Summary
Researchers placed electrodes in a pool with a dolphin. When activated, the electrodes created a weak electric field, causing the dolphin to swim away. When they were not activated, the dolphin behaved normally. After covering the dolphin's vibrissal crypts with a plastic shield, the dolphin no longer swam away when the electrodes were activated.
Strongly Supported Conclusions
The vibrissal crypts impact a dolphin’s ability to detect electric fields.
Dolphins instinctively swim from electrical fields
