i doubt it, that looks like they are down around Boca. i dont hardly see any hammerheads around sp beach (which is where your all thinking this is) tend to see them in 10-12' water and alot closer to the channels. and more predominantly around anna maria/holmes beach

that tarpon was no 140lbs...it was small, maybe 110ish at best. i've never seen such poor tarpon fishing in my life, but i guess since it was kids, its kinda ok. they should have let the tarpon free spool and ran with it if they wanted to keep it on the line...personally when they coulda touched the leader they should have cut it and let it run.
