Cecina (gastropod) explained

Cecina is a genus of sea snails which have a gill and an operculum, gastropod mollusks or micromollusks in the family Pomatiopsidae.

They live in shallow waters in littoral and supralittoral habitats.^[1]

Distribution

The distribution of the genus Cecina includes the Sea of Japan in Primorsky Krai, Russia,^[1] Japan and Washington state, USA.^[2]

Species

In 1861, Arthur Adams described the genus Cecina as a monotypic genus with Cecina manchurica as the only species. The current classification of Cecina follows Davis (1979)^[3] and other authors.^[4]

In 1996, Larisa A. Prozorova reviewed the genus, described 6 new species of Cecina and re-established Cecina tatarica as a separate species.^{[1] [5]}

There are eight^[1] species within the genus Cecina:

• Cecina alta Prozorova, 1996^{[5] [6]}
• Cecina elenae Prozorova, 1996^[5]
• Cecina kunashirica Prozorova, 1996^[5]
• Cecina manchurica A. Adams, 1861^{[1] [5] [7]} - type species^[3]
• Cecina murshudovi Prozorova, 1996^[5]
• Cecina satrae Prozorova, 1996^[5]
• Cecina scarlatoi Prozorova, 1996^{[1] [5]}
• Cecina tatarica (Schrenck, 1867)^{[1] [5]}
