Giant clams show brilliant coloration on the mantle. The color comes from iridophores which are distributed in the mesenchyme. Each iridophore contains thin reflecting platelets which are aligned uniformly in rows. The platelet is bound with a membrane and has a fine substructure with a 7 nm lattice. A fiat cistern intervenes two neighbouring platelets to keep the interspace constant. In developing iridoblast, the reflecting platelets are formed in a confined area around the nucleus. Various types of vacuoles representing transitional froms from the ER to a mature reflecting platelet are seen in the area. Golgi vesicles are involved in the platelet formation. They are incorporated onto the vacuolar membrane while accumulation of the dense reflecting substance takes place in the vacuolar lumen. The dense substance is condensed in the vacuoles. The vacuoles are then fashioned into thin rectangular platelets and aligned in rows to form an alternating reflecting surface. The intervening cistern is formed from vesicles which fuse with one another to become a flat, thin cistern.
