18.59.551N – 112.04.867W. We are diving Roca Partida today, the day is beautiful, the wind is 8kts NW, and 8ft swell NW long period. The boat sits still on the surface, the wind is 72F Today the ocean current runs to the east. The first dive had a very strong current but was super easy on the second dive. The visibility was 100Ft and the water temperature was 75F.
Both corners north and south are the ones with tons of action. The sharks were having a hard time staying in the current side of the rock and they kept circling playing with the current and of course getting cleaned by the barber fish and wrasses. The silver tips, white tip reef sharks, and Galapagos were sharing the place and taking turns to get cleaned.
At a deeper depth, the schooling cotton mouth and horse-eyed jacks were doing the same, playing with the current and getting in a tight ball so the yellowfin tunas would not come to hunt them. They also got two mantas, a black in the north and a chevron in the south. The balconies on the rock were not as full as they would normally be. It looks like the current is a good time for sharks to get in the move and play with it. Nick got a piece of video of a white tip reef shark swimming with its mouth fully open and in the divers’ bubbles, just like the mantas do when they take a bubble bath. Then the shark just went sideways and dived down. Pretty interesting I must say – this could be just a coincidence or is the shark mimicking the mantas.
