Dolphinfish (Mahi Mahi) is more like swordfish, at least in flavor. It is not a species of actual dolphin. It is not warm-blooded. Dolphins, including the killer whale, are warm-blooded.
Well, many types of true bony fish (osteichthyes) are also warm blooded. Tuna comes to mind.
Older concept that only mammals and birds are warm blooded is incorrect. Endothermy is apparently not only a survival advantage under many circumstances, but are relatively easy to evolve. So many other animals we would not classify as mammal and birds, including many highly active pelagic fish, have also been found to have independently evolved endothermy.
