I saw this flatfish in Roatan. He was found on a sandy bottom in about ten feet of water. The locals call it a "lion sole," but it's not in the Reef Fish ID book (although rumour has it the Humann/DeLoach team will be there this week to try and find the critter). Does anyone know its binomial name? Web searches have been unsuccessful for me.
I've seen them a few times here in Roatan too. Around the shop they ID it as a Zebra Sole though I'm not entirely convinced. I saw a really small one yesterday, there's a shot it this blog post.
