Researchers have recently discovered the first warm blooded fish- the Opah or moonfish. This large fish with small fins moves surprisingly fast and it can also flap its fins, much like a bird. It also hunts slow-moving cold blooded sea animals. Scientists from the National Oceanic and Atmospheric Administration (NOAA) Fisheries’ Southwest Fisheries Science Center in La Jolla, California stated that they have never seen anything like this before. It is also strange that the opah can keep itself warm even in very deep ocean waters of at least 150 feet below sea surface.
