Pelagic fish Atlantic Ocean, the Gulf of Mexico and the Mediterranean Sea. The term highly migratory species (HMS) is a legal term which has its origins in Article 64 of the United Nations Convention on the Law of the Sea (UNCLOS). The highly migratory species include: tuna and tuna-like species (albacore, Atlantic bluefin, bigeye tuna, skipjack, yellowfin, blackfin, little tunny, Pacific bluefin, southern bluefin and bullet), pomfret, marlin, sailfish, swordfish, saury and oceangoing sharks, dolphins and other cetaceans. Essentially, highly migratory species coincide with the larger of the "large pelagic fish", discussed in the previous section, if cetaceans are added and some
USS Skipjack (SSN-585) and appendage drag can be combined via algebra to show that the vessel should have reached 31 knots submerged. This speed was some 9 knots faster than the "Nautilus" made using the same basic reactor, and only 2 knots shy of the "Albacore"'s best theoretical submerged speed (33 kn). "Skipjack"'s maneuver capabilities, furthermore, added a whole different dimension to ASW problems as she could reverse direction in the distance of her own length, and were referred to as "flying", as "Skipjack" and her sister ships climbed, dove, and banked like an airplane. The antisubmarine warfare (ASW) problems created by such
