A bullet from the ocean depths, A swimming projectileOde to a Large Tuna in the Market by Pablo NerudaThe Tunny or North Atlantic Bluefin Tuna Thunnus thynnus is by far the largest of five tuna species in the subgenus Thunnus, others being the Southern Bluefin Tuna T. maccoyii, the Pacific Bluefin Tuna T. orientalis, the Bigeye Tuna, T. obesus and the Albacore T. alalunga.It occurs throughout the North Atlantic Ocean and adjacent warm seas, including the Mediterranean in the east and Gulf of Mexico in the west. This highly migratory, surface-living, schooling fish is the only large pelagic fish living permanently in temperate Atlantic waters. Though typically oceanic, it seasonally enters shallower coastal waters (Wheeler, 1978, Collette & Nauen, 1983; http://iss-foundation.org/bluefin/).
