Recorded distribution in Britain and IrelandThis uncommon nudibranch has recently been recorded in large numbers in the south and west coasts of the British Isles. It has also been recorded as far north as St. Kilda.
HabitatCrimora papillata is a sublittoral species probably found at depths over 30 meters on the bryozoans Chartella papyracea, Flustra foliacea and Securiflustra securifrons.
- Translucent white to yellow body up to 3.5 cm in length.
- Covered in distinctive yellow-orange tubercles.
- The tips of the tubercles are branched or arborescent.
- The lamellate rhinophores, oral tentacles and gills are tipped with yellow-orange pigmentation.
Additional informationCrimora papillata feeds on bryozoans, primarily Chartella papyracea, but also Flustra foliacea or Securiflustra securifrons. Until 1972, this species was regarded as one of the rarest nudibranchs in the British Isles (Thompson, 1988).
The spawn of this species is bright yellow (Rudman, 2002c) and its penis bears numerous hooked spines (Thompson, 1988).
