How to Distinguish from Similar Species: Stomphia didemon grows larger and has a cream to orange column.
Note: This species looks different from photos of Stomphia coccinea from the North Atlantic. I think it is likely a different species.
Geographical Range: Widespread in temperate and arctic regions of northern hemisphere; including Pacific and Atlantic
Habitat: We found it on a bottom of sand with shelly hash
Biology/Natural History: This anemone is usually attached to shells of the horse mussel, Modiolus modiolus. The anemone above was originally attached to a mussel shell but has moved to a scallop shell. This species will detach and swim away from predators such as the leather star Dermasterias imbricata.
