Abstract: We demonstrate that Darwin's frogs (Rhinoderma darwinii) show sex differences in dorsal pattern and body coloration. Males possessed higher variability than females, which were mainly brown; two dorsal patterns and a green body colour were found exclusively in males. Males at different reproductive stages differed significantly in body colour and dorsal pattern; brooding males were characterized by being greener. Females, which were almost exclusively brown, were mostly found on brown substrates, whereas males were distributed across brown, green and brown/green substrates. An association between body and substrate coloration suggests crypsis to reduce predation risk.
