Falkiner needed more than 20 minutes to boat this toothy critter fish after it nailed the CD Magnum Rapala plug he was trolling. Accordi to IGFA it is butterfly kingfish, butterfly tuna, or bigscale mackerel. This strange specie has many common names but its one scientific name is "Gasterochisma melampus".
