Observational analysis reveals bush frog modifies dorsal coloration with light detection, suggesting a unique camouflage mechanism.
During inactive daytime phases, the bush frog Raorchestes jayarami unconsciously changes its dorsal color to achieve rapid camouflage. For this, the frog detects light intensity changes through its skin, potentially bypassing traditional neural and hormonal pathways. This hypothesis is supported by correlations with environmental variables and experimentally induced color change. രത്നച്ചുരുക്കം
