Highlights 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 MoreThe Canyon came through with good diving with giant manta rays, white tip reef sharks, juvenile silvertip sharks and a small school of hammerhead sharks. A couple of humpback whales came close by the boat, but weren’t in the mood to interact with the divers.
Read MoreThe giant manta rays were too playful and interactive at the Canyon today. Seriously. Our last dive day turned out to be fabulous, and one of the best days of the trip. The big animal diving at Socorro Island and San Benedicto Island can be wildly variable and while the Canyon was very quiet at the start of this trip, it was smoking hot today. A large school of hammerhead sharks (we estimate at least 100 animals) swam past the cleaning station with 20 or so of the sharks very close to our divers. Some of our divers were only half joking when they surfaced and complained that the overfriendly mantas wouldn’t get out of the way and allow the divers to get unobstructed photos of the hammerhead sharks!
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.
Read MoreVisibility was variable at the outer cleaning station, but we had good sightings of 4 different mantas, schools of tuna, a couple of inquisitive Galapagos and silky sharks, and small schools of scalloped hammerheads as well as 1 possible sighting of a 12 foot long great hammerhead.
