Species of bivalve
Theora lubrica is a bivalve mollusc endemic to the Northwest Pacific, including northern Japan, southern Russia and Hong Kong.[2] It was introduced into harbours around the North Island of New Zealand around 1972, and has since spread to the upper South Island.[3][4] It has also been introduced to California, Australia, the Mediterranean Sea and the Atlantic Sea.[2]
Theora lubrica is a deposit feeder with a thin, nearly transparent shell.[4] Theora lubrica is mud-tolerant and lives in burrows on subtidal and lower intertidal flats.[4][2] Theora lubrica is considered a pollution-indicator species as it is tolerant of pollution and is often found to be abundant in polluted sediments.[4][2]
