Pectoral fins very long, saber-shaped, their length in the adult about f 

 the length of the body. Otherwise essentially as in Thunnus, to which 

 the genus is very closely related. Size large, but much less than that of 

 the species of Thunnus, (German, the French name of the long-finned 

 Albacore.*) 



*Albacore is from Albacora, a Portuguese name said to bo from the Arabic al a, and bacora, 

 little pig. It should not be spelled Albicore, as it is not connected with albus, white.
