We spent the rest of the day at Cabo Pearce where the diving was very good. Divers saw a large school of hammerhead sharks above the outer cleaning station (in approximately 50 feet of water), smaller groups of hammerhead sharks as well as Galapagos and silky sharks.
Read MoreIt’s the last dive day of this trip and everyone is sad that it’s going to be over shortly. The diving conditions at the Canyon and the Boiler dive sites at San Benedicto Island can be highly variable and Captain Dave reports that the diving has been quieter than usual over the last couple of weeks. It’s still “very good” with large biomasses of fish, silvertip, Galapagos, silky and hammerhead sharks and, of course, our friendly giant manta rays.
Read MoreJust to top things off, four giant manta rays came into to the rock and spent “quality time” with our divers, gliding by close enough to touch. Interestingly, there were very few silky sharks, and divemasters Sten, Tricia and A.J. speculate that the silkies may have been intimidated by all the other sharks. Diving the Revillagigedos (Socorro Island) is not always hot but man, when it’s on, it is RED HOT DIVING!!
Read MoreThe outer cleaning station (one of our favourite dives at Socorro Island, first recommended to us by cinematographer Bob Cranston) had very good dive conditions with calm seas and mild current, five scalloped hammerhead sharks and one Galapagos shark. One giant manta ray cruising by didn’t seem interested in interacting with the divers. And, of course, the ever-present silky sharks shadowed the divers, curious but not aggressive.
Read MoreHighlights included a huge bait ball of skipjacks being hunted by silky sharks and 100-pound yellowfin tuna, a group of five hammerhead sharks that approached within 40 feet of the divers and a blue water drift dive looking for pelagics. All the usual Roca Partida critters were present, including over 30 white tip reef sharks, silky and Galapagos sharks and some curious wahoo.
Read MoreDivers saw the usual complement of electric rays, Socorro lobster, silky, Galapagos and hammerhead sharks, but their most spectacular encounter was with a single bottlenose dolphin who adopted the divers. We’ve been seeing similar behaviour from the dolphins all winter, where they hang out and literally imitate the divers. If a diver hangs on to the ascent line, the dolphin will rest the underside of his head on the line. If a diver blows bubbles, the dolphins will blow bubbles. If a diver does a 360-degree roll, the dolphin will do a full roll (well actually, they tend to be somewhat playful and will often do a 720-degree roll or even a triple barrel roll).
Read MoreInterestingly, one group of divers reported observing behaviour that reminded me very much of the great white sharks of Guadalupe Island. Last season we would see 2 white sharks swim side-by-side as if they were measuring their respective lengths against each other. The smaller animal would then peel off into the blue. The larger animal presumably being the dominant animal. I “think” we saw the same thing with 2 giant manta rays. 2 animals (a chevron manta and a larger black manta) swam in tight formation in a vertical pattern. The smaller chevron then peeled off and disappeared into the blue. Presumably, just like the white sharks, the large black manta ray established it’s dominance and got to hang out with a human.
