簡短描述
型態特徵 | 形態測量圖
Seven branchiostegal rays. Head notably large and broad; preopercle and suborbital bones deep and large, opercle commensurately small; orbit small, 19%-30% HL, diameter much less than broad interorbital; snout high, slightly projecting beyond mouth. Mental barbel small, 10% or less of HL. Gill opening wide, extending forward to below hind end of maxilla; gill membranes loosely and narrowly attached to isthmus. Gill rakers usually 16-17 on inner series of 1st arch. Teeth small, close-set, in narrow tapered band on premaxilla, uniserial on dentary. Scales with numerous small, awl-shaped spinules; no reticulations on anterior field; lateral line scales absent, a series of dark papillae in their place. Vent about halfway between pelvic fin insertion and anal fin origin (usually closer to pelvic insertion), surrounded by a black, oval to teardrop-shaped naked area and preceded by a small, round dermal window of light organ between pelvic fin bases. Pyloric caeca short, 22-24. Color black to dark brown overall (Ref. 54421).
七個鰓條骨。 頭部特別地大而寬的; 前鰓蓋骨與眶下骨深的而且大的, 鰓蓋同量小; 眼窩小的,19%-30% HL, 直徑遠小於寬的眼間骨; 吻高的, 些微突出超過嘴。 神經觸鬚小的, HL 的 10% 以內。 鰓裂寬的, 在顎骨的後部末端之下向前延伸到; 鰓膜鬆弛地而且狹窄地依附於峽部了。 鰓耙通常 16-17 在內部的成列第一上成弓形彎曲。 齒小的, 靠攏在一起, 在前頜骨上的狹窄被成錐形的條紋中, 排成一列的在齒骨上。 鱗片有很多的小, 錐子-形狀的小刺; 沒有在前面的範圍上的網眼; 側線鱗片不存在, 在他們的地方中的一系列的深色乳突。 排洩孔大約在腹鰭嵌入與被黑色，淚滴的橢圓形包圍的臀鰭起源 (通常更靠近腹鰭嵌入) 之間的中點-形狀的裸露區而且前面有在腹鰭基底之間的一個發光器的小又圓皮窗。 幽門盲囊短,22-24. 色彩黑色到深褐色的整體.(參考文獻 54421)
