So we stopped in the middle of the Pacific Ocean, turned off the engines and dove into the water for a swim!

The lost ROCK from XDivers Rodrigo Figueiredo on Vimeo.   On our way to Roca Partida we stop to take a swim the weather was so calm and the sun was out. There was nothing much to do but tan on the top deck and just wait patiently to see what Roca Partida had for […]

Giant Mantas and a Whale Shark at Roca Partida

My last dive today was even more special. We were hanging off the north end of Roca Partida in the shallows with 10 or so divers below us and their bubbles streaming to the surface. The positioning of the divers was such that the bubbles looked like vertical curtains with a passageway between them. I was busy admiring this when a giant manta swooped in beside me and flew straight down the alleyway, twisting and turning around the veil of bubbles. It was beautiful. And then he turned around and did the whole thing over again leaving no question in my mind that this intelligent animal was clearly and deliberately playing in the divers’ bubbles.

Silky Sharks Swimming in the Moonlight

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.

Sea of Cortez is Truly Rich in Fish-life and Biomass

Talking about big critters, we did the whale shark snorkeling again and had 5 of them. Everyone saw them. But this time they where not staying and feeding at the surface but resting their tails on the sandy bottom like last time. And in just in 30 feet of water, a young Humpback whale came by!!

Whale Sharks in the Sea of Cortez

We saw five whale sharks at El Mogote and our two local pangas were busy dropping off and picking up our divers. A 6 metre whale shark stopped to feed and positioned itself vertically in the water, completely indifferent to our snorkellers. This provided a great opportunity for photos and videos. Pelicans reportedly dive bombed the bait fish that the whale shark was feeding on and thousands of the fish ended up hiding in the exhaust bubbles from the underwater main engine exhaust of the Nautilus.
