Pinctada capensis

Pinctada capensis (Sowerby, 1872)

Distinguishing Characteristics

The shells of P. capensis look very similar to Pteria shells. They have a longer shape that is slightly deformed. When both halves are open, the silhouette of the shell resembles a “C” shape. The luster of the inner shell is dull, making the nacre appear milky white. Sometimes a yellowish grey/bluish tint is possible. Shells can measure up to 10 cm in length.

Ecology and Habitat

P. capensis is only found on the coast of East and South Africa. The banks stretch along the coast of Mozambique from the Island of Bazurto to False Bay, near Cape Town in South Africa.

P. capensis in Pearls

Although pearls are rarely found, the P. capensis is known as “The Pearl Oyster” in South Africa, and are one of the most important oysters on the South African coast.Their pearls are usually non-uniform in shape and less lustrous than commercial pearls.
