Big Eye -or- Bluefin Tuna ?> wtf is the dif?

[Capt. Lou]

The pictured fish appears to be a Bluefin, they r generally somewhat longer in body!
Many believe the only true form of identity in some cases is the serrated liver, BE have this ,BF do not. Also if I recall the finlets along tail BE less ,BF more. Also th eeye itself is somewhat larger than BF, but thats not conclusive!
Im know expert Ive only caught a few of these BE ,I would say 30 0r so at the most but that powerful round body , pure silver at times ,chunky torso with longer pecs usually dead giveaway, uh almost forgot they fight like hell !
generall deeper than BF ,many battles up & down!!
We got em' to 356# SR one time .
Ive personally fought one BE looked to be close to 400# & shattered an early model experimental Graphitr BGR rod after on fish for 2.5 hrs & had him a mere twenty feet from gaff toughtest fight I ever expierenced except for 464 Sword!
Almost all taken at false dawn or just prior most all on troll as I recall & every big girl including record on on a specific lure. Goood chop in the deep was a plus,as was OC days!
