Hair-raising footage has emerged of a 10ft long shark biting down on a boat's motor.
Earlier this week, captain Matt Zen went to Coral Bay in Perth, Australia, with his friends for their annual fishing trip - but they had no idea what was about to happen.
For about an hour, the group had been fighting with a three-meter-long copper shark they had been able to hook when things took an unexpected turn.
In a video shared on Instagram, the giant beast - also known as a bronze whaler - can be seen moving in the water at the end of the boat when they suddenly took a big bite onto the vessel's motor.
"Shark attacks our boat! He latched on to the propeller and wouldn't let go," wrote Matt in the post, as reported by the Daily Star.
"He is a monster, he has chomped the motor," one crewmate yells in awe.
"Oh man, this is nuts."
The predator stays at the position for some time before the crew becomes worried and tried to save the shark.
"After five minutes of lifting and dropping the engine, he finally swam away," said Matt, of Fever Fishing.
"We got the hook out and he finally got over the taste of the motor. Great relief to see the toothy critter let go of the motor and swim back to the depths."
Jarryd England, one of the fishermen, recalled the incident and told 9News that the shark "basically inhaled the entire propeller".
Both the copper shark and the boat were unharmed in the incident.
Two weeks ago also in Australia, a paddleboarder had a very close encounter with a hungry tiger shark when he found himself getting in the way of the predator while it was hunting a sea turtle.
Brodie Moss filmed the moment the sea beast leaped out of the water and took a big bite on his paddleboard.
The sudden force pushed Brodie off his board and he fell into the water, but fortunately he was unharmed in the nail-bitting incident.
"Tiger shark and this turtle - big showdown, and I'm right in the thick of it," he can be heard saying in a video.
