabosa negra

This little minnow is one of the most common Blennid species in the Mediterranean Sea.

Mauve stinger

In this video made in summer we filmed Mauve stinger or Purle jellyfish, Pelagia noctiluca luminous jellyfish. We stopped to film three specimens we met during the same swim, snorkelling in the waves, trying hard to avoid contact with these jellyfish. In fact, the Pelagia noctiluca - Luminous jellyfish - is the most dangerous jellyfish in the Mediterranean Sea, contact with its tentacles can cause painful skin irritations and burns. ...

Australian spotted jellyfish

Phyllorhiza punctata, also known as the floating bell, Australian spotted jellyfish, brown jellyfish or the white-spotted jellyfish, is a species of jellyfish belongs to the Rhizostomatidae Family and the genus Phyllorhiza.

It is generally common, but uncommon or rare (locally even absent) in the northwestern Mediterranean and in the Adriatic Sea. It prefers relatively warm temperatures and there is an ongoing northward range expansion, probably because of global warming. The primary adult habitat is rocky reefs, especially in areas with macroalgae, but they may visit adjacent seagrass patches. Juveniles also occur more widely in the latter habitat.

Mediterranean Parrotfish female

This video was shot between the reefs of the island of Pantelleria in the Sicily Channel. In this stretch of sea it is easy to meet parrot fish because the climatic conditions of the sea make it their favorite habitat. The females of Sparisoma cretense are very showy due to the beautiful colors of the livery and because, unlike the males, they are less shy and therefore move us between the reefs with more ease and it is easier to meet them while snorkeling.

European conger

Conger (European conger - Conger conger) is one of the first marine species of the Mediterranean Sea that colonizes wrecks and we met it right among the plates of one of the many wrecks on which we often dive.

The struggle for life

This video made in the Maldives shows us an octopus as it comes out of its den to go hunting for food. While out he is attacked by a redtoothed triggerfish and thent has to give up his lunch and immediately take shelter in an emergency shelter to try to save himself. The video is interesting because it highlights the struggle for life that occurs every day in nature and where the predator must necessarily be careful to prevent becoming the prey of another animal.

Mediterranean jellyfish or fried egg jellyfish - Cotylorhiza tuberculata

Like all summers we witness the "terrible proliferation of jellyfish" that scares us so much. Mediterranea Cassiopeia (Cotylorhiza tuberculata) (Mediterranean jellyfish, Mediterranean jelly or fried egg jellyfish) that we see in this video is a scifomedusa of the Cepheidae family, and is totally harmless. ...

Flathead grey mullets among the boats

Flathead grey mullets it is a fish able to withstand wide variations in salinity, in fact we find it regularly in marine waters, fresh or brackish waters. Extremely adaptable to all environments; we often find it at the mouths of rivers, in lagoon areas where sea water mixes with fresh water from the hinterland and inside bays and harbors. We met him among the boats of the small port of Castiglioncello: a well-known tourist and seaside resort near Livorno. Usually shy and suspicious, because often the object of predatory fish hunting, in this case he let himself be approached by the diver's camera who took the opportunity to make a close encounter.
