I have to make a retraction, I didn't realize there were so many species of batfish. this appears to be a polka dot batfish, indigenous to the Gulf of Mexico (where I found it in the St. Andrews Bay pass).

Hi, Fish and Moubray tested Ogcocephalus radiatus and Ogcocephalus vespertilio for sound production without success (see my summary at: http://www.fishecology.org/soniferous/soundposter.htm

However, they had very limited sampling so their results is not conclusive.

thanks! I put some video with audio up on my drive site if you want to hear it - I talked with some NOAA guys that work in the gulf, apparently they are a known quantity and regularly vocalize in protest to being caught.

HI, you might want to check with Phil Lobel and David Mann, they would be the most likely to have recorded the species.
