Teenage fishermen from Port Hedland stunned after landing sawfish, one of the world's largest and rarest fish species

Amazing footage captured the moment three teenagers reeled in a giant six-metre sawfish while fishing on a beach.

Owen Wells and three of his high school friends were on the beach at Port Hedland, near Karratha in Western Australia's far northwest, in November when the trio noticed something strange.

While the teens caught many small fish, Owen noticed that one particular fish was pulling more strongly on the end of his fishing line.

“There was a huge run… and it just kept going,” he told the station ABC.

What followed was a two and a half hour battle to reel in the fish before the boys were astonished to discover that Owen had caught a huge green sawfish measuring approximately six meters in length.

Video uploaded to Instagram showed the moment Owen reeled in the fish as storms and heavy winds battered the beach.

The hook at the end of the line was firmly in the fish's nose as it was pulled onto the beach.

The shocked teens quickly tried to pull the sawfish further into the sand before Owen posed for photos with the endangered creature created by his friends.

Owen said it took six people to drag the fish across the sand and described the surreal moment of catching the huge fish.

'It was just so strong. “I felt like I had hooked a train or a submarine,” he said.

“It looks like a dinosaur when you stand next to it.”

Green sawfish is a rare species found along coastal waters, rivers and beaches in northern Australia.

The sea animal has a shark-like body and can be recognized by a distinctive thin, long nose that protrudes from the front of the animal's body.

The nose has up to 28 pairs of so-called 'rostral teeth' on the side of the leaf-like snout.

Sawfish usually grow up to five meters in length in Australian waters, but the animal can grow up to 7.6 meters in length.

The endangered species is prone to getting entangled in fishing and shark nets because of its long nose.

Although the current population of the species in Australia is unknown, the animal is considered extinct on the east coast, according to the Australian Marine Conservation Society, with the species last seen in NSW in 1972.

Owen said he and his friends worked quickly to release the fish back into the water because the law requires sawfish to be released once caught.
