This species is one of the few Corallimorph cnidarians found in our area, and the only one in Kozloff's key. Corallimorphs are not true anemones. The most obvious difference is that their tentacles end in knobs (club-tipped tentacles), as are visible in the picture above. The tentacles are not fully retractile, and are usually white. Corallimorphs are also very similar to corals in some other characters, but lack the hard coral skeleton. This species is often found in groups, with individuals up to 2 cm long or even more (photo) (average height and diameter is 1 cm). May be colored red, crimson, pink, purple, pale blue, lavender, brown, orange, buff, or nearly white.
