This species can be found in areas of muddy sand and also on rockier beaches where there are areas of gravel or shell fragments.  Normally only the oral disk and tentacles are visible with the column buried beneath the substrate.  The crown of tentacles may reach a diameter of 4 inches (10 cm.)with the tentacles colored pink, orange, green, blue, or brown and in our area often display banding.  When waters recede, the tentacles withdraw below the surface.  The upper 2/3 of the column is covered by warty looking tubercles but the lower 1/3rd is smooth distinguishing it from Anthopleura elegantissima (the aggregating anemone) which has warty tubercles the full length of its column.  The column of the moonglow anemone may extend to a length of 8 inches in order to reach the surface.  The pedal disk is anchored to rock or another solid object under the surface of the substrate. This species is found from the middle intertidal zone to a depth of 100 feet.  Other common names include the burrowing anemone, buried moonglow anemone, beach sand anemone, and buried green anemone.
