con Posidonia Dive
Nudis and Posidonia! Barracuda schools circled us at dive end
Anchorage at 15-16m on the western side of the easternmost ridge - this site has two parallel ridges, with sandy bottom and healthy Posidonia fields in between and around the ridges, which are more flat than in typical Maresme sites. We started the dive towards north, observing various pink flatworms and one Cratera peregrina on the rocks. Northeast direction slowly descends towards 20m - we kept on following the border of posidonia/sand and the flat ridge. Schools of castañuelas all around and Mediterranean wrasses and red start fish hiding in the posidonia - one small morena below the rocks. The two parallel ridges come close and unify towards the northeast - from where we continued towards the eastern side before turning back with approximately 150 bars - really relaxing dive with no current at all. It's not 100% trivial site to navigate; coming back you might take the eastern ridge and miss the boat - not sure if they spread the line across both, likely not. Nice smallish langosta posing for the camera on the sand next to his hiding place and another morena curiously finding refuge behind on the posidonia field. Medium sized brown wrasse (Labrus merula, Merlo) feeding somthing in the posidonia, oblivious on me observing him. Coming back to anchor we still had 100 bars left so macro photo time, and as typical for winter times, there was plenty on the top parts - pink flatworms, another Cratera peregrina, two pairs of vaquita suizas. But the best perhaps came at the end when fearless schools of barracudas visited and circled us near and between the divers. Back in the boat somebody told that one previous local dive center had great idea of submerging their old tanks as refugee for octopus and likes, and there is congregation of the tanks somewhere - I recalled actually seeing one. Also other diver has seen a ray on the sandy bottom, but did not ask which species.
