Comparative anatomy and systematics of the tunas, genus Thunnus


Comparative anatomy and systematics of the tunas, genus Thunnus



Us Fish Wildlife Serv Fish Bull 66(1): 65-130



The taxonomic status of the tunas of the world, often placed in the genera Thunnus, Germo, Neothunnus, Parathunnus, and Kishinoella, is assessed through the use of external morphological and internal anatomical characters. Seven species, all included in the single genus Thunnus, are considered valid: T. thynnus, the bluefin tuna; T. alalunga, the albacore; T. obesus, the bigeye tuna; and T. albacares, the yellowfin tuna, are circumglobal in distribution; T. atlanticus, the blackfin tuna, and T. tonggol, the longtail tuna, are restricted to the western Atlantic and the Indo-West Pacific, respectively; T. maccoyii, the southern bluefin tuna, is known in the southern Pacific and Indian oceans and off north-western Australia. Two subspecies of T. thynnus are recognized: T. t. thynnus in the Atlantic and T. t. orientalis in the Pacific. In Part 1 the comparative anatomy is described and characters are given for differentiating the species by means of counts and measurements and by comparison of the skeletal, visceral, and vascular systems. In Part 2 the genus Thunnus is characterized with respect to other genera of Scombridae, and for each species a synonymy, a resume of distinctive characters discussion of type specimens and nomen-clatural problems, and a review of known geographic distribution are given.
