Blue damselfish

Even in this summer of 2025, like every summer, we witness the birth and growth of the Black Damselfish, Chromis chromis, the only one of its kind Pomacentridi - Pomacentridae - in the Mediterranean Sea. In these sequences we see it in its shining electric blue livery, when the little fish are still small, a few weeks after the hatching of the eggs laid in winter, spring by the females and guarded by the male until the birth ...

Blow lugworm egg Arenicola marina

The blow lugworm (Arenicola marina), also known as sandworm, is a large species of marine worm. Its coiled castins are a familiar sight on a beach at low tide but the animal itself is rarely seen except by those who, from curiosity or to use as fishing bait, dig the worm out of the sand. In the video I made you can see a egg blow lugworm, Arenicola marina, anchored to the Mediterranean sea floor at about 40 cm depth.

Astrospartus mediterraneus

In the video I made you can see it with the almost complete opening of the arms because even though it was made during the day, I was at a depth of over 80 meters where the light is very attenuated. Beautiful and elegant, when it is open, it seems to see a refined female embroidery lying on the Red Gorgonia enhancing the beauty of the images presented to the diver.

Pelagia noctiluca can be described as a marine organism with the ability to glow in the dark (bioluminescence). It is found worldwide in tropical and warm temperate seas.

Octopus in den

In this short video we show you a "crafty octopus". That these animals are very intelligent is now well known to everyone; in this case the octopus he are organized itself with two dens close to each other. But if we carefully observe the video we can think that it is the same den with two exits, the main one and the secondary one that could be the "emergency exit".

Special mission mediterranean Spiny Lobster

It is late August and Summer is the period in which many marine organisms prepare for procreation. We have therefore decided to reach a deep Mediterranean coral reef, over 7 miles from the coast. The procreation have pushed these crustaceans to gather at the same time and in the same place. Procreation, in fact, occurs at the end of the Summer and in the Winter the larvae are born, which immediately reach the seabed that will host them for the rest of their lives.

Peltodoris atromaculata Reproduction

When we explore our underwater reefs we are often amazed by the number of species that we find in a few square meters and as in this case even in a few square centimeters. We have said it many times that biodiversity makes a habitat and an ecosystem more stable, solid and long-lasting. Often we fail to realize the quantity of different species that live next to each other and obviously it is almost impossible to know and recognize them all.

Despite the poor visibility our torches manage to bring out all the colors of the underwater world.

Zero visibility - Basket star - Astrospartus mediterraneus

When we dive at depths greater than 40 meters and far from the coast, about 7.5 nautical miles, it is difficult to make predictions about sea conditions such as currents, presence of fish and marine organisms but above all visibility on the bottom. If weather forecasts are now reliable and safe over 24/48 hours, it is practically impossible to predict what will be found on the bottom once immersed.

This fish belonging to the Serranidae family (the same as the Mediterranean Brown Grouper) lives on coralligenous seabeds and begins to be present from 30 meters deep onwards. However, it can be found up to 200 meters and in our scuba dives it is practically omnipresent. ...

Leopard-spotted goby

Leopard gobi, Thorogobius ephippiatus, is a shy and timid fish and is considered a rare species for divers to encounter. We find it quite often in coralligenous seabeds that vary from 38 to 42 meters deep as in this case. It is probably considered rare because it lives in ravines and holes that are quite inaccessible to cameras and therefore it is very difficult to see. ...

Marine plastics pollution is a type ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean. Eighty percent of marine debris is plastic. Microplastics and nanoplastics result from the breakdown or photodegradation of plastic waste in surface waters, rivers or oceans...
