This is Facelina Auriculata, it looks like Facelina Bostoniensis but is more colourful, eventhoug coluor doesnt say much with nudibranches. We had a lot of Facelina Auriculata in 2009 in Zeeland.See the link to the site of Bernard Picton, the european nudibranch secialist

Facelina auriculata (O F Müller, 1776)
--------------------------------------------------------------------------------
Description: When fully grown this nudibranch may reach 38mm in length. The ground colour is translucent white and there is a rose coloured hue around the mouth. The animal's red oesophagus is visible, just behind the rhinophores. There is an iridescent blue sheen on the head and ceratal surfaces that is characteristic of the species, but better developed in animals from deeper water. The oral tentacles are very long and the rhinophores are annulate. There are streaks of white pigment on both sets of tentacles. The cerata are also streaked with white, as is the tail of the animal.
Habitat: Known to feed on several hydroid species, but has mainly been found on Obelia geniculata on kelp fronds and on Tubularia. Found under boulders on shore as well as in the sublittoral.
Distribution: Recorded from all around the British Isles and from Norway to the Mediterranean.
Key Identification Features:
Propodial tentacles, long oral tentacles and annulate rhinophores present.
Foot narrow, cerata short, in distinct bunches, long narrow tail.
Cerata with red digestive gland and iridescent blue surface colour.

Hallo Bettina,das Fragezeichen kannst Du getrost wegnehmen. Es ist eine Violette Weissspitzen-Fadenschnecke oder eben wie Du schon richtig geschrieben hast eine Coryphella pedata.
Da ist Dir wieder ein sehr schönes und detailreiches Bild gelungen. Freut mich soetwas hier zu sehen.
Lieben Gruß aus Hamburg

Die Beschreibung der Flabellina pedata, die ich aus meinem Mittelmeerführer habe, paßt auf Deine Oosterschelde-Schnecke... ich würde also sagen, ja, ist eine.LG

Das sieht mir ganz nach einer Weisspitzen - Fadenschnecke aus. Hatte sie eine Länge von 2 - 4 cm?LG, Roland
Hier ein Model aus der gleichen Familie:
