iridocyten.

/ˈʌɪərɪdəʊsʌɪt/

Etymology: < French iridocyte (G. Pouchet 1876, in Jrnl. de l'Anat. & de la Physiol. XII. 45), < Greek ἰριδ- , iris n. + κύτος a hollow, cell.

Zoology.

A cell which refracts light to cause iridescence, found in the skin of fishes, cephalopods, and certain other animals.
