Wow, the Sandtiger is great, Louisianadiver!
I like also those two nudibranchs, Larry and Grateful Diver!
And about the moray, hmmm, I think I prefer the first picture, it's a mouth that belongs to the realm of nightmares, you can imagine practically everything coming out behind those teeth!! The picture is overhelming!
And now mine. I try to acomplish (indeed some didn't

) the conditions Alcina set, and that's to select only one picture. It's difficult, it's a work to be done alone (don't let anyone give his opinion, cause they will always choose a different picture than the one you were thinking of), but just that, the work to find one unique picture makes it a real challenge.
It's in Ustica, Sicily, an example that even the Mediterranean has somtimes great underwater visibility. Hope you enjoy it!
