Effects of visual impairment on the predation behavior. (A) Boxplots (median and interquartile values) of total number of predatory attacks by individuals with cataract in the eye on the mouth-opening side or those with cataract in the eye on the contralateral side. (B) Number of attacks on the non-dominant side by individuals with cataract in the eye on the mouth-opening side and those with cataract in the eye on the contralateral side. Wilcoxon rank-sum test was used to compare these values before and after the visual impairment. *: P < 0.05, ns: not significant. Seven fish were visually impaired on the mouth-opening side, and six fish were visually impaired on the contralateral side. The numbers of fish remain the same in Figs. 5 and 6.
