A Busan dusky shark nicknamed Bukangi has pulled in almost 1.4 million onlookers since she turned up in a shallow canal in the South Korean port city in the middle of September, according to local authorities cited by Mongabay.
The 10-foot (3-meter) female dusky shark (Carcharhinus obscurus) is stuck in a waterfront park canal between skyscrapers and a passenger ferry port. At least two attempts to guide her to open sea have failed, and videos of her swimming past the city skyline have gone viral.
Busan has made her an honorary city ambassador and assigns more than 100 workers a day to watch for signs of poor health. The local baseball team and a distillery have both released Bukangi-themed products, including soju bottles.
A warning sign, or a one-off?
Some groups see more than a curiosity. South Korea’s Green Party criticized the lighthearted mood in a September statement. “The shark did not come here to entertain us,” the party said. The Hankyoreh newspaper made a similar argument in an editorial.
Government figures point to warming and more large sharks. South Korea’s meteorological service said in August that surface waters around the Korean Peninsula have warmed by 0.7 degrees Celsius in a decade, more than double the global average.
The National Institute of Fisheries Sciences (NIFS) logged 46 shark sightings in eastern waters as of mid-2026, compared with 12 in 2025. It linked the rise to warm-current prey such as yellowtail and Pacific bluefin tuna moving north. It also counted at least 73 shark bycatch cases from January to August 2026, about 2.5 times the same period last year.
The two scientists Mongabay interviewed were cautious about Bukangi herself. “We cannot conclude that global warming directly caused this particular shark to enter Busan’s North Port,” Hong Sun-kee of Mokpo National University’s marine and island cultures institute told Mongabay. He said prey location, currents, tides and the shape of the waterway also need study.
Kim Tae-won, a professor of ocean sciences at Inha University, said dusky sharks tend to prefer waters of 18 to 28 degrees Celsius (64 to 82 degrees Fahrenheit), and that warming could expand suitable habitat northward. “A single observation is not sufficient to establish such a connection scientifically,” Kim said.
What happens next
The Busan city government and NIFS plan to keep monitoring Bukangi before deciding whether to try another rescue, Mongabay reported. Earlier this week, authorities also said they would work on ways to keep sharks away from beaches in the future.
Dusky sharks are highly migratory and found in many parts of the world, according to the Florida Museum’s species profile. They grow slowly, mature at roughly 16 to 23 years and have small litters, which makes them vulnerable to overfishing. Mongabay lists the species as endangered on the IUCN Red List, while the museum profile lists it as vulnerable.
Hong said he hopes the attention will lead to more research. Tracking changes in species ranges, food webs and habitats alongside water temperature and currents, he said, would help scientists tell temporary events from long-term trends.
