Coryphella monicae (Korshunova, Martynov, Bakken, Evertsen, Fletcher, Mudianta, Saito, Lundin, Schrödl & Picton, 2017)
Coryphella monicae is easily recognized by its broad dull white line on its back and its orange-red or red cerata. It is found in areas with hard ground where there are many hydrozoans.
The thread snail can grow up to 40 mm and has a semi-transparent, white, wide body. The long mouth tentacles are 1.5 times longer than those of the rhinophores, which are somewhat wrinkled. The cerata are arranged in continuous rows on their notum. They are vase-shaped with a blunt tip and an elongated, pronounced nettle sac.
The intestinal tract of the cerata is reddish-brown or orange-brown. The upper surface of the mouth tentacles and rhinophores have distinct dull white pigmentation. The top of the cerata has small white pigmented dots. On the back there is a broad, dull white line from head to tail, variable in width, often extending between the base of the cerata. The "tail" is short. The tip of the cerata has no white pigmentation.
Monica's Coryphella lives in areas with the cnidarian (hydrozoa) Tubularia indivisa and is most commonly found at depths between 20 and 30 m. It feeds on hydrozoans of the genus Eudendrium, which sit on the stem of Tubularia or on the ground.
The spawn is deposited in a tight spiral. Reproduction takes place in February - May.
Coryphella monicae was described by Gülen in Sognefjord, Norway in 2017, which is also referred to by the synonym "Gulenia".
The species name "monicae": Named after Monica Bakkeli, owner and operator of the Gülen diving center and initiator of the annual "slug safari".
Coryphella monicae is visually almost identical to Coryphella orjani. Coryphella monicae has a narrower body and a shorter cerata than Coryphella orjani. Identification should be confirmed with DNA barcoding.
