The Life of Animals | Bluefin tuna | The bluefin tuna is one of the largest, fastest and most beautiful colors of all fish in the world. Their torpedo-shaped bodies are agile built for speed and endurance. Bluefin tuna are warm-blooded, a rare trait among fish, and are in the cold waters of Newfoundland and Iceland, as well as the tropical waters of the Gulf of Mexico and the Mediterranean Sea where they spawn easily go to every year. You can retract their dorsal and pectoral fins into slots to reduce drag. And some scientists think that the series of "finlets" on their tails may even serve to reduce water turbulence.
