Only a handful of mammals have the “seventh sense” of detecting electrical fields. For many years, this checklist has been exclusively restricted to the platypus and the echidna. Even so, a modern examine has identified that the bottlenose dolphin is also able of sensing these electrical fields.

The review was performed with two bottlenose dolphins from Nuremberg Zoo in Germany named Dolly and Donna. The animals had been instructed to rest their jaws on platforms and swim away at any time they skilled a sensory cue, which involved seems, flashes of lights, and, once the dolphins were being trained, electrical signals. Extremely, the pair of dolphins responded properly on the to start with demo, indicating a wonderful stage of electric sensitivity—or electroreception.

Sharks, who are related aquatic predators to dolphins, have been working with electroreception to hunt their prey for centuries. On the other hand, given that dolphins also use echolocation to hunt, it is unclear why they also possess this sensitivity. It is feasible that it helps them feeling prey on the seafloor, as fish develop smaller electrical fields through the movement of their gills.

Bottlenose dolphins also have a much more assorted diet regime than other species of dolphin and have been known to entry fish caught in traps without the need of acquiring caught on their own. It is possible that as the relaxation of their senses have enhanced above generations, so have their electroreceptive capabilities.
