We started the day sounding the canyon near the Castro Verde seamount to later sail toward the coastal area between Punta El Mariano and Punta la Code (between Islares and Castro Urdiales) where divers went on a shallow dive (between 6 and 15 meters deep).
The rocky bottom with slight unevenness was covered by seaweed of the genera Cystoseira, Dictiota, Gelidium, Falkengergia and some incrustations of red seaweed. In some areas, the rock was covered by sea urchins Paracentrotus luvidus. This area is well known because during the dives, it is usually easy to see skates, but in our case, we did not find any. On the other hand, we found schools of bogue (Boops boops), cuckoo wrasse (Labrus bimaculatus) and greater pipefish (Syngnathus sp.).
After the dive we returned to Getxo, where we had dinner with Juanjo and Ana Leiva, director of Fundación Biodiversidad.
