Tuna
High-Efficiency Robotic Fish Propulsion
Tuna are built for sustained speed. Bluefin tuna cross entire ocean basins on their migrations. Skipjack, yellowfin and albacore tuna swim constantly; many species must keep moving to force water over their gills. Their bodies show the engineering of endurance: a streamlined, rigid torpedo shape; fins that fold into grooves; a narrow tail stalk with keels; and a tall, crescent-shaped tail that beats quickly and efficiently. Unusually among fish, many tuna keep their swimming muscles warmer than the surrounding water, boosting muscle performance.
