We consider Roca Partida to be the crown jewel of diving Socorro/Revillaigedos but by the very nature of Big Animal diving, it’s not always going to be super hot. Current scientific thinking is that the local population of giant manta rays actually traverse a 1200 km route that takes them by San Benedicto Island, Socorro Island, Roca Partida and then up and across to the west side of Baja California before looping south again.
Read MoreDivemaster Sten (affectionately known as Vikingo) reports that the warmup dives at the divesite El Canyon at San Benedicto Island were pretty quiet without much life. Sten and Captain Dave decided to move around to the tiny submerged pinnacle on the west side of San Benedicto known as The Boiler and found that the diving was on fire with 3 black mantas, a dolphin and even a hammerhead shark coming in to check out our divers.
Read MoreWe’ve been watching one poor old Galapagos shark with a fish hook and leader stuck in his gill plate all season. I’ve become quite certain that Galapagos sharks are resident rather than transient because we see this guy every time we dive Roca Partida. The sad thing is that he has been getting skinnier and skinnier and now looks quite emaciated. The alarming thing is that his behaviour is changing and he is now coming in VERY close to divers. He swam up to me this afternoon and it’s the first time that I had a gut feeling that I had better “watch out” around him. An understandable behaviour I guess if he is sick and starving to death. Damn, I wish there was an easy way to get rid of the illegal longliner fishing boats.
Read MoreDave reports that the divers saw 7 silver tip sharks between 5 and 7 feet in length circling at the north end of Roca Partida, along with at least 10 silky sharks and some good-sized Galapagos and hammerhead sharks. One interesting note is that one small silvertip shark apparently chased away 4 larger silky sharks (4 – 5 feet in length) that were hanging around a tag line hanging off the back of the Nautilus Explorer. Not sure on the dominance behaviour of silky and silvertip sharks, but that strikes me as highly irregular behaviour.
