This 450 pound black marlin was caught off Cairns, Australia. After about 22 minutes it panicks and goes down deep, where the sharks live. Big mistake. At least we got to keep the Bill! As for the size, its the Captain who makes the call, not me. Barry Cross (skip) estimated it to be around 450lbs, so thats what i go with even though i might agree with some that its closer to 350 than 450. For a reference, at the end of the video when i'm holding the head, i'm 6'4".. Watch full video below.
