Not a jewfish, for sure. It is a Polyprion americanus, known to us as the “Wreckfish”. Worldwide distribution, generally in the deep of the continental shelves.

I used to participate in the Wreckfish fishery on the Blake Plateau off of our Southeast coast.
Did you know Al Pinder and his brothers? They were into spear fishing in Miami and SE Florida. Largest one I saw that that got was around 1,000+#. I had a photo of it hanging from a car wrecker boom. Also same photo, was in the Miami Herald,195x.
