Abstract: Light-induced pigmentation changes are widespread among tadpole species. In this study we characterised light-induced changes in melanin dispersion through development in cane toad tadpoles (Rhinella marina). We describe a pattern of light-induced pigmentation change in which tadpoles are darker in the presence of light and lighter in darkness until the onset of metamorphosis. This pattern contrasts with that of other non-bufonid tadpole species, but mimics the pattern of pigment change exhibited by embryonic anurans. We discuss our results in light of the ontogenetic changes in toxicity to evaluate the photoresponse of cane toad tadpole pigments as a potential aposematic signal, neotenic trait, and thermal adaptation.

IMPORTANT NOTE - JUNE 2020

Please note that as from Volume 31 Number 1 (January 2021) on, the Herpetological Journal will be available as an online publication only - the last print edition will be Volume 30 Number 4.   

Aligning with this change, it is now no longer possible to purchase a subscription that includes a print copy of the HJ.  All members who have existing HJ print subscriptions that remain active as at end June 2020 will receive the full four 2020 print editions.  New subscribers or renewals after this time will only have option to subscribe to the online only subscription package.  Subscription pricing has been amended to reflect the content changes.
