In the coastal city of Busan, South Korea, a group of citizens known as 'jagyeongdan'—a term blending the concepts of vigilante groups and neighborhood watches—has organized to monitor a shark trapped in a local canal. The shark, referred to locally as 'Bukang-i,' has been stranded in the urban waterway for approximately one month.

Equipped with high-visibility vests and recording equipment, these volunteers patrol the harbor area nightly. Their primary objective is to ensure the safety of the shark by deterring members of the public who might attempt to disturb or harass the animal. Many of the individuals involved are YouTubers who livestream their presence at the canal, documenting their efforts to guard the shark. While the group views their actions as a necessary protective measure for the animal's welfare, the situation highlights the intersection of local wildlife management and the rise of social media-driven public interest in urban environments.
