Porphyrins produce uniquely ephemeral animal colouration: a possible signal of virginity.

Scientific reports - 15 Dec 2016

Galván Ismael, Camarero Pablo R, Mateo Rafael, Negro Juan J

Abstract excerpt

Colours that underlie animal pigmentation can either be permanent or renewable in the short term. Here we describe the discovery of a conspicuous salmon-pink colouration in the base of bustard feathers and down that has never been reported because of its extraordinarily brief expression. HPLC analyses indicated that its constituent pigments are coproporphyrin III and protoporphyrin IX, which are prone to...
