On-board Diary: Bahía de Santander. Isla de la Torre

After two days waiting in Santander without having been able to dive at all, everyone on board is anxious to dive and document the sea bottom. However, working conditions outside the bay continue to be unsuitable.

Pablo López invites us to go diving with him at Isla de la Torre, an area strongly influenced by tidal currents. In spite of poor visibility, we are surprised by the seabed's great biodiversity. At a depth of just 5 and 8 meters, above a rocky substratum, Kike Talledo used the dive as an opportunity to photograph the abundance of nudibranchs belonging to 7 different species. We found numerous spots were these mollusks were found, mainly the species Flabellina affinis and Dondice banyulensis, two species that are difficult to find elsewhere.

Of note is the presence of the sea squirt Aplidium proliferum. This was the first time that we found them since we started the expedition.

During the dive, we also came across a school of triggerfish (Balistes carolinensis).
