Unknow species

This video was taken last Saturday (14/10/2023) during an inshore dive at about 15 meters deep. I mention the precise date because during the canonical 3 minutes of decompression at a depth of 3 meters hanging from the chain of one of the "safe water" signaling buoys, about 200 meters from the rocky and jagged coast, I decide to check the temperature of the water and the computer measured 25°C. ...

Calyx nicaeensis Goblet Sponge

I met this Calyx nicaeensis, Goblet Sponge, during a dive in the reefs of the Secche di Vada near Livorno. The name owes it to its characteristic goblet shape. According to some experts, this sponge has become extremely rare in the Mediterranean because it requires very stable water temperature and biological conditions: small variations are enough to decree its disappearance. We all know by now that climate change has a heavy impact on biological life, but few seem to realize that it also affects the deep sea.

Blue Sponge

Phorbas tenacior, Blue sponge is one of the first organisms to colonize new wrecks or any submerged vertical surface not yet colonized by marine organisms. In this video we see it on a wreck about 30 meters deep. Probably this wreck is quite recent, perhaps sunk between the first and second world wars, has several colonies of sponges including the blue encrusting sponge, which seems to prefer vertical walls away from direct sunlight. Obviously we also see it next to other species of sponges of the genus Tedania and Verongia but if we look at the part of the prow the presence of Phorbas tenacior ...

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.

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.

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.

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.
