Description

''Cribrinopsis fernaldi'' is a large anemone that can be crimson red, orange or white. This species has zigzag transverse lines on its tentacles, white tubercles on its column, and spherules just below the tentacles. These spherules can be especially hard to see as they are often withdrawn. The column is up to in diameter and around high. The oral disk has yellow or pink lines radiating from the mouth to the margin. These can be difficult to see in dark red individuals.Kozloff, Eugene N. (1987).

'' is another common large red anemone with lines radiating on the oral disk from the mouth towards the margin. ''U. crassicornis'' has transverse bands on the tentacles, but these are broad and straight, unlike ''C. fernaldi'', which has thin zigzag transverse stripes. Additionally, the bands on ''U. crassicornis'' are fainter, appearing to be internal. In contrast, the bands on ''C. fernaldi'' appear to be superficial and are much bolder. ''U. crassicornis'' has column that is green mottled with red and ''C. fernaldi'' has a column that is red with regular white spots on tubercles.

''C. fernaldi'' occurs from the Gulf of Alaska to Washington. It is strictly subtidal to depth.Gotshall, Daniel W. (1994). ''Guide to Marine Invertebrates: Alaska to Baja California''. Sea Challengers Publications. Paperback, 105 pp.
