The 'Paradox' of Poisonous Frog Resistance against Their Own Toxins Explained (6 of 16)

Caption

A male Machalilla rocket frog (Epipedobates machalilla) is loaded up with his young tadpoles. Males of this genus carry tadpoles from where they were laid to small pools of water, where they will complete their development into tiny poison frogs. This behavior is a type of parental care that is of great interest to biologists. Photographed in Cotopaxi Province, Ecuador in August 2017. This material relates to a paper that appeared in the Sept. 22, 2017, issue of Science, published by AAAS. The paper, by R.D. Tarvin at University of Texas at Austin in Austin, Texas, and colleagues was titled, "Interacting amino acid replacements allow poison frogs to evolve epibatidine resistance."
