Bottlenose dolphins have astounded scientists with a remarkable sensory ability: electroreception, often dubbed their seventh sense.
While humans rely on taste, touch, smell, hearing, and sight, dolphins elevate their sensory repertoire with the detection of weak electric fields.
Recent studies, notably from the University of Rostock and Nuremberg Zoo in Germany, have illuminated this capability.
conducted experiments with captive dolphins named Dolly and Donna, revealing that these marine mammals can detect electric fields as faint as 2.4 to 5.5 microvolts per centimeter.
This sensitivity, attributed to specialized pores on their snouts called vibrissal crypts, allows dolphins to perceive electrical stimuli in their environment with remarkable precision.
The implications of this discovery extend beyond biological curiosity. Dolphins utilize electroreception not only to locate prey hidden in sediment but also potentially to navigate using Earth’s magnetic fields.
Lead researcher Guido Dehnhardt emphasizes that this ability enhances dolphins’ hunting efficiency, enabling them to pinpoint prey just before capturing it.
