Which animal has the best nose?

Animals have far more odor-sensing genes than any other mammal, even dogs. Dogs, most of us think, have the best noses on the planet. But a new study reveals that this honor actually goes to elephants. The power of a mammal's sniffer hinges on the number and type of its olfactory receptor genes.Animals have far more odor-sensing genes than any other mammal, even dogs.
