A three metre mako shark has been captured on video circling a boat and repeatedly chomping on the propeller.
The video was released this week by Damien Dwyer. He filmed the shark for 10 to 15 minutes as it made the attempted attack.
"It was like Jaws, you could see the fin come up out of the water and it made a beeline towards us, it went around past the boat and started chewing on the motor," Mr Dwyer told PerthNow.
While Mr Dwyer and his wife tried to use a big piece of tuna to distract the shark, it only had eyes for the motor.
