The Opah (Lampris regius) is an unusual game fish found mostly in tropical and temperate waters around the world.

It’s also a known carnivore that mainly preys on smaller fishes, squids, and crustaceans.
The most unusual thing about this fish is that it’s the only “true” warm-blooded fish species—meaning, it’s the only fish that can regulate its own body temperature. Yes, some fish species like tunas, marlins, and some sharks can temporarily make specific parts of their bodies warm, but only the Opah can warm its entire body. So even if it can still hunt for food in cold waters, it still has to return to the surface regularly to warm their heart, brain, and other vital organs.
