Archerfish learn to hit rapidly moving targets by observing other
archerfish. Observer archerfish allowed to watch a school member
(model) improving its accuracy are almost as accurate on their first
shot as the model fish was after more than 1000 shots. Crosshatched
bar, initial success of model; open bar, success of model after training;
solid bar, average success of observer on its first shot having watched
the model. The target was 54 cm above the water and was moving at
5 cm/s. After Schuster et al. (2006).
