Single target acuity for moving targets in the common sunfish (Lepomis gibbosus).

The common sunfish (Lepomis gibbosus) likely relies on vision for many vital behaviors that require the perception of small objects such as detection of prey items or body marks of conspecifics. A previous study documented the single target acuity (STA) for stationary targets. Under many, if not most, circumstances, however, objects of interest are moving, which is why the current study tested the effect of the ecologically relevant parameter motion on sunfish STA.
