Philine pruinosa
(Clark, 1827)

Superfamily: PHILINOIDEA
Family: Philinidae


Known from NE Atlantic from Norway to the Mediterranean


Upper: Living animal. Egersund, 25 metres, Norway, Norwegian Sea, 15. July 2006, Rocks and shell sand. Length: Less than 1 cm. Photographer: Erling Svensen.
Lower: Drawings of shell and living animal from Norway - from Sars, 1878 [Pilsbry, 1896:  Pl.4 figs 74-78]

Little is known of the living animal but previous information summarised by Thompson (1976). From that  we know that the posterior shield has a deep posterior sinus, and the parapodia are relativley small. Form Erling Svensen's photos it would seem the animal is translucent with fine white specks all over the body, and an opaque white border to the edge of the parapodia, the head shield and posterior shield.   Some authors place this species in the genus Laona, but at this stage in our knowledge of the philinids there are not good grounds to try subdividing them into separate genera.
