Vibrational Communication in Animals

In creatures as different as crickets and scorpions, mole rats and elephants, there exists an overlooked channel of communication: signals transmitted as vibrations through a solid substrate. Peggy Hill summarizes a generation of groundbreaking work by scientists around the world on this long understudied form of animal communication. Beginning in the 1970s, Hill explains, powerful computers and listening devices allowed scientists to record and interpret vibrational signals.
