Notacanthidae (Deep-sea spiny eels)
Etymology: Lipogenys: Greek, lipos = fat + Greek, geny, -yos = face, jaw (Ref. 45335).
Eponymy: Professor Theodore Nicholas Gill (1837–1914) was an American ichthyologist, malacologist, mammologist and librarian, a zoologist at George Washington University and associated with the Smithsonian Institution for more than half a century. [...] (Ref. 128868), visit book page.

検索表 | 形態学 | 形態計測学
背面の脊椎 (合計) : 6 - 8; 背鰭 (合計) : 4 - 5; 肛門の骨: 44 - 58; 臀鰭: 67 - 88; 脊つい: 228 - 234. Tail slender and tapering to a point. Mouth inferior, small and sucker-like; upper lip with thick, pleated folds; posterior end of maxilla bent sharply downward, forming a flap-like structure; fleshy papillae on snout bordering upper lip. Teeth absent. Dorsal fin short-based, located above anus, the first 4-6 rays hard and spinous, increasing in length from front to back, the remainder soft and segmented, membrane connecting all rays except for first I-III spines. Anal fin long, extending from just behind anus to tip of tail, anterior rays spinous, posterior rays segmented, the transition gradual. Caudal fin absent (Ref. 11041). Light brown, lining of gill chamber and rim of opercular branchiostegal flap dark brown, mouth and lining of buccal cavity light yellowish tan (Ref. 37108).
Body shape (shape guide): elongated; Cross section: circular.
Feed mostly on organic material contained in bottom sediment drawn up by the sucker-like mouth [RF doubts this is a detritus feeder; the elaborate mouth without teeth looks like a specialization for extracting soft-bodied benthic invertebrates out of the ground; also, there are no gill rakers to filter detritus (Ref. 50674)]. No obvious sexual dimorphism; a female of 37.5 cm SL was still immature (Ref. 50674).
