Extended Data Fig. 1: Latitudinal gradients in egg size (predictions from the phylogenetically controlled model).

Panel a, Egg size (μm) of planktotrophic larvae across latitudes. Panel b, Egg size (μm) of lecithotrophic larvae across latitudes. The gradient from dark to light red shows large to small egg sizes. Note that the scale differs between panels. White circles show the distribution of studies from which data was obtained. Larger circles indicate a higher number of studies.
