History
"The tuna is most commonly known as a food fish.\n \nThe tuna has a sleek, streamlined body that tapers to a narrow junction at the tail. It is built for sustained speed, with strong pectoral fins that fold into grooves against the body, and eyes that lie flush with the body surface. At full speed, the tuna has been recorded reaching speeds of up to 46 mph. A wide, forked tail propels it through the water. On each side of the tail base are bony keels that are extensions of the caudal vertebrae. A special vascular system below the skin helps keep the fish’s body temperature higher than that of the water in which it’s swimming, increasing its output of the muscles and accelerating nerve impulses. This allows the tuna to exist in colder regions.\n \nTuna is most sought after as a food fish. Its flesh is pink to dark red, different from the white flesh of most fish.
