There you go - if that post title doesn't work for a band name or some murder mystery novel, I don't know what would... ;)

Anyway, our second to last dive on our most recent trip was at a site called "The Lost Blue Hole". A blue hole is basically an underwater sinkhole, and is so named because from above they appear a deep dark blue color when compared to the shallow light blue color of the reef and sand around them.

This photo really doesn't do justice to this blue hole, but does kind of give the idea of what it is like to dive into one - to some extent, it felt like diving off a cliff.

Even at its widest zoom, my 18-55mm lens couldn't even begin to capture what the opening of this blue hole looked like.

As we went down into the hole, there were many ledges and shelves where various fish and other critters were taking up residence. On one large shelf, there was an enormous sea turtle with two incredibly large remoras attached to it...

There were also plenty of lionfish at this dive site (notice the big one in the right side of the frame).

Since the day was pretty overcast, it was fairly dark down in the blue hole, so Anya and I didn't linger for long. After a few minutes, we went back to the opening to explore the sand and small patch reefs surrounding the blue hole. As we came up, Anya pointed out a medium sized Southern Stingray swimming by us. I quickly framed my shot and rattled off some photos as I gently swam along next to it.

Look closely and see if you can spot the second, much larger stingray hiding right in front of your eyes! I honestly didn't see it the first time by, and I'm glad I wasn't swimming directly over top of it as that could have spooked it and could have been a bad situation.

We also saw a small group of Nurse Sharks, some of which were displaying flashing behavior where they give a quick tail flick while turning and rubbing their sides against the ground or some other rough surface - usually to try and rid themselves of parasites, or just to scratch an itch.

By this time, I did notice the extra large stingray still hiding itself in the sand. I approached it slowly from the front and managed to get a nice portrait...

While the conditions weren't great for photography because of the overcast morning, this was still an interesting dive, and a good reminder to keep my eyes open and look for hidden critters everywhere!
