Clanculus ater
Taxonomic Group: Mollusks-Gastropods


Clanculus ater is a small top shell, which inhabits rocky intertidal habitats. It is native to Japan, India, and the Philippines. Ten specimens were found in Queen Charlotte Sound, British Columbia, Canada in 1964, but no individuals have been reported since. There are no other introduced locations. This species is found in warm temperate-tropical locations, so temperatures in British Columbia may be too cold for it to survive.

* This species is not currently established in North America.
