Found this guy at night in Cozumel. I was thinking it was a lesser electric ray but the shape of the head especially the back doesn't seem to match. The eyes don't seem right either. I am sure I am off with this ID so any help would be greatly appreciated. I have the book Reef Fish Identification by Paul Humann and Ned Deloach as well as a couple other field guides and have done internet searches. Any advice on good identification websites or apps is also appreciated.
