Many people gathered near a canal in the city of Busan, South Korea, to watch a large shark. The shark is about three metres long, and people gave it the nickname Bukangi. People first saw the animal swimming in the waterway last month.
Experts think the shark entered the canal because the water was unusually warm and there were plenty of fish to eat. But the animal became stranded in the waterway and could not leave on its own.
Rescuers worked to guide Bukangi back to the sea. Government officials said on Thursday that the shark was guided out. However, on Friday, local media reported that Bukangi was still lingering near the entrance of the canal.
Rescuers then made another attempt to help the shark. Bukangi was successfully guided out of the waterway.
