Fun Fact of the day


Sharks "smell in stereo."

You're no doubt familiar with a shark's ability to detect even small amounts of blood in the water from as far as a quarter mile away. However, what you may not realize is that this is due to the animal's ability to "smell in stereo."

As reported by Nature in 2010: researchers found that sharks can detect tiny delays in the time it takes for a scent to reach one nostril compared to the other—even when it's just a fraction of a second. This delay allows them to determine from which side the scent came and in response, they can head that way in search of prey.
