Allometric relationships through ontogeny. Aquatic and terrestrial individuals show different relationships between tail morphology (y axis) and size (x axis), represented by the two large grey arrows. A: Larvae in ephemeral environments undergo early metamorphosis and transform into terrestrial individuals at a small size. SVL_m shows the minimum size for metamorphosis. B: Larvae in more permanent environments delay metamorphosis and transform into terrestrial adults at larger body sizes. C: In permanent aquatic environments, some larvae forgo metamorphosis to become reproductively mature neotenic paedomorphs.
