生態學
海洋 底中水層性; 非遷移的; 深度上下限 16 - 1000 m (Ref. 1371), usually 90 - 700 m (Ref. 1371). 亞熱帶的; 59°N - 24°N, 81°W - 42°W (Ref. 1371)
Northwest Atlantic: Newfoundland, Canada to the northern end of the Straits of Florida, USA. A species reported from the northeastern Atlantic (Ref. 6321) should be reexamined. Report of specimen from the Azores and records from the Gulf of Mexico and West Indies (Ref. 6322) probably refer to other species.
西北大西洋: 加拿大紐芬蘭到佛羅里達海峽，美國的北方末端。 一個種記錄自了東北方的大西洋 (參考文獻 6321) 應該被重考。 標本從亞速群島的報告而且來自墨西哥灣與西印度群島 (參考文獻 6322) 的紀錄可能指的是其他的種。
大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 40.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 1371); 最大年齡: 11 年 (Ref. 40732)
背棘 (總數): 2; 臀棘 0. Snout pointed; naked area on snout confined to median-ventral strip, otherwise head surfaces completely scaled. Spinules on scales slender, conical to lanceolate, arranged in convergent rows. Color when fresh gray with violet hue on trunk and lower jaw; silvery reflections on gill cover, parts of the suborbital, and trunk and tail below the lateral line; pelvic fins and membrane between spinous dorsal ray and first segmented ray black; pectoral and median fins otherwise dusky; oral and branchial cavities mostly black.
吻端尖的; 在吻上的裸露區侷限於腹面中央的長條了, 否則頭部表面鱗片覆蓋完整。 在鱗片上的小刺細長的, 錐形到矛尖形的, 排列成趨集於一點的列。 顏色新鮮時在軀幹與下頜上灰色的有紫羅蘭色的色; 在側線之下的在鰓蓋，眶下骨的部份與軀幹與尾部上的銀色的反光; 在刺狀的背鰭鰭條與第一段的鰭條黑色之間的腹鰭與薄膜; 胸鰭與中央的鰭不一樣地暗色的; 口腔與鰓室大部份黑色。
Benthic, reported as deep as 2295m (Ref. 58426). Taken much shallower in areas with cold surface waters. Feeds primarily on euphausiids, amphipods, and polychaetes, although a 200 mm individual had many copepods in its stomach (Ref. 1371).
底棲的.(參考文獻 58426) 採自較淺處在有寒冷的水表面的區域中。 主要吃磷蝦，片腳類動物與多毛類動物, 雖然一個 200 mm 個體有許多橈腳類的動物在它的胃裡。 (參考文獻 1371)
