Pacific bluefin tuna, Thunnus orientalis are some of the biggest and fastest fish in the Pacific Ocean. The tuna possesses a streamlined body to reduce water resistance and conserve energy for trans-Pacific migrations. Retractable fins also allow a freer flow of water when navigational changes do not require their use.
