Moles sniff in stereo, experiment shows

Moles need both nostrils to locate food underground, in the way that humans see and hear in stereo, according to research reported on Tuesday. The common mole (Scalopus aquaticus) has tiny eyes tucked between fur and skin and is nearly blind, with small ears attuned only to low frequency sounds. Curious to understand how the little creature finds food in the dark, biologist Kenneth Catania at Vanderbilt University in Nashville, Tennessee, created a plexiglass chamber in his lab.
