The BBC, The Guardian and The New York Times report on a shark nicknamed Bukangi, about 3 metres (10 feet) long, that was stranded for more than a month in a canal in Busan, South Korea. Crowds gathered to watch the rescue attempts, and The Guardian reports that more than 1.6 million people visited. The BBC reports that a third attempt, using nets to guide the shark, was made. The Guardian and The New York Times report that the shark was guided out to open water on that attempt, and The Guardian attributes this to South Korea’s oceans ministry, which said officials expected her to move into open water. The BBC reports that it is thought warm water and plentiful fish drew the shark into the canal.
