Feb. 5, 2013 Most mammals, including humans, see in stereo and hear in stereo. But whether they can also smell in stereo is the subject of a long-standing scientific controversy.
Now, a new study shows definitively that the common mole (Scalopus aquaticus) - the same critter that disrupts the lawns and gardens of homeowners throughout the eastern United States, Canada and Mexico -- relies on stereo sniffing to locate its prey. The paper that describes this research, "Stereo and Serial Sniffing Guide Navigation to an Odor Source in a Mammals," was published on Feb. 5 in the journal Nature Communications.
"I came at this as a skeptic. I thought the moles' nostrils were too close together to effectively detect odor gradients," said Kenneth Catania, the Stevenson Professor of Biological Sciences at Vanderbilt University, who conducted the research.
What he found turned his assumptions upside down and opened new areas for potential future research. "The fact that moles use stereo odor cues to locate food suggests other mammals that rely heavily on their sense of smell, like dogs and pigs might also have this ability,"Catania said.

It took her about three seconds to find it. Stereo? Quad maybe!
but how do you get rid of them is the real point.
