"Bottlenose Dolphins Unveil Remarkable 'Seventh Sense' Ability"
Originally Published 2 years ago — by IFLScience
A study has found that bottlenose dolphins are more sensitive to electric fields than platypus, making them one of the few known mammals with this ability. The dolphins were tested and found to detect electric direct current (DC) fields as weak as 2.4 microvolts per centimeter. This suggests that electroreceptivity may play a more important role in dolphins' survival than previously thought. The study also revealed that dolphins are less adept at detecting alternating current (AC) fields. The researchers believe that dolphins use echolocation to detect prey at a distance and electric fields for close-range work.
