Schooling juvenile silvertip sharks

Captain Dave reports that on their first morning dive at El Canyon at San Benedicto Island, divers saw two hammerhead sharks swimming alongside a school of silvertip sharks. Some of the Silvertips were very small, measuring less than 2.5ft. Meanwhile, one of the hammerheads was huge for a scalloped hammerhead – an estimated 12 feet!

Amazingly loud humpback whale song

Captain Dave reports that humpback whales were singing so loudly today that guests could hear the song inside the lower deck staterooms on the Nautilus Explorer!!! It was quite something for our guests while on their dive. In-water visibility was down on the east side of Socorro Island, with lots of phytoplankton in the water column. While this made it hard to spot big pelagic animals off the outer cleaning station at Cabo Pearce, the guests were rewarded with a great show of feeding behaviour by the giant manta rays.

Fabulous day of diving with giant manta rays at San Benedicto Island

The 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!
