Day 3 of the 3rd Wetpixel whale shark expedition in Isla Mujeres, Mexico: We've had 3 days of whale shark action so far, and each day has given us something different (but spectacular). The first day, a couple hundred whale sharks were spread out in a rather long stretch of the glassy-calm ocean. The water was relatively clear, considering that it was completely full of transparent tunny eggs from the mass-spawning event three nights earlier. Whale sharks gulped down eggs around us from 8am until our boat left (at 1:30pm). On the second day, we discovered a small patch of ocean with hundreds of tightly-packed whale sharks. They were so dense that they were forced to feed in layers, and we saw as many sharks ascending and descending as we did on the surface of the ocean (very rare). Our guides were totally excited, saying that the ocean was infestado with whale sharks. After thirty minutes of total whale-shark insanity, the sharks vanished in a coordinated descent into the depths—it was totally bizarre. One minute, we were surrounded by literally hundreds of sharks, and the next, there were only a few left on the surface. All of us, including the local guides, were totally dumbfounded by the strange behavior.
Today (day 3), we found the sharks 4 miles east and 2 miles south of where they were yesterday. It took a coordinated search effort by multiple boats to find them (which took 3.5 hours on the water), and we weren't in the water until 9:45am. The action was fantastic, with botellas almost literally everywhere we looked (a botella is a stationary whale shark that is vertical in the water, "gulping" water constantly to feed.
I've been shooting with both a Nauticam-housed Canon 7D with Tokina 10-17 fisheye zoom lens, and with a 3D GoPro HERO setup (with Eye of Mine 3D underwater GoPro housing). The 3D GoPro setup has been yielding some very interesting footage because I can get the camera in places where a big housing can never go (e.g. right in front of a whale shark that is cruising at speed). I have some interesting 3D footage that I'd love to present, but two failed upload attempts to YouTube are enough; I'll upload when I return to the States.
In the meantime, here's a 3D screen-grab from the video (red/cyan 3D glasses required):
I also have cute / precious footage of Kieran Liu (the 5-year-old son of my friends Kenny and Lori) swimming madly after a whale shark (and managing to get really, really close). He is fearless!
