(CNN) — Without so much as a wave of his flipper, Neil the boisterous young elephant seal departed Tasmania this week, leaving behind a legion of fans – and questions about what happens when he gets even bigger.
When Rebecca Thomson heard that Neil was back in town in June, she had rushed to the beach to see one of the Australian state’s best-known celebrities.
Then Neil, with all his 2,200 blubbery pounds, began following her.
“It’s like this giant slug coming at you,” laughed Thomson, who lives in the Tasmanian capital Hobart, and made sure to keep a safe distance from Neil. “It was really exciting and intriguing, and yes, definitely a bit intimidating, too.”
All southern elephant seals come on land a few times a year to breed, shed their fur, and interact with each other in gatherings of the otherwise solitary animals. But while most of his peers do this on remote subantarctic islands, Neil chooses to hang out with humans in the Australian island state during his seasonal visits – and wreak havoc.
After following Thomson to the parking lot, Neil began rocking a van, as bystanders laughed and the hapless driver tried to extract his vehicle. Other videos show him blocking roads; slamming into street signposts; peering through residents’ screen doors; and happily flattening traffic cones with his bulbous body. (He hasn’t, to date, threatened any humans.)
His stardom has only grown with each visit, winning him enamored fans around the world, and even a theme song. “He’s more ungovernable than ever,” one video caption read on a TikTok fanpage with more than 1.7 million followers.
“He features in advertising, local insurance ads, so yeah, he’s definitely become an icon,” Thomson said.
However, officials warned his virality had drawn too much attention, potentially jeopardizing his safety – a problem set to become worse as he grows in size and his online popularity skyrockets.
A solitary seal
Neil’s story began in 2020, when he was born off the southeast coast of Tasmania, not far from Hobart.
This, already, was unusual. Most southern elephant seals in this region are born on the uninhabited Macquarie Island, about 1,500 kilometers (932 miles) south of Hobart, and return to the same site to breed and give birth, said Clive McMahon, a research ecologist at the Sydney Institute of Marine Science.
But Neil’s mother may have been young and inexperienced and didn’t make it back to Macquarie Island on time. She was ready to give birth, and the Tasmanian beaches were right there – so out popped Neil.
Elephant seals “return to the place where they were born. So Neil is doing exactly what we would expect a good elephant seal to do… it just happens to be that he’s doing his normal behavior in a strange place,” said McMahon, who also lives in Hobart.
In the last four decades, as far as scientists know, only a handful of southern elephant seals have been born in Tasmania and survived, according to the Department of Natural Resources and Environment Tasmania (NRE Tas). Residents in Tasmania’s southern coastal towns now see Neil a few times a year on shore, where he’s legally protected as a vulnerable species.
There’s his molting season in December and January, when seals shed their old fur and outer layer of skin; breeding season, which takes place from September through November; and the enigmatic “mid-year haul-out,” which scientists still don’t fully understand.
During the haul-out from April through August, in the Tasmanian winter, elephant seals will gather and interact with each other – especially young males who
