Spleen - yes, it was at Shark/Ray Alley. I freaked at first, but the guides didn't seem to think it was a big deal. I got the impression this wasn't the first time they had spotted it. Everytime I watch the video we taped I am like, oh my gosh! Manuel said it was 12ft, but I think it was a little smaller than that, everything in the water looks bigger, but it was big.
