A shark stranded in a canal in the South Korean port of Busan has become the country’s latest wildlife sensation, with the city saying about 6,00,000 people have flocked to see it over the past two weeks.The 3.5-metre (11.48-ft) shark was first spotted in a narrow waterway in North Port on September 18. As the days passed without the shark finding its way back to the ocean, authorities launched a rescue operation on Tuesday to guide it out, but the effort failed. The Coast Guard and other agencies deployed vessels to spray jets of water behind the shark to gently propel it toward the open ocean, but it swam away from the streams, according to videos published by Yonhap News Television.Officials now plan to use a net to try to guide the shark out of the canal on Friday, the Chosun Daily reported. The shark, reported to be a bronze whaler, has become something of a celebrity in South Korea and has been dubbed “Bukangi”, a nickname derived from “Buk Hang”, the Korean name for Busan’s North Port, and the Korean suffix “-i”.Rescue operation under way.

Other animal escapades have gripped South Korea in the past.Earlier this year, a wolf that escaped from its enclosure at a South Korean zoo spawned a cryptocurrency meme coin and even prompted a message of concern from the country’s president.
