Philine orientalis
Taxonomic Group: Mollusks-Gastropods


Philine orientalis is commonly known as the Oriental Sea Slug. It is native to the Western Pacific from Russia, Japan, China, Thailand, Java and the Philippines. It has been introduced to California. Its global range spans warm to cold temperate climates where it can be found from the lower intertidal to depths of 180 m on sand, mud and eelgrass beds. This species is a significant predator on small bivalve species in its introduced range, but its potential impacts require further study.
