Cochlear ostrea - Neopycnodonte cochlear
Ostrea Neopycnodonte cochlear is a species of marine bivalve molluscs belonging to the family Gryphaeidae. This species have been recorded as fossils from the Miocene to the Quaternary (from 15.97 to 0.012 Ma). Shells of Neopycnodonte cochlear can reach a size of about 27–120 millimetres (1.1–4.7 in). Shells are usually brownish or purplish, quite thin, without prominent ribs. The lower valve is rounded, the upper valve is smaller. ostrica neopycnodonte cochlear
This species can be found in the North Atlantic Ocean (Azores) and in the Mediterranean Sea. The peculiarity we want to point out is that it is a small oyster that plays the same role as corals. That is, it forms aggregations as they grow and multiply, create agglomerations of more or less large dimensions comparable to corals. The video clearly shows these aggregations, ranging in color from white to brownish yellow, which formed at a depth of 70 meters.
This video was shot during a scuba dive in the area between Livorno and Gorgona Island. We are over 12 nautical miles from Livorno and about 6 miles from Gorgona island. In this area the seabed rises from over 100 meters deep to 48 metres. It is an area that we know well in the part between 48 and 54 meters deep, but the sea always reserves unexpected surprises: in fact from the echo sounder we saw that there are reef at depths of 60, 70 meters and more. The interesting thing is that these deep rocks have never been visited by divers and therefore we are the first to document the beauty of these seabeds.
However, to be able to document the seabed with the camera it is necessary to have good lighting because the sun’s rays arrive very weakly and the colors of the seabed tend to be uniform grey; the lights instead allow our camera to highlight the entire range of colors present in the coral reef.
