Location: Punta Tosca, Cabo Pearse, Socorro Island, Revillagigedos, Mexico
Comments: After checking in with the Mexican navy on Socorro Island, we headed over to Cabo Pearse for three dives and night snorkelling with the Silky Sharks. The visibility was 30-50 feet depending on which part of the dive you were at and the current was minimal. Unfortunately, the lack of current meant that there were not many large critters out there. Many guests were able to listen and enjoy hearing the humpback whales singing during the dives. We saw the Clarion Damselfish which is endemic to the Revillagigedo Archipelago but once again there was a sense of disappointment in the diving. That night, however, the Silkys were abundant and all who wished to were able to get in and snorkel with them until the mood changed and the sharks started hunting more earnestly, at which point everyone got out.
Punta Tosca on dive day 4 was also surprisingly quiet and the visibility was low so after 2 dives at the outer point we decided to move the Nautilus up a couple of bays and try a new site. A series of small rocks sticking out of the water with a sheer drop to 120 feet on one side and shallower bays on the other. It proved to be fascinating and several guests saw sea turtles and a “fly by” with a giant manta. Definitely a site that we will repeat but once again the “charismatic megafauna” was elusive. So now it was off to Roca Partida to see what was going on there.
