Bukhangi the shark circles slowly in a narrow channel of water, unaware that he’s become Busan’s most famous resident.

The 3.5-meter bull shark appeared in an artificial waterway in the southeastern port city, drawing thousands of onlookers, news crews, and even the attention of the mayor. Locals quickly gave him a nickname—Bukhangi, a playful blend of “Busan” and “shark”—and affection for the unexpected visitor grew by the hour.

This isn’t just a quirky animal story. Bukhangi has sparked a wave of joy and economic energy in the city. Sales of shark-shaped ice cream bars jumped nearly 30% in nearby convenience stores. The Pinkfong Company, known for the global hit “Baby Shark,” saw its shares rise over 7% as fans made playful connections between the song and the real-life shark. Even the mayor got in on the moment—Chun Jae-soo publicly thanked Bukhangi, saying the free publicity would have cost trillions of won if bought through advertising.

In a symbolic gesture, the city held a vote to name an honorary public relations ambassador. Bukhangi won with 91% of the vote, a landslide no human candidate could dream of.

Scientists say the shark’s presence may be linked to rising sea temperatures. Bull sharks usually prefer warmer, tropical waters, but as waters around South Korea warm, animals like this one are appearing in places they’ve rarely been seen before. Kim Jin-koo, a fisheries professor at Pukyong National University, said sharks in these waters are “not common at all”—making Bukhangi both a novelty and a quiet signal of changing seas.

With fame came myths. Soon after Bukhangi’s appearance, rumors spread of a second shark—some claimed it was his pup, sharing AI-generated images of the two swimming together. But officials confirmed: there’s only one shark, and no mate or baby has been spotted.

Authorities plan another attempt to guide Bukhangi back to the open sea, using coast guard boats to spray water and encourage him toward the ocean. But for now, he remains in the waterway, a calm center in a storm of attention.

Bukhangi joins a small but growing list of animal celebrities in South Korea, like Neukgu, the young wolf who escaped a zoo earlier this year and captured hearts during his nine-day journey through the wild. These animals don’t speak, yet they stir something deep—a reminder of nature’s mystery, and how a single creature can bring a city together, even if just for a moment.
