This strange fish has boggled my diving friends and I. We were diving in the Bahamas (Nassau) at the site Willaurie. It was found under the wreck "sitting" stationary, even when I swam right up to it. It was dark grey with a big black eye. It was about 14" long. It looked like it had an "arm" instead of a pectoral fin that held it steady.
Please help in identifying it!
