These little critters are something I can usually (OK, often anyways) find on our night dive at the manta site up north if the night dive gets longer because the mantas don't show. I have a shot from years ago with my old mx10, but hadn't seen one with any of my digital's in hand. I did a night dive for fun last week and found this one. They're pretty small and often overlooked. I'd like to get a different angle on them some day so you can see the horns more readily.
