In Donetsk, Ukraine, 14-year-old Kirill Dudko recently made an undersea discovery. While watching a Canadian live-streamed video broadcast from the sea floor, Kirill noticed an unusual creature devouring a fish. When he wrote to the scientists in search of information, they identified it as an elephant seal hunting almost 1 kilometer under the surface. The Canadians were thrilled at the Donetsk youngster's discovery, which led them to the first-ever images of one of the world's deepest-diving mammals at work so far underwater. As RFE/RL's Ukrainian Service found out, Kirill himself can barely believe he helped make a scientific breakthrough.
