1.b. Dorsal fins not widely separated - go to 2
2.a. Pectoral fins long (extend past the end of the first dorsal fin) - go to 3
2.b. Pectoral fins short (do not extend to the end of the first dorsal fin) - go to 5
3.a. Pectoral fins very long (extend past second dorsal fin) and are dark in color - Albacore (Thunnus alalunga) (137 cm / 54 in) - primary species
3.b. Pectoral fins do not extend past second dorsal fin and are yellow in color - go to 4
4.a. Second dorsal and anal fins elongate in adults. No striations (lines) on underside of liver - Yellowfin Tuna (Thunnus albacares) (1.9 m / 6.5 ft) - rare species
4.b. Second dorsal and anal are not elongate. Striations (lines) on underside of liver - Bigeye Tuna (Thunnus obesus) (2.4 m / 8 ft) - rare species
5.a. No dark stripes on body. White dots in lines on belly and up sides - Bluefin Tuna (Thunnus thynnus) (1.9 m / 6 ft) - rare species
5.b. Dark stripes along body. No white dots in lines - go to 6

Those little guys aren't as tasty as slightly larger models in the 50lb+ range, less fat content/flavour. Not really any belly cut or any chance of collars to grill up (kama)
