Magallana

Magallana is a genus of true oysters (family Ostreidae) containing some of the most important oysters used for food. Species in this genus have been moved from Crassostrea after it was found to be paraphyletic.

Species

Extant species are:

• Magallana angulata (Lamarck, 1819)
• Magallana ariakensis (Fujita, 1929) – Suminoe oyster
• Magallana belcheri (G. B. Sowerby II, 1871)

Genetics

The genome of Magallana gigas has been recently sequenced revealing an extensive set of genes that enable it to cope with environmental stresses.
