It, weighing about 10kg, has a plastic ring, one centimeter wide and 5 centimeters long, in its left leg.

Up to now ringed birds have been found in the country several times but it was the first time to find a ringed turtle. Now experts are studying the turtle.

Officials of the Nature Conservation Union of Korea told KCNA that the discovery was probably attributable to the ecological environment of the Korean coastal waters turning favorable for sea animals and that they would invigorate exchange with the International Union for Conservation of Nature (IUCN) and nature conservation organizations of other countries.
