(CNN) -- A leisurely day of sport fishing ended with an exhilarating struggle Sunday when a group of fishermen landed a massive thresher shark off the coast of Florida.
After two hours of fighting to reel in the 650-pound, 13-foot-long shark, Floridian Jason Fox, 30, landed the fish that he described Monday as simply "huge."
"This is really just a once-in-a-lifetime fish," he said.
Fox caught the fish off the coast of Dania Beach, Florida, about five miles south of Fort Lauderdale.
The state record for the largest thresher shark was set in 1984 when a local fisherman caught a 544-pound shark near Destin, according to the Florida Fish and Wildlife Conservation Commission.
Fox and a group of friends chartered a sport fishing boat to celebrate a family friend's birthday. They were initially pleased with the day's catch of kingfish and tuna but were stunned by the final catch.
"We just went out for a fishing trip ... and at the end of the day the captain asked me if I wanted to catch a shark," Fox said. He added he's reeled in a 150-pound fish before, but never anything this big.
Fox caught the shark in 350 feet of water, CNN affiliate WSVN reported. Fox said he plans to mount it on his wall.
Thresher sharks -- named for their extremely long tails -- are found throughout the world in temperate to tropical seas.
