On our way out to the dive site, we ran into three frolicking whales.
Soon, I was in the water, on the brink of hyper-ventilation.
Unfortunately, I found out after buying my underwater disposable camera that the disposables won't work more than about 10 ft. below, so I was unable to get any of the deep stuff.
While we were down there I got to touch a pufferfish, which puffed up until it was more like a baseball than a fish. It was quite amusing watching it try to swim away with its new body shape.
