The article presents information on the discovery that some stealthy mammals can use their sense of smell underwater, by Kenneth Catania, a researcher in the Vanderbilt University, Nashville, Tennessee. Catania seemed to have found the case totally surprising as he had the idea that mammals can hardly smell underwater. The discovery came to light after Catania observed that a mole could blow several bubbles while swimming. He placed pieces of earthworm, small fish, and insect outside at the bottom of a tank to observe the moles' behavior, who noticed that when the moles came near to any of these objects, they would blow bubbles that came into contact with the object's surface, and then were sucked back into the nostrils.
