Atlantic Bluefin Tuna – 43 mph

The Atlantic Bluefin Tuna is a unique fish because it has a warm blood supply. Warm-bloodedness is a trait shared by all tuna species, but the bluefins is particularly effective. Atlantic bluefins are native to the Mediterranean Sea, the western and eastern Atlantic Oceans, and both. In the Black Sea, they have vanished. The Pacific bluefin tuna and the southern bluefin tuna, the other two species of bluefin tuna, are closely related to the Atlantic bluefin tuna. The fish's speed can undoubtedly be attributed to this, among other things. 43 miles per hour has been recorded for the bluefin.

Although the longest bluefin was 12 feet long and about 1500 pounds in weight, they can grow to be between 6.6 and 8.2 feet long and weigh between 496 and 551 pounds. It is a strong fish that can battle for days and have a lifespan of 50 years. A bluefin tuna female can lay 30 million eggs at once. Still, this fecundity hasn’t made up for the fact that the bluefin has been overfished and is now endangered globally.
