Narwhal Tusks are Sensory Organs
PR0UD_INFIDEL writes "The New York Times is reporting that a recent study has determined that Narwhal tusks are not for fighting or breaking through ice, but are highly sensitive sensory organs. From the article: 'The close-ups showed that 10 million nerve endings tunnel from the tusk's core toward its outer surface, [and can] detect subtle changes of temperature, pressure, particle gradients and probably much else.'"
Dudes, it's not Nar-whale 'cause it's a whale... it's "Narwhal" without the "e". Common mistake, though.
Yes, you are :)
