Total number of species: 15

Tuna are the sea’s mightiest swimmers and one of its most agile predators. With a sleek, streamlined, torpedo-shaped body built for speed, this pelagic species can reach speeds up to 75 km/h (45 mph). Unfortunately, however, this speed is no match for the commercial fishing that threatens some of their populations. As a result of overfishing, tuna fish species like the southern bluefin tuna are nearing extinction.
