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.

Diving among gorgonians II

Diving in this reef completely covered with branches of red Gorgonia up to two meters high is always fascinating. Despite the poor visibility our torches manage to bring out all the colors of the underwater world. They range from the scarlet red of the Paramuricea clavata, to the yellow of the countless sponges and the arazoanthus axinellae, the sea daisy, to the red of the Corallium rubrum and the red scorpionfish. The pale pink ...

Biodiversity

We are on an isolated patch of rock and coralligenous about 7.5 miles from the coast; the seabed varies from 49 to 52 meters, the area to explore has a surface area of ​​about a couple of basketball courts (about 600 square meters X 2). All around a sea of ​​mud and a mixture of mud/sand separates us from the main submerged reef 400/500 meters away, always on the bathymetric of 50 meters. ...

Sustainable fishing Red gorgonia

In the video you can see a branch of red Gorgonia, Paramuricea clavata, measuring over a meter in length, torn a few days ago from the reef where it was located, lying dying on the muddy seabed. This species and these corals when they manage to reach such dimensions are about a hundred years old. Collecting the coral from the seabed you can still see open and therefore alive polyps.

Colours of the Mediterranean Sea

Deep sea has an intense blue color. The light that penetrates the water changes its light intensity and its spectral composition by effect of  selective absorption by water of the different wavelengths that make up the visible spectrum. The ultraviolet and infrared stop the first few centimeters of depth, then extinguished the red, orange, yellow, green and purple and blue that reaches greater depths. ...

Giant triton

Meeting Giant triton - Charonia tritonis - always arouses a strong emotion, both because it is the largest mollusk in the Mediterranean Sea and because it is increasingly rare. Fortunately here on intotheblue.it we have published several videos of this splendid shell so despite all the alarms we give about the health of our sea, when we encounter the Triton the hope that the sea can really regenerate itself returns to be present. ...

Paramuricea clavata - Red gorgonian - Reproduction

In this dive of August 15, 2023 we filmed an event that has not yet been documented much in our Mediterranean Sea. This is the reproduction of the red Gorgonian (Paramuricea clavata). Like every year in summer, this beautiful coral reproduces with the synchronized emission of male and female gametes released by the polyps which open by extruding thin semi-transparent filaments exceptionally long up to 5 cm. ...

Red scorpionfish

In this beautiful dive we met many specimens of Red scorpionfish, Scorpaena scrofa, and these that we see in the video are particularly large, almost a meter long. This species is typical of the Mediterranean Sea and we have met them at a depth of 52/53 meters in what would be their ideal habitat, i.e. the typical coralline seabed full of holes and ravines where Gorgonians and sponges thrive on which they settle perch waiting to launch some ambush to fish like the red damselfish.

Mimicry

One of the things that often happens during a dive is to pass in front of some fish and some organisms without seeing them. In this case, this is exactly what happened, fortunately being a couple and having the opportunity to review ...

Red algae on Violescente Sea-whip

The video that I present to you shows a Red Alga that has parasitized a Soft Coral (Paramuricea clavata). Parasitism and mutualism, or symbiosis, are very frequent phenomena in the marine world between similar species and different species. ...
