Humpback Whale and Calf Sharing a Safety Stop with Scuba Divers

By on February 20th, 2008 in Archive

The visibility and surface conditions were excellent today, and the sharks were very cooperative, with multiple sightings of silvertip, silky, Galapagos, hammerhead, and of course whitetip reef sharks. And at the end of the second dive, a very lucky group of 5 scuba divers saw a female humpback with a calf swim by at their safety stop! This is an extremely lucky experience, and I think I can speak for the group who saw this when I say that it made their trip and won’t be soon forgotten.

Zen-Like Bluewater Diving Looking for Mantas and Sharks

By on February 11th, 2008 in Archive

Silky, Galapagos, and hammerhead sharks made numerous appearances, along with large schools of yellowfin tuna, almaco jacks, trevally, and the innumerable triggerfish and reef animals that we’ve come to expect.

Tuna, Hammerhead and Silvertip Sharks Galore but Where’s the Giant Mantas???

By on February 2nd, 2008 in Archive

There was a coldwater current running past the island steadily for the whole two days, and with it came excellent visibility and a great amount of hammerhead, silky, Galapagos, whitetip, and silvertip sharks.  That’s on top of the friendly wahoo, the massive schools of tuna, the unique photographing opportunity of a moray eel wrapped comfortably around resting whitetip sharks, and big schools of triggerfish, big-eyed trevally, jacks, and other familiar faces.

Cooler Water, More Shark Encounters and the Possibility of Whales

By on January 11th, 2008 in Archive

The upside of this cooling is that the larger oceanic sharks start appearing. We saw a group of 6 silvertip sharks and 4 galapagos sharks patrolling “fish alley” where the large schools of jacks and bonitos hang out. There seems to be a hierarchy in the shark world whereby silkys are displaced by galapagos which in turn are displaced by silvertips.

Silky Sharks Swimming in the Moonlight

By on November 29th, 2007 in Archive, Socorro

Two whale sharks. One was the size of a bus! 45 – 50 feet long and a little brother of maybe 21 feet. We also got visitedby giant manta rays. It was a good start and we had the whale sharks around the rock for the rest of the day. We also saw whitetip reef sharks of course but just a few Galapagos and silvertip sharks – likely because of the relatively warm water?! A good day. At night with no moon we were surrounded by about a 50 silky sharks chasing flying fish in the floodlights of the Nautilus Explorer.

Scooter diver buzzed by a Giant Manta Ray

We’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.

Shark sightings and spawinging urchins at Clipperton Island

By on April 17th, 2007 in Archive, Captain Mike

Far and away the coolest thing we saw on our afternoon dives were spawning sea urchins! Yup, we happened across in-water sexual reproduction as the urchins released sperm into the water column. It looked almost as if the urchins were sending up smoke signals with puffs of white “smoke” (sperm) spiraling up from the top of these amazing echinaderms. You have to think that it is a very long shot that eggs are going to get fertilized this way but that’s what happens.
