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.

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.

Given the success of the video of this octopus (Common octopus Octopus vulgaris) made a few years ago, we decide to republish it in high resolution, eliminating some cut parts and slowing down a few moments such as that of the encounter and escape ...
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.
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.
They are often hot springs rich in mineral salts with varying temperatures. These thermal waters originate from the groundwater which, descending in depth, meet the hot rocks or are due to the condensation of the steam generated by the encounter of the water with the hot rocks.
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.
Finding cushion coral Madrepora Cladocora caespitosa is always a pleasant surprise, especially while snorkeling or during a free diving, because it means diving in a few meters deep and therefore close to the coast. ...

It feeds passively with the open tentacles, in particular of planktonic microparticles.
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.

As traditionally defined, this species of sea hare was cosmopolitan, being found in almost all tropical and warm temperate seas, including the Mediterranean Sea where first seen in 2002 and likely self-established due to increasing temperatures.
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.
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.
