Until recently, most of what scientists know about whales comes from dissecting the ones that have washed ashore or through examining captive specimens.
Now scientists are using small, remotely controlled helos to maneuver above a whale’s blowhole and sample the mist it blows into the air. Their blowhole could be thought of as somewhat similar to our nostrils in the sense that during exhale there’s an accumulation of mucus and other interesting matter. These samples can reveal bacteria lurking in these beasts.
