Incredible footage shot from a drone shows the epic struggle between a fisherman and a huge hammerhead shark on the shores of Panama City, Panama.
"Flying around and noticed a crowd," wrote Curtis Williams, who was piloting the drone, on his YouTube page, where he posted the video. "Turns out a guy was pulling in a massive hammerhead."
The video captures two minutes of the feat as the fisherman patiently but firmly reels in the powerful hammerhead. The man with the rod belongs to a group called Modern Day Outdoors, which puts on spectacles like this for entertainment.
"It just goes to show that anyone with a kayak and a rod can reel in the big ones," said a post on the Modern Day Outdoors Facebook page, which shared Williams's video.
Williams said his iPad in the drone, which was recording the video, ran out of battery before it could capture the man releasing the hammerhead shark back into the sea. "They were pros, even stayed in water until it was good to go," Williams said.
The sharks can grow to 20ft in length, up to 1,000 lbs (453kg) in weight, and live for 30 years. They have razor-sharp teeth and are fearsome predators.
"Hammerheads are aggressive hunters, feeding on smaller fish, octopuses, squid, and crustaceans," according to National Geographic. "They do not actively seek out human prey, but are very defensive and will attack when provoked."
