FILE - In this Jan. 18, 2014, file photo, a female orca leaps from the water while breaching in Puget Sound west of Seattle, as seen from a federal research vessel that has been tracking the whale. Using unique breath samples captured over four years, a new study identifies an array of bacteria and fungi contained in the exhaled breath of the small, distinct population of southern resident killer whales of the northeast Pacific Ocean.
