Placunidae, also known as windowpane oysters, windowpane shells, and Capiz shells, are a taxonomic family of saltwater clams, marine bivalve mollusks which are related to oysters and scallops.
This family is best known for the shells of the species Placuna placenta, which are translucent, and are commonly used in shellcraft production. In some cultures, they are cut into 2" x 2" and pressed by a 1/4" wood and are used as a form of light-admitting window.[2] This shells are a bit reflective and are even used as room movable divider (partition).
The family is closely related to the Anomiidae (saddle oysters). One of the main differences is that the Placunidae do not attach themselves to a hard surface but are instead a mud-living family.
Placunidae are suspension feeders, living on shallow, muddy-bottomed waters. They usually lie with the right valve downwards. The ligament is internal and forms a shallow V-shape.
The sexes are separate and the larval stage is free-swimming.
Species in the family Placunidae are extensively collected in the Indo-West Pacific, and are cultivated or farmed in several areas.[3]
The windowpane oysters are valued for their translucent shell. The shells were originally used as a glass substitute in glazing, but nowadays they are mainly used in the manufacture of trays, lampshades and numerous decorative items.[2]
In coastal areas the flesh is eaten.

Placunidae sunt familia marinorum molluscorum bivalvium, Ostreidas Pectinidasque cognata. Quae familia ad Anomiidas arte cognata est, sed ab eis distinguitur quod Placunidae se ad superficiem duram non adfigunt, sed potius in luto vigent.
Placunidae suspensione vescuntur, in aquis humilibus turbidisque habitantes. Eae plerumque valva dextra deorsum iacent. Ligamen internum est, quod humilem formae litterae V exemplar efficit.
Sexus sunt distincti, et larvae libere natant.
Species familiae Placunidarum in oceanis Indico Pacificoque Occidentali late petuntur, in nonnullis regionibus aquacultura alitae.[1] Testis pellucidis magnae fiunt: eae pro vitro in vitreando? olim adhibitae sunt, sed hodie in manufactura ferculorum, umbraculorum lucernarum multarumque rerum ad ornamentum adsumptarum praecipue adhibentur. Caro in regionibus litoralibus comeditur.
Haec stipula ad bivalve spectat. Amplifica, si potes! Placunidae sunt familia marinorum molluscorum bivalvium, Ostreidas Pectinidasque cognata. Quae familia ad Anomiidas arte cognata est, sed ab eis distinguitur quod Placunidae se ad superficiem duram non adfigunt, sed potius in luto vigent.
