Saccostrea glomerata, is an oyster species belonging to the family Ostreidae. It is endemic to Australia and New Zealand. In Australia, it is known as the Sydney rock oyster and is commercially farmed. In New Zealand, where the species is not farmed, it is known as the New Zealand rock oyster or Auckland oyster. The species is closely related to Saccostrea cucullata, the hooded oyster, which is common on Indo-Pacific rocky shores. Sydney rock oysters are capable of tolerating a wide range of salinities (halotolerant). They are usually found in the intertidal zone to 3 m (9.8 ft) below the low-water mark. From Wikipedia
