Mating behavior recorded in Trial I and Trial II. (A) Number of mating behaviors for each male squid in Trial I. (B) Box-and-whisker plots of mating duration for each male squid in Trial I. (C) Number of mating behaviors for each male squid in Trial II. (D) Box-and-whisker plots of mating duration for each male squid in Trial II. Note: in (B) and (D), the thick line in each box plot is the median. The cross is the average. The limits of the boxes indicate the lower (Q1) and upper quartile (Q3) of the distribution. The length of the box is the interquartile range (IQR). The limits of the whiskers are the data points within the calculated minimum value (Q1–1.5 × IQR) and the calculated maximum value (Q3 + 1.5 × IQR). The data points outside the whiskers are outliers.
