Coupling skin colour with the light/dark cycle helps regulate body temperature in ectotherms. In X. laevis, nocturnal release of melatonin from the pineal complex induces pigment aggregation and skin lightening. This nocturnal blanching is initiated by a sensor (type II opsin) that triggers melatonin release when light intensity falls below a minimum threshold, and an effector (melatonin receptor) in the skin which induces pigment aggregation. The sensor/s and effector/s belong to two families of G-protein coupled rece
