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.

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.

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.

Spiny dye-murex

Bolinus brandaris (originally called Murex brandaris by Linnaeus and also Haustellum brandaris), and commonly known as the purple dye murex or the spiny dye-murex, is a species of medium-sized predatory sea snail, an edible marine gastropod mollusk in the Muricidae family, the murex snails or the rock snails. This species is known in the fossil record from the Pilocene (age range: from 3.6 to 2.588 million years ago). Fossil shells of this species have been found in Cyprus, Spain and Italy. It was used by the Phoenicians in ancient times to extract imperial Tyrian purple dye.

Boops boops

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. A demeral and semi-pelagic, it can generally be found at a depth of 100 m, and infrequently down to 350 m. The Bogue reaches a maximum length of 30 cm. and a weight that can reach half a kilogram. Its color ranges from silvery green on the back to white on the belly. The fins have the same color as the back except the ventral ones which are white. On the side it has a dark lateral line under which we find four or five lateral lines of a beautiful golden color.

Spiny Starfish - Tank Star

The Martasteria or Spiny Starfish, Marthasterias glacialis, is an echinoderm of the Asteriidae family common in the Mediterranean Sea. Also called a Tank star, due to the characteristic plates bristling with thorns that distinguish it from other starfish, it has a regular shape with five arms. The body is characterized by spines of variable color: white, gray, brown, red, blue. It appears to be the largest species in the Mediterranean, capable of reaching even 85 centimeters in diameter.

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.

Sea sponge Tedania anhelans

Tedania anhelans is a sea sponge that has an arborescent shape with colors that vary from transparent to light gray or dark gray depending on the conditions and depths of the environment in which it lives and personally I also add based on age: more pale in the juvenile phase or darker in the mature phase. It is present throughout the Mediterranean Sea at a depth ranging from 10 to over 100 meters on hard substrates, in rocky walls but also, as in our case, on Gorgonians and fishing nets abandoned for several years. In fact, the Tedania sponge reproduces very easily.

Catshark egg case

During a scuba dive I encountered this Catshark egg attached to an abandoned anchor rope on the seabed. The Catshark is a predominantly nocturnal fish that hides in the burrows and ravines of submerged cliffs during the day. Typically this small shark fixes its eggs to the various Gorgonians to make the most of the sea currents. In this case, as there were no Gorgonians in the seabed, he used the rope abandoned on the bottom by a boat.

Basket Star

The Basket Star is characterized by five tentacles, each branched several times, with which it clings to the branches of the soft corals and which are opened at night to feed on. The body has a diameter that can reach 8 centimeters, with the complete opening of the tentacles the maximum width of the entire animal can reach 80 centimeters. It feeds passively with the open tentacles, in particular of planktonic microparticles.

Too many fishing nets lost

The marine environment is affected by all kinds of pollution that has always been caused by human activities but from the industrial era to the present day it has developed exponentially to the point that we may consider not to return. A human activity in direct contact with the sea is certainly represented by professional fishing. Fishing is generally practiced by trawl nets or fishing net. The fishing net net is certainly the most compatible because it is practiced selectively and more respectful to the environment.

Deadly Ambushes at Sea

Deadly Ambushes at Sea! It is the struggle for life! As we know, the big fish eats small fish, probably the weakest one, also carrying out a natural selection and a biological balance that has always occurred in a bloody way in nature. Unless human intervention, as more and more often happens in recent years, does not interrupt the biological cycle and thus create imbalances in nature which, as we know, eventually backfire the human.
