Body (excluding appendages)
Up to 9 mm long. Translucent whitish epidermis [image3]. Tinted yellowish by microscopic translucent surface frosting , most noticeable on large specimens. Viscera show coral pink or orange on large specimens . Surface has many purple-red freckles and streaks  on specimens of 5 mm and longer, but few on 2 mm juveniles .
Contractile; can be blunt club shape  or extended and slender . Up to seven each side of body . Can be held to expose or conceal  the dorsum. Posterior ceras often tiny and concealed by overhanging adjacent one . No cnidosacs at tips. Epithelium translucent whitish , can be tinted yellowish  on large specimens, revealing orange-red , pink-red or, on 2mm juveniles, pink-white  internal digestive gland which extends to base of apical tubercle. Colour of digestive gland may reflect diet; orange-red from Garveia nutans, pink-red from Sarsia exima (EML). Each ceras has up to five concentric rings of tubercles and an apical tubercle.
Most tubercles have a large subepidermal red terminal spheroid , but it is often missing on more than half of the apical tubercles . Tubercles also have many white subepidermal bodies, most noticeably in the apical tubercle where the digestive gland does not penetrate .
No surface pigment, but some basal subepidermal red-purple mottling inside the inner (mesial) face .
Smooth, translucent white , delicately tinted yellowish  on some larger specimens, with some white surface pigment spots. Arise from a translucent white, sometimes yellow tinted, basal sheath with dilated smooth rim.
No oral tentacles, but front margin expanded laterally into lobes . Head crest runs forwards from each rhinophore .
Sole white, or may be orange on larger specimens feeding on Garveia nutans. No propodial expansion .
