“The study indicates that navigation ability is universal and not specific to the environment,” explains Shachar Givon, a researcher at the university’s Faculty of Natural Sciences. “Second, the study shows that goldfish have the cognitive ability to learn a complex task in a completely different environment than the one in which they evolved. Just like in driving school, the goldfish was put to the test on a special vehicle, basically a transparent tank filled with water and mounted on a trolley with four wheels. Thanks to a camera, the movements of the fish were recorded and then translated by software into commands to move the vehicle forward, backward, left or right. After a few days of training, the fish learned to drive the vehicle to the target, without being fooled by other distracting factors and correcting the trajectory every time it hit the wall.
