Pencil urchin - Stylocidaris affinis

Pencil urchin is certainly one of the most curious and most characteristic species of Mediterranean urchins. Its common name derives from the shape of its thorns which resemble a classic pencil or "Lapis" as we say in Tuscany. However, these thorns are quite fragile as they are funny ...

Leopard-spotted goby - Thorogobius ephippiatus

In these two dives we met the Leopard Goby (Thorogobius ephippiatus) a sea fish belonging to the Gobidae family. In the first we are on a 45 meter seabed made up of coral reefs that rise from a sandy bottom, in the second we are on a patch full of gorgonians but isolated in a bottom of mud and debris at a depth of about 52/53 meters ...

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.

Picarel - Spicara smaris

Spicara smaris in italian Zerro, are those little fish that practically always accompany us in our dives to which we often do not give too much importance since we always hope to find more important species to film and photograph. ...

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.

Yellow and orange Parazoanthus axinellae: two different species?

Common northern comb jelly - Bolinopsis infundibulum

In this collage of videos made in two different dives a few days apart but always in the same stretch of sea we filmed one of the many species of ctenophores that inhabit our Mediterranean Sea, from some research it seems to be the Bolinopsis infundibulum or tentacled Ctenophore.  ...

Discovering new wrecks

The discovery of an unknown wreck is certainly one of the most beautiful emotions a diver can experience. However, it is an increasingly rare event now, the wrecks that can be visited with scuba loaded with compressed air are now practically all known in the various areas of the Mediterranean Sea, ...

Eggs of european Squid

The European squid or common squid (Loligo vulgaris) is a large squid belonging to the family Loliginidae. It occurs abundantly in coastal waters from the North Sea to at least the west coast of Africa. This species lives from sea level to depths of 500 m. Its mantle is up to 40 cm long.

Striped red Mullet

The striped red mullet or surmullet (Mullus surmuletus) is a species of goatfish found in the Mediterranean Sea, eastern North Atlantic Ocean, and the Black Sea. They can be found in water as shallow as 5 metres or as deep as 409 metres depending upon the portion of their range that they are in. This species can reach a length of 40 centimetres. Toxic when not cooked. Though most are only around 25 centimetres. The greatest recorded weight for this species is 1 kilogram. This is a commercially important species and is also sought after as a game fish.

Leptogorgia sarmentosa Gorgonian

Leptogorgia sarmentosa Gorgonian is quite common in the Mediterranean Sea, we often meet it during our dives, but not in the area where we explored in this video. On this seabed there are not many gorgonians, despite being the classic coralligenous bottom there is very common the red coral, Corallium rubrum ...

Trumpetfishes

The trumpetfishes are three species of highly specialized, tubular-elongated marine fishes in the genus Aulostomus, of the monogeneric family Aulostomidae. The trumpetfishes are members of the order Syngnathiformes, together with the seahorses and the similarly built, closely related cornetfishes.

Salpa maxima

Salpa maxima also arrived in the upper Tyrrhenian Sea or lower Ligurian Sea, that is, in the waters of Livorno and the province where we often dive. It is a Tunicate; at first sight it looks like a cross between a fish and a jellyfish but it is neither, it is actually a transparent invertebrate belonging to the order of the Salpidae subphylum Tunicata, coming from the deepest oceans and very rare in the Mediterranean....

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.

Schooling bannerfish

The schooling bannerfish (Heniochus diphreutes), also known as the false moorish idol, is a marine ray-finned fish, a butterfyfish from the family Chaetodontidae. It is native to the Indo-Pacific area. The schooling bannerfish is a small fish that can reach a maximum length of 18–21 cm.

Mediterranean coral reef of Calafuria

Calafuria coral reef near Livorno is one of the most beautiful coastal areas in Tuscany in the stretch from Quercianella to Livorno. Overlooking the sea, this splendid cliff continues its profile even under the sea surface until it reaches a depth of 36 meters, a short distance from the shore, and then rests on a seabed of sandy debris mixed with mud.

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.

Effects of trawling

In this dive made some time ago on a depth ranging from 40 to 50 meters deep we filmed the usual ghost nets lost close to a cliff at a distance of about 5 miles from the coast. We spent almost the entire dive on the rocks that despite the conditions seemed quite vital, ...

Red Lionfish

The Red Lionfish (Pterois volitans) is a fish venomous who live coral reef in the family Scorpaenidae, order Scorpaeniformes. Pterois volitansis natively found in the Indo-Pacific region, but has become an invasive problem in the Carribbean Sea, as well as along the East Coast of the United States.

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.

Elephant Ear Sponge

The Elephant Ear Sponge, (Spongia agaricina, Spongia lamella), resembles a relatively flat bowl. In the lower part it narrows, to form the point of attachment to the rock. The measure ranges from 14 to 80 cm in diameter with a thickness ranging from 1 to 4 cm approximately. It is an endemic species of the Mediterranean Sea that generally lives at depths between 15 and 50 meters, but we can find it up to 150 meters deep.

Masked Bannerfish

Heniochus monoceros, the masked bannerfish, is a marine ray-finned fish, a butterflyfish belonging to the family Chaetodontidae. Is widespread throughout the tropical and subtropical waters of the Indo-Pacific area from the eastern coast of Africa to Polynesia and from south Japan to New-Caledonia.

Sabella pavonina, commonly known as the peacock worm, is a marine polychaete worm belonging to the family Sabellidae. They can be found along the coasts of Western Europe and the Mediterranean. It is found in shallow, tidal waters with a bed of mud, sand or gravel. It is sometimes found on rocks or shipwrecks.

Emperor Angelfish

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.

Gold coral

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.

Yellowback Fusilier

The Yellowback Fusilier beloning to Caesionidae family, is a small to medium-sized fish which grows to about 40 cm. The body coloration is greyish blue with a bright yellow zone on the back. The yellow area goes from the forehead, between the eyes, to the tail, and includes the dorsal fin and thecaudal fin. This area corresponds more or less to the upper third of the body.

Oyster Pteria hirundo

The Pteria hirundo is a species of bivalve belonging to the family Pteriidae. The species is found in Europe, Africa and the Americas. The two valves are unequal and the lower one, to which the animal is anchored, is larger and hollow than the upper one.

It dwells in salt water up to the depth of 40m. It is exclusively found in precorralligene and coralligene communities and is very common in such communities.

Sea Whip Coral

I filmed this sea Whip coral during an underwater excursion to Maldives. The Gorgonias are an important biological indicator because they are very sensitive to pollution and sea heating; moreover, inside them we find a remarkable biodiversity composed of invertebrates of every species and of fish that use the colony both as a refuge and as a place to lay eggs safely.
