I've never seen a remora yet, that didn't go for the guy's crotch. Haven't quite figured that one out yet. Yes, it does make for lots of giggles, which means flooded mask, over and over again.
But . . speaking of remoras, one day a number of years ago, we dropped down onto the reef (well, OK, not literally ONTO it) and laying there in the sand were two HUGE remora. The moonboot print suckers face up towards us. I'm not kidding, these things were HUGE! I spent quite a while hanging around looking at them . . and not for one moment until years later, did I think . . OMG, what monster were they waiting for to come by?
