Need help....what could this be?

Taken in Key largo on the Benwood.

Given it's a a still photo, I can't enlarge it and that there is other blue "material" which appears to the left and below that I identify as sponge, then I would say the object in the circle is also sponge. It has a lifelike appeareance tho. I can't tell much more from the photo. Did it move, have gills or mouth that moved?

Frogfish?

Mutant Gremlin?

I work in a lab that does medical image processing, so I've applied some of our custom software & techniques to analyze your photo. This has revealed the animal that's hiding, which I believe to be oceanus calicus.

You might want to post this in the Name that Critter forum.

Looks like a frog. But if the dark bit on top belongs to him, I'm going with something like a cowfish.


ETA: looking again, the mouth looks too big for a cowfish. Maybe CIC below is right.

It's so difficult to make out. Roughback batfish?

How big was it wildbill?

It was the size of a large fist. I actually did not notice it when I took the picture. My dive buddy was reviewing the pictures we both took and saw it.
