So you think your dog has a pretty good nose? Let me ask you this: can your dog track a whale across the ocean just by the scent of its, uh... effluvium? This dog can.

From this story in the New York Times (And a hat tip to Phil Bourjaily for the find):

A dog named Tucker with a thumping tail and a mysterious past as a stray on the streets of Seattle has become an unexpected star in the realm of canine-assisted science. He is the world’s only working dog, marine biologists say, able to find and track the scent of orca scat, or feces, in open ocean water — up to a mile away, in the smallest of specks.
