A collection of 37 Natal reed-frogs, Hyperolius marmoralus, from a single locality was studied for their dorsal colour patterns. Data were assembled on the spectrophotometry, the structure and distribution of the chromatophores by means of light and electron microscopy, and the features of colour ...
testosterone and 17β-estradiol induced the development of adult male and female colour, respectively, in two frog species (Greenberg, 1942, Hayes and Menendez, 1999). Sex steroid receptors are present in the integument of amphibians (Sever and Staub, 2011), even in tadpoles’ skin before ...

4. The integument of poikilotherms is exposed, and altering skin colour/reflectance is considered an important physiological process that contributes to thermoregulation3,5,6. Poikilotherms also use behavioural responses to thermoregulate; basking7,8, shuttling between environments9, burrowing underground...
