Closely related electric fish species from the Okano River of Gabon, collected in the vicinity of the abandoned Fang village, “Na.” Each species is shown along with a recording of its electric organ discharge, which these fish use to communicate with one another and electro-locate prey, much like bats use echolocation. Electric fish recognize other members of their own species using the species-specific waveforms of these heartbeat-like discharges. NIH funding from the National Institute of General Medical Sciences...From FASEB (abbreviated, and boldface mine). I suppose as a basic principle, there's no difference between communicating using electical waveforms vs. communicating using auditory or visual waveforms, but the idea still staggers my mind. Fascinating. I wonder if there is other information they can share, besides just "I am here."
