Philine auriformis
Taxonomic Group: Mollusks-Gastropods


Philine auriformis is a cephalaspidean or bubble snail, commonly known as the Tortellini Snail or the New Zealand Sea-Slug. It is native to New Zealand where it is common throughout shallow and deeper coastal waters. Introduced populations are known from along the West Coast of North America from southern California to British Columbia, Canada. This species is found in a variety of habitats from warm to cold-temperate climates. It ranges from the lower intertidal to depths as deep as 300 m and is found on soft substrates, mudflats, and eelgrass beds. In California, an increase in P. auriformis was accompanied by a decrease in the abundance of small bivalves, its prey, but the possible impacts of this sea-slug require further study.
