Researchers say they've discovered the first known fully warm-blooded fish.
It's called the Opah, or moonfish, and it lives in cold environments deep below the ocean's surface. Scientists say the Opah generates heat by constantly flapping its pectoral fins. (Video via Science)
It then uses fatty tissue to help trap the heat and special blood vessels to spread the warmth throughout its large, disc-like body.
