This is a true Cribrinopsis fernaldi known from NE Pacific where it has been often confused with another common species, recently described as Cribrinopsis rubens. Cribrinopsis fernaldi, in contrast with Cribrinopsis rubens, has uniformly white column and prefers muddy habitats. Cribrinopsis fernaldi is large, conspicuous anemone, reaching 15 cm in column diameter. The tentacles are long, up to 20 cm, with veined surface. The cylindrical column is attached to small rocks and cobble, usually imbedded in silty or mud substrates. The column has numerous verrucae, better developed on the upper half of column. The verrucae are not prominent, become inflated and clearly visible on the partially contracted specimens, not adhesive, are marked by white pigment and have at their summit a thin mesogloea which looks like a transparent spot or depression in the photographs. There is a ring of prominent marginal spherules. Colour is fairly consistent. The oral disc is pinkish, with reddish radial lines. The tentacles have distinct rose-coloured vein-like or zig-zag pattern on pale-rose semitransparent background. In some specimens the tentacles have vaguely yellowish tips.
