Thanks for the kind comments, some of you may be interested in another video I took at the Galapagos, called 'Flight'; you should see the link to it at the end of the 'Galapagos' video, with a thumbnail of a pelican taking off. I don't think it'll be appropriate to post the link here as it was shot entirely with a Sony FS700 at 480 fps, although I did use it with a Canon 300mm F4 + 2X Teleconverter.
I am mostly a still photographer but when you get to go to places like the Galapagos Islands with such amazing creatures, it's more interesting to take videos I think. Most cameras nowadays can capture HD and the 5D Mk lll is particularly great in doing capturing in HD, the only downside is that it can only do up to 60 fps. If you're going to take videos with a DSLR, I recommend you get some kind of LCD view finder which magnifies as it'll be hard to do manual focusing with the existing LCD screen; and some kind of mini movie rig or a monopod as you'd have to move your camera around very quickly.
If you are into snorkeling and diving you'll be in for a treat as there are some amazing creatures under water too. The first time I got into the sea there I found myself surrounded by hundreds of sharks, literally, and there was a 15ft+ hammer head shark right under me (which I thought was a submarine at first), it was both super scary and exciting! Pity that I didn't have any good underwater photography equipment, otherwise I would have gotten myself some great memorabilia.
I didn't go to Guayaquil, the only other places I went to in Ecuador was Quito, beautiful city with beautiful churches and the Santa Lucia Cloud Forest, which is a photographer's heaven, highly recommended.
