Giant bluefin tuna life expectancies

The average natural lifespan of bluefin tunas is 15-30 years. Atlantic bluefins are homeothermic (“warm-blooded”) and are therefore able to thermoregulate keeping their body temperatures higher than the surrounding water, which is why they are so well adapted to colder waters.
