Elephants "Hear" through Feet

More on vibrotactile sensitivity in elephants in this lengthy article which adds new insights into the 1990's discovery.

"In August, the Journal of the Acoustical Society of America will detail her new findings that elephants can detect subtle frequency differences in vibrations and react accordingly." The test of this seems to show that elephants are more likely to respond quickly to a warning "call" from elephants they recognize (by their distinctive "accent" or "voice") rather than to warning vibrations from elephants they do not recognize, but do understand.

Like I might "duck" or "run" if a friend's voice shouts out one of those commands. I might also do it if a stranger shouts the commands, but I might think more about it first or do it slower.
