From: How warm is too warm for the life cycle of actinopterygian fishes?
Egg diameters suitable for sufficient oxygen supply under a given water temperature.
A and B, saltwater; C and D, non-saltwater. Curves represent predictions from eq. 3, with the real line representing the mean prediction and dashed lines upper prediction intervals with associated percentages. The intervals were derived from the possible range of metabolic rates for eggs of a given size under a given temperature. Thus, species above the mean prediction have metabolic rates that are below average. Empirical data of the egg size and reproduction temperature for fish species are superimposed. A and C, smooth spherical eggs without parental care; B and D, other eggs, with either parental care, post-fertilization expansion of perivitelline space, or surface ornamentation. Empirical data were compiled from the literature listed in Supplementary Data.
