Spiny Sucker Eel, Lipogenys gillii Goode & Bean 1895

More Info


Distribution

Off Nobbys Head, New South Wales, south to the Pedra Branca Seamount area, south of Tasmania. Elsewhere, the species occurs off Japan, the Hawaiian Islands, the Atlantic, and southwestern Pacific.

Features

Dorsal fin VI-VIII, 4-5; Anal fin spines 44-58, soft rays 67-88; Vertebrae 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. 

Feeding

Reportedly feeds 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

Etymology

The species is named in honour of Theodore Gill, who first named the genus Lipogenys in an unpublished manuscript.
