			Source:
			"Melanopsin (OPN4) is the most well-characterized opsin involved in circadian physiology in mammals. Interestingly, the opn4 gene is duplicated in some non-mammalian vertebrates (opn4 and opn4b; also referred to as opn4m for mammalian and opn4x for Xenopus) and is expressed in the pineal complex of amphibians, reptiles, and birds [2, 18-20]."
