Question

Chromatophores in a frog's skin are controlled by what?

Answer 1

Color of amphibians is affected by the presence of pigment cells (chromatophores) in the dermal layer of the skin. Three classes of chromatophores are melanophores, iridophores, and xanthophores. The primary pigment in melanophores is eumelanin, which imparts black, brown, or red coloration.

Answer 2

The chromatophores in frog's skin are the pigments that impart the specific colour to skin. These pigments are controlled by various hormones secreted in frog's body which are melanocortins, melatonin and melanin-concentrating hormone (MCH).
