How to Distinguish from Similar Species: Urticina crassicornis also may have a red column but it is common intertidally, usually has transverse bands on its tentacles, and the column often has olive green blotches.
Geographical Range: Alaska to La Jolla, CA
Depth Range: Nearly always subtidal
Habitat: Usually on a rocky prominence where there is a fair amount of current.
Biology/Natural History: This species actually captures shrimp and small fish. One fish species, however, the painted greenling (Oxylebius pictus), has been observed lying unharmed in this anemone much as clownfish do in tropical anemones.

This species can be found on rocky prominences subtidally off Sares Head. It is unusual to find it in a deep tidepool such as the individual in the picture above.
