The picture, taken at Carrum Beach, showed a father and his young daughter smiling and waving at the camera — completely unaware that something eerie seemed to be lurking just behind them in the water.
A Viral Mystery
It wasn’t until the family got home that they noticed the strange shape rising from the waves only a few feet away. When they shared the image online, it quickly went viral in 2023, sparking fierce debate over what it showed — a shark, or simply an optical illusion caused by the water?
Now, years later, the unsettling photo has resurfaced and gone viral once again.
According to local reports, the timing wasn’t random. On the same day the photo was taken, SES Chelsea had issued a public warning about a shark sighting between Bonbeach and Chelsea.
In a Facebook post, the group explained:
“We’d just posted about a shark sighting when a family messaged us. They’d been at Carrum Beach that morning for their child’s first visit. Later, when they checked their photos at home, they spotted something strange in the shallows. Could this have been our shark?”
The post blew up instantly, dividing social media users.
One person commented:
“It couldn’t have been a big shark, judging by how shallow the water is and the dog standing nearby.”
Another added:
“Looks too shallow for a shark with a fin that size — and surely the people in the photo would’ve noticed!”
A third wrote:
“I wouldn’t rule it out completely, but it’s very unlikely a shark could swim that close to shore without anyone realizing.”
Experts Weigh In
Authorities couldn’t confirm whether it was truly a shark. Both Life Saving Victoria and the Victoria Fisheries Authority (VFA) found no evidence.
Professor Charlie Huveneers, head of the Southern Shark Ecology Group, offered a more plausible explanation: he believes the “fin” in question was actually the wing of a Southern Eagle Ray.
“The image quality makes it hard to be sure,” he told Yahoo News Australia. “But the shape doesn’t look like a shark’s dorsal fin — it’s more consistent with a stingray, which often swim close to shore.”
The Southern Eagle Ray, a near-threatened species native to southern Australia, is commonly seen in shallow waters and even around New Zealand.
The mysterious image re-emerged online just days after fishermen off Aldinga Beach, near Adelaide, captured footage of a massive great white shark — estimated at 13 feet long — circling their boat.
Authorities have again urged swimmers to remain cautious, as the debate over the now-famous beach photo continues to spark both fascination and chills across Australia.
