Species

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.

Contents

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.

Description

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.

Reproduction

The sexes are separate and the larval stage is free-swimming.

Cultural usage

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.

<i>Strombus</i> Genus of gastropods

Strombus is a genus of medium to large sea snails, marine gastropod molluscs in the family Strombidae, which comprises the true conchs and their immediate relatives.

Six species live in the greater Caribbean region, including the queen conch, Strombus gigas, and the West Indian fighting conch, Strombus pugilis. However, since 2006, many species have been assigned to discrete genera. These new genera are, however, not yet found in most textbooks and collector's guides.

The windowpane oyster is a bivalve marine mollusk in the family of Placunidae. They are edible, but valued more for their shells. The shells have been used for thousands of years as a glass substitute because of their durability and translucence. More recently, they have been used in the manufacture of decorative items such as chandeliers and lampshades; in this use, the shell is known as capiz shell (kapis). Capiz shells are also used as raw materials for glue, chalk and varnish.
