caught something i never caught before

went to go get some cudas last wedsday on my 14 foot aluminum boat caught a bunch so i told joe dam the weathers not that bad let go to the cuban hole and throw two rods down for some shark we put both baits to the bottom about 30 mins later my rods screams i pick it up close the drag and it hooks itself i was useing a circle hook it starts running stright up to the surface and i see something out there that looks like its jumping i didnt know wat it was i couldent see it yet then it go's back down i bring him in closer and i see it a sea turtle it wasnt jumping it was coming up for air but still flapping its legs it was big as hell i felt really bad bringing him in to the boat but i didnt want to cut the line and it raps around him and it dies so i brought it really close and cut the wire really close to the hook i tryed taking out the hook but he only gave us 4 or 5 seconds before he started diving back down as soon as i cut the wire it dove right back down i dont think it will eat a cuda ever again it might just stay eat jelly fish
