GOLF legend Greg Norman caught "the biggest catch ever", a giant hammerhead shark - after it ate a smaller one they'd already reeled in.
In his golfing career, the former world's No1, won 91 international tournaments including two majors - the Open Championships in 1986 and 1999.
But, nicknamed The Great White Shark after his play at the 1981 Masters, Norman, 64, has now swapped his golf club for a rod and reel.
The beast was estimated to weigh around 600kg and towed the fishermen's 10,000kg boat along when it made a beeline for the 6ft blacktip shark.
Norman, alongside TV host Joshua Jorgensen, caught the moment on a drone camera for the online fishing show BlacktipH, which is shot in Florida.
The Australian Hall of Famer caught the blacktip and soon realised that the hammerhead was stalking behind it.
It managed to catch the smaller creature, weighing around 45kg, before eventually swallowing it.
The shark was measured at 14.6ft tall, 10cm longer than the current record for the biggest hammerhead ever caught.
Norman said: "We hooked a blacktip and all of a sudden this giant hammerhead came flying in on the blacktip.
It was the most incredible scene Ive ever witnessed

"It was the most incredible scene Ive ever witnessed."
The 64-year-old strapped into a fishing harness as he attempted to reel in the hammerhead in what he called "the fight of the year".
As the mammoth shark started to swim away from the 12.5m boat, it actually had enough power to tow the vessel which Norman suggested weighed over 10,000kg.
He said: When you start thinking about the poundage that this fish is pulling around, not just the boat but the people on the boat and the fuel on the boat, that is an impressive statement about the energy and the power of these magnificent animals."
Jorgensen added: Its insane. These fish are so powerful, its unbelievable.
RECORD BREAKER
The duel continued until the boat caught up to the tiring shark, which was within metres of the boat.
Norman added: When you see that fish for the first time up against my 41-foot boat you go, Holy moly, this things huge. Its bigger than I ever anticipated.'"
The crew kept the shark in place by tying rope around its head and tail for long enough to grab some photos.
They then spent about 40 minutes reviving the hammerhead, getting water into its gills.
Daredevil Norman then jumped into the sea while the shark was still swimming around the area.
He said: "We wanted to feel connected to this fish. We wanted this fish to feel like, OK, these guys are really trying to revive and get me going."
The crew measured the hammerhead with rope and claim it was 4.44m long - 10cm longer than the official world record for the largest hammerhead ever caught.
But because Norman and his sidekicks released the shark, their record wont be recognised.
