Beachgoers were left stunned this morning after a shark beached itself in front of them at Goode Beach.

Stephanie Janz watched the shark frolic in the shallows at Goode Beach in the morning, in an unusual display.

It was caught on video almost beached on the sand and chasing its own tail.

Ms Janz was walking along the beach at 7.45am when she spotted the shark in the shallows.

“It did swim back out again, it seemed to have been caught unaware by the swell in the shallows,” she said. “When we saw it, it was already on the shore and has almost beached itself.”

Department of Primary Industries and Regional Development fisheries research scientist, Alastair Harry said it was a blue shark, a true pelagic open ocean species, so it is unusual to see them in coastal waters or off a beach.

“It’s not possible to say why it has come to shore, but these things do happen to pelagic animals occasionally, it may be sick or injured, or have been carried off course by an oceanic current,” he said.

“It seems to be just disoriented and trying to get back into the water and it’s also well outside of its typical habitat.”

Mr Harry said beaching isn’t common or normal behaviour for sharks but it may happen for various reasons.
