Boxplot showing size differences in morphological structures of the Pallenopsis patagonica species complex. All comparisons show that characters of samples from ANT (Antarctica) are significantly larger than from SUB (Patagonian) (log10 of absolute values used; p = 0.0000005, p = 0.00008, p = 0.00042 and p = 0.00012, respectively)
