I've ben meaning to post this for a long time----finally remembered. Every time I'm on a long trip to Hurricane Bank/Buffer zone we'll catch some of these off the bottom. Almost everyone on board calls them threadfin sculpin, but they aren't sculpin (Cottidae) at all, but actually a scorpion fish; Spotback scorpionfish to be exact (Pontinus vaughani) in the family Scorpaenidae. They're related to rockfish. Anyway, this is just an FYI because it comes up on every trip and I thought I'd just put the information out there.
