Fish beware: Bottlenosed dolphins may be able to pick up your heartbeat
To snap up fish, bottlenosed dolphins may rely on more than just sharp sight and sonar detection. The creatures might also pick up on the weak electric pulses prey produce each time their hearts beat or air filters through their gills. In a new experiment, two bottlenosed dolphins named Dolly and Donna reliably sensed faint…
Bottlenose dolphins can sense electric fields with their snouts
Donna, a bottlenose dolphin, during a test for electricity-sensing abilities Tim Hüttner, Nuremberg Zoo Bottlenose dolphins have an extra sense – the ability to feel electric fields – which they may use to navigate and search for food. The power to sense weak electric fields, known as electroreception, is common among water-dwelling animals, such as…
