Good fight with a nasty attitude and sharp teeth. Some people eat them and I used to when I was a teenager, mostly in Ceviche, but not any more. Although they say that only the big ones have "Ciguatera", in my opinion it's not worth the risk. Yeah, a funny word but it's a neurotoxin which can damage or destroy tissues of the nervous system. It’s the most prevalent marine toxin in the world and it accumulates in the body of fish. There's a rule of thumb here in south Florida that you should throw the fish on the dock and if in a short period of time flies land on it you can eat it. If they don't, it's got ciguatera.
