Seen while snorkeling around Grenada, Caribbean... what is it? Have looked through numerous guides and can't find it... about 7 inchs long, with a mouth like a grouper and big eyes. Feisty.
The picture is rather small even when clicked on, can you please make it a little larger? It would help to see some more details. The head coloration and general shape look a lot like a Hairy Blenny to me (a blenny that can well reach 7 in.) But can't tell from this pic if it has cirri or not, and can't tell if it has a dark spot on the gill, although this feature may be obscure.
I didn't find anything close in the Sea Bass, Grouper family, but I'm only working with the H/D guides.
Hairy Blenny
Looks like you have found a Hairy Blenny, Labrisomus nuchipinnis.
Ah, beat me to it!
Looks like Louis and I were typing at the same time... but I'm happy to see came to the same conclusion :)
Hard to tell
