Scientists often create elaborate studies in order to tease out secrets and truths from the animal world. One such work has recently been published, with a group from Ben-Gurion University hoping to determine the true nature of a fish's navigation capabilities, as shared on Twitter. Several goldfish were tasked with driving a robot towards a goal, with the sea creatures proving more than up to the job. As per the paper available online, the apparatus for the test was relatively straightforward. Goldfish were placed in a small transparent tank of water placed on top of a robot chassis. A camera mounted above the tank tracked the fish's position and orientation. If the fish swam outward towards a given wall, the robot would move in that direction. When the fish drove up to a pink target on the wall, they would be rewarded with food.
