Biology:Operculum papillare
From HandWiki
The operculum papillare is the iris found in the eyes of elasmobranchs (skates, sharks and rays).[1] It can undergo pupillary light reflex to such an extent that the eye is essentially shut off. It is sometimes called the golden iris because of the shine it sometimes causes.
