How to Distinguish from Similar Species: Both A. elegantissima and A. xanthogrammica have tubercles and symbionts all the way to the bottom of the column, and live on rock or protrude through only a little sand. Some sources say that A. artemisia does not have symbiotic algae.
Geographical Range: Alaska to southern California. Very common around Juneau, Alaska.
Depth Range: Low intertidal and subtidal to about 30 meters
Habitat: Open coast and (more often) in protected bays, prefers habitats with rocks or cobble buried in sand.

that they do not even though they may sometimes be green in
color. In British Columbia this species has been observed
feeding on spawned herring eggs.
