Recently, the Spanish Ministry of the Environment and Rural and Marine Environment [Ministerio de Medio Ambiente, Medio Rural y Marino (MARM)] has approved, through a positive environmental impact declaration, the surveying of a large marine area in the search for fossil fuels, that could be found at more than 1600 metres, on the sea floor at a depth of 200 metres.

Today we have navigated towards a new submerged elevation, to see what we could find in its depths.  We are referring to Algarrobo bank (it is the name given to some kinds of marine elevations) submerged in front of Malaga, approximately 20 nautical miles from the Spanish coast. When we left the port of Almerimar, with a few hours of navigation ahead, some of us thought: “good sea today to see cetaceans”.  The sea was like a plate and the sky, although it was a bit cloudy, was not going to stop the spectacle we would witness:

This time, the surprise has come by the hand of a mollusk, the giant oyster Neopycnodonte zibrowii. More than 400 metres in depth, over some rocks, we have found several individuals of this long-lived animal, who lives up to 500 years and is considered a living fossil.

This time, we saw two groups of at least 15 individuals, something similar to what we were able to observe in 2010 while we were working in the same area.

We start the day with a dive off Punta de Baños, a place also known as "Culo de perro." The seamount is pretty interesting because its southern slope rises two or three meters from the sea bed, harboring numerous gorgonians Leptogorgia sasarmentosa and many other species we'll describe when we analyze the images taken by the divers.
