When the Moon hits-a you eye like a big pizza pie...
That's a Moray!
*snort* Okay, seriously if you remember anything about THE DEEP other than Jacqueline Bisset's T-Shirt, it was actually a decent little thriller with a good cast. And it had a slick monster in the big Moray that came lunging out to lock its jaws on you. The scene where Jackie pokes around in a hole with a stick, gets abruptly yanked around violently and then breaks loose... and leaves the stick behind, all chewed up? One of the better fright moments in a non-horror movie, I submit.
