- Windowpane oysters are distinctive in having extremely thin, paper-like shells that
are translucent. Among them are the kapis shells often used in the lanterns of
Asian manufacture. A hole through the edge of the lower shell is often visible, through
which the byssus attaches to rocky surfaces. The mantle grows to eventually surround the
byssus, forming a hole usually near the shell edge.
- The oyster is astringently bitter and not good to eat. Its main value lies in raw material for the manufacure of animal glue, chalk, shellac, soldering lead, and paint, as well as decorative objects. Shells larger than 7.5 cm are of highest value.
- Ephihippium is synonymous with Placuna.
