Some like it hot: heat tolerance of the Crab-eating Frog, Fejervarya cancrivora (Note)

Abstract

We used Critical Thermal Methodology to quantify thermal tolerance of the crab-eating frog, Fejervarya cancrivora,from Hoga Island, southeast Sulawesi, Indonesia. The critical thermal maximum of F. cancrivora was 42.1 ± 0.76°C, and is perhaps the highest thermal tolerance value known in an anuran acclimatized to 25°C. The frogs’ ability to tolerate extreme high temperatures allows them to exploit abiotically harsh mangal habitats and accounts for their wide distribution across the tropical Pacific.
