|Other common names||Drummond’s facelina||Synonyms||Facelina auriculata var. curta , Facelina curta Alder & Hancock 1843, Facelina drummondi Alder & Hancock 1848, Facelina gigas Costa 1866|
Up to 5.5 cm long with a translucent white body that is tinged rose-pink, Facelina bostoniensis is the largest facelinid nudibranch in British waters. The area surrounding the mouth is typically red and the red oesophagus is visible externally behind the rhinophores. The rhinophores bear up to 30 conspicuous lamellae and are shorter than the oral tentacles, which can be half the body length. The dorsal cerata are arranged in up to 8 clusters.
Recorded distribution in Britain and IrelandFound all around the British Isles, but less common around the southeast coast of England.
Global distributionFound on both sides of the North Atlantic Ocean. In Europe from southern Norway to the Iberian Peninsula and the Mediterranean.
HabitatFound sublittorally on species of the hydroid Tubularia, or intertidally on species of the hydroid Clava
- Body translucent white, with red oral area and oesophagus.
- Oral tentacles longer than rhinophores, up to 1/2 length of body.
- Cerata arranged in up to 8 clusters.
- Cerata up to 1/3 to 1/2 body length.
The taxonomic history of Facelina bostoniensis is complicated, and was only relatively recently recognised as being conspecific with Facelina auriculata var. curta. Facelina bostoniensis has a broader body, longer cerata, which can be 1/3 to 1/2 of the body length and lacks a blue irridescent sheen distinguishing it from Facelina auriculata
