Fig. 4. (A,B) Distribution histograms for heights of newborn seahorses from large parents (A) and small parents (B). Heights of newborns from the six large males showed a pronounced negative skew (coefficient of skew=-0.446; N=298; Shapiro-Wilks test; P=0.0018) but the newborns from small males did not show this skew (N=262). (C,D) Medians and 25th percentiles for the height distributions (mm) of newborn seahorse cohorts from large parents (C) and small parents (D) between weeks 1 and 7. Distributions with significant negative skews are indicated (^*P<0.05 and ^**P<0.01).
