“…Vegetation, soil, and water each transmit vibrations with less attenuation, faster, and over greater distances than does air, hence the numerous systems that have evolved to utilize this mode of communication. Numerous insect and arachnid species are known to communicate via vibrations through vegetation or soil (Barth, ; Cocroft & Rodriguez, ; Cokl & Virant‐Doberlet, ; Crowson, ; Gogala, , ; Senter, ;), elephants send and receive vibrations through earth (O'Connell‐Rodwell, ; O'Connell‐Rodwell et al, ), crocodilians respond to water‐borne vibrations (Leitch & Catania, ), and some frogs communicate via seismic and/or plant‐borne signals (Lewis et al, ; Lewis & Narins, ; Narins, Meenderink, Tumulty, Cobo‐Cuan, & Marquez, ). Numerous fishes emit vibrations into the water in which they reside (Fish & Mowbray, ; Ladich & Bass, ; Myrberg, ; Senter, ) and the mechanism by which they do this (Demski, Gerald, & Popper, ; Fine et al, , ; Tavolga, ; Zelick, Mann, & Popper, ) is very similar to the mechanism we hypothesize for chameleons.…”
