背面の脊椎 (合計): 0; 背鰭 (合計): 0; 肛門の骨 0; 臀鰭: 0. No true fins - one dorsal finfold, far back, median, very low, continuous with caudal; caudal broad, rounded; ventral finfold very low, origin somewhat posterior to last gill pore, extending to anus (Ref. 6885).

生物学     用語集 (例 epibenthic)

Inhabits fine silt and clay bottoms (Ref. 6885). Enters large fishes by way of the mouth and anus and feed on its viscera and muscles (Ref. 6885). May greatly diminish catches taken with fixed gears (Ref. 6885). Produces mucilaginous slime when harassed (Ref. 6885). Probably exhibits hermaphroditism (Ref. 56947). Due to its primitive metabolism it is collected for research purposes (Ref. 6885).

Life cycle and mating behavior 成熟 | 繁殖 | 放精 | | 生産力 | 幼生

Copulatory organ absent (Ref. 51361). Presence of bisexual juvenile gonad, requires further investigation regarding hermaphroditism (Ref. 56947). In one study (Ref. 40710), hermaphroditism is exhibited by only 0.2% of the individuals studied.
