Winged
oysters
Family Pteriidae
updated
May 2020
Where
seen? These strangely shaped clams grow attached to other animals like sea
fans and sponges, as well as mangrove trees.
What are winged oysters? Winged
oysters belong to the Family Pteriidae.
Features: 1-8cm. Unlike
other bivalves, they have comb-like teeth in the hinge, a feature
of this family. They stick to hard surfaces by byssus threads.
Human uses: Some species are collected
for food by coastal populations and used as a substitute for true
oysters. The oysters that produce commercial precious pearls belong
to this family, but those seen on our shores do not produce pearls. |
