I literally laid on the white sand bottom at 175 feet watching 12 leather bass (yes, I counted them!) and a school of big eye jacks swarming around me, the bizarre free swimming fine spotted moray eels of Clipperton Island swimming around like fish everywhere I looked, beautiful brilliant blue juvenile endemic Clipperton angelfish darting around and the coral wall sloping up above me with the Nautilus Explorer outlined up above in the beautiful blue water.
Read MoreI have to report that we haven’t seen many sharks yet. Three hammerheads and a couple of silvertips today and that was it – OH WAIT!! We also saw a nice 25ft whale shark swim by this morning!! We often see whale sharks at Roca Partida (Socorro Island) in November and December, and then they disappear when the water cools down as the cool waters of the California current push southward. The water temperature at Clipperton Island is presently 82˚F and I’m wondering whether the Socorro whale sharks head down this way to stay in nice balmy water?? Hmmm.
Read MoreWe checked the radar and discovered a large (225ft??) target doing tight circles off Roca Partida and clearly in the Biosphere Reserve. I suspected that it was a large tuna clipper and that they were watching us through their binoculars because as soon as we launched one of our inflatables, all the lights on the other ship blinked off. The illegal boat then started jinking around at high speed (15 knots plus), apparently doing it’s best to stay away from the inflatable.
Read MoreOne of our divers reported seeing extraordinary behaviour with a very large male mobula ray (which is still dwarflike in size compared to a giant manta ray) pursuing a female chevron giant manta. While we have seen a lot more female than male mantas this season, the males are definitely here and we sometimes observe what appears to be mating behaviour with the male pursuing the female from behind and the two of them soaring and dancing through the water. It’s hard to tell if they are both enjoying it (not meaning to anthropomorphize the behaviour too much) or if the female is simply trying to get away from a doggedly determined lustful male!! Anyways, Roberto is quite sure that the pursuing ray was a mobula as its mouth was not located terminally. Soooooo, the question is whether he might have witnessed a prelude to interspecies sex!?!
Read MoreSo there we were, towards the end of our dive, coming around the north end of Roca Partida and swimming through an enormous school of jacks when, HOLY COW, a group of very large Galapagos sharks swam right up to us and started circling around. I had never seen anything like it.
Read MoreAnyways, the visibility this morning 80ft plus and our divers had some great hammerhead, silvertip and galapagos shark sightings. Plus good old Lumpy, our tame leather bass with the broken jaw was there as always. I was very tempted to stay for another dive but flexibility is the name of this game and our guests wanted to move on to the Boiler on the west side of San Benedicto Island.
Read MoreA group of guests also went out in a skiff to get a closer look at four adult humpback whales and one juvenile and were rewarded with 15 minutes of dramatic tail lobs (smacking their tails on the ocean surface). While tail lobs can be a “back off” message directed at humans, or a “let’s get together guys and stay close,” it seemed much more likely that there was some male to male competitive behaviour going on here. ‘Tis the season at Socorro Island for humpback whales to mate and breed!!
