Chalcedony has a waxy luster, and may be semitransparent or translucent. It is semitransparent, colorless with pale yellow tints and shows a vitreous luster. Young instar larva are flat, yellowish white, semitransparent and with distinct segments. The dome's ceiling contained thousands of semitransparent panes made of Lucite. Many of the species are noted for their transparent or semitransparent bodies. In 2015, researchers developed a prototype cell that used semitransparent perovskite with graphene electrodes. Dichroic glass beads incorporate a semitransparent microlayer of metal between two or more layers. Each has a semitransparent elongated body that consists of two fused segments. The body is semitransparent, creamy-white, and cylindrical. Upperside semitransparent white, sometimes slightly infuscate with a powdering of black scales. The Eastern mosquitofish is a small, light-colored fish with semitransparent fins. The shell is semiovate, thin and fragile, almost smooth, brown, semitransparent. When underwater, the semitransparent lower eyelids are generally closed, covering the eyes. Succeeding segments on either side feature a lateral series of semitransparent similar brown spines. An inherent property of semitransparent materials is absorption.
