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.
The first stage in an oyster’s life cycle is the free-swimming larval stage. After about three weeks, the larva attaches to a hard substrate—surface area to attach to—such as prop roots, dock pilings, natural rock, and other oysters becoming an oyster spat—oysters that have just settled to the bottom.

The windowpane oyster (Placuna placenta) is a bivalve marine mollusk in the family of Placunidae. [1] It is edible, but valued more for its shell (and its rather small pearls). The oyster's shells have been used for thousands of years as a glass substitute because of their durability and translucence.
Oyster reef restoration projects often place the sanitized shells of dead oysters, concrete, or limestone pieces on a soft bottom to encourage oyster spat settlement. [10] Restoration of intertidal eastern oyster reefs can match natural densities of oysters and mud crabs , and recover oyster stability in about 6 years. [ 18 ]

Tabby is a type of concrete made by burning oyster shells to create lime, then mixing it with water, sand, ash and broken oyster shells. [1] Tabby was used by early Spanish settlers in present-day Florida, then by British colonists primarily in coastal South Carolina and Georgia . [ 1 ]
