Fargo, the dog pictured here, is not just having a nice day at sea. He is helping researchers at the New England Aquarium in Boston detect scat (or poop) from North Atlantic right whales. The dogs find about four times more whale poop with their scent detection than the researchers would using other methods. Researchers analyze the scat to learn more about the health and reproduction of the whales. There are also scat-sniffing dogs in the Pacific helping to locate orca feces.
