Cylinder and Cube Shape Discrimination by an Echolocating Blindfolded Bottlenosed Dolphin
An Atlantic bottlenosed dolphin was trained to wear rubber eyecup blindfolds and to choose a cylinder as compared to a cube when the two targets were simultaneously presented. The animal was housed and tested within a circular fiberglass tank filled with filtered sea water. As may be seen in Fig. 1, the animal was trained to station within the tank and echolocate down a water-filled trough.
