Growth and polyp development of spat in an ex situ experiment

Points are spat diameter (left axis) with increasing age on the x axis fitted to a linear trend line corresponding to the equation shown in each facet (n individuals per treatment: DD = 4, DS = 6, SD = 10, SS = 14). Gray area around the trend line is 95% confidence interval. Boxplots (right y axis) indicate number of polyps per spat with age, with the central primary polyp after metamorphosis counting as one. Horizontal black lines within boxes are median values and box limits represent first and third quartiles. Whiskers represent 1.5 times the interquartile range.
