Researchers discover world's first warm-blooded fish
Scientists at the National Oceanic and Atmospheric Administration have discovered the world’s first warm-blooded fish – the opah.
Researchers discovered that the fish circulates heated blood through its body much like mammals and birds by constantly flapping its fins to move around. The fish is able to flap its winglike pectoral fins to move forward, unlike most fish. Its pectoral muscle is insulated from the cold water by a layer of fat.
