Presumed to be a bull shark, but exact species unconfirmed Large sharks reaching 2–3 meters in length confirmed in succession recently [Anchor] Appearances of large sharks are occurring one after another, centered around Jeju and the East Coast. As water temperatures rise due to the climate crisis, the ecosystem of our seas is changing rapidly. Reporter Go Jae-hyung covered the story. [Reporter] A shark of massive size swims leisurely in the blue waters. Considering its size and shape, it is presumed to be a bull shark, but the exact species has not been confirmed. [Park Shin-hye / Haenyeo: There was a shark as big as a human body, and around it, a school of smaller sharks were circling in a circle around us before leisurely swimming away. I was quite surprised to see the shark...] Over the past three years, the Coast Guard has officially confirmed a total of 14 cases of shark sightings in the waters off Jeju. In particular, large sharks reaching 2 to 3 meters in length have been spotted one after another recently. Experts believe that the appearance of large sharks is increasing as the distribution of fish species in our seas changes due to rising water temperatures caused by climate change. In fact, along the East Coast, where bluefin tuna catches have significantly increased, cases of large sharks being caught as bycatch are also rising. [Yoon Sang-hoon / Senior Specialist at the Center for Marine Citizen Science: As prey species migrate northward in large numbers to the waters off Jeju and the East Coast, these sharks are coming up with them. Due to the high ocean temperatures caused by the climate crisis, sharks are not leaving and are staying in the Korean Peninsula year-round...] As the marine environment changes due to the climate crisis, the ecosystem map of the waters around the Korean Peninsula is changing. The frequent appearance of sharks is a clear signal demonstrating the acceleration of global warming in our seas. As the speed of environmental change accelerates, we must urgently establish a more thorough and scientific marine observation system. This is Ko Jae-hyung from YTN. The frequent appearance of sharks is a clear signal that global warming is accelerating in our seas.
