Small to medium sized aeolid nudibranch found generally
on hydroids. The base colour is violet with orange-red
digestive gland tributaries in the cerata and can be
superficially confused with Flabellina affinis, which
inhabits the same habitat. Common in winter months.
Propodial tentacles: Present, violet with white line near
anterior edge and white tips, slightly recurved. Oral tentacles: Present, white tipped, longer than the
rhinophores. Rhinophores: Violet with white tips, rugose but without
distinct lamellae. Cerata: Thin, distinctly orange red to red with white tip. Foot: Pale violet occasionally with diffused white pigment
near the anterior area.
Size range: 5-20mm. Common.
Specific characteristics: This species is easy to
distinguish from related species by its colouration, but
may be confused with Flabellina affinis. The latter species
has lamellate rhinophores and a subterminal purple ring on
