Behavioral evidence for spatial vision in snapping shrimp. In this representative movie, a snapping shrimp (A. heterochaelis) is seen following moving stripes with angular widths of 20°. When the stimulus changes direction, the shrimp also changes direction to follow the stimulus. This video is a subsample of the full-length video.
