That bull shark looks fat.
According to our dive guide, he thought it was a pregnant female (although I guess that's a little redundant). On the same dive, we also encountered two or three (was hard to tell with the viz) adolescents and three or four juveniles. The juveniles, I guess being more curious, were the one's that got closest to us during the dive.
Well worth the effort to get out there, would do it again in a heartbeat. I highly recommend this destination.
