Description
A small flabellinid reaching about 26 mm in length. The body is translucent white, with an orange-tinted visceral mass visible through the body wall. Each ceras shows a red digestive gland through its wall and ends in a white tip. A single fine white line runs along the midline of the tail. The rhinophores and oral tentacles are smooth, translucent white like the body, with fine white speckling along the distal half. Externally distinguished from Coryphella athadona by the absence of a white longitudinal line on the dorsum.Distribution
The type locality is Oshoro Bay, Hokkaido, Japan, based on material described by Hirano & Kuzirian (1991). Subsequent records are concentrated in cold-temperate Japanese waters.Etymology
The specific epithet amabilis is Latin for "lovely" or "lovable".References
