生态学
海洋 底中水层性; 非迁移的; 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 / 年龄
Maturity: Lm ? range ? - ? cm
Max length : 40.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 1371); 最大年龄: 11 年 (Ref. 40732)
背棘 (总数) : 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; 在吻上的裸露区局限于腹面中央的长条了, 否则头部表面鳞片覆盖完整。 在鳞片上的小刺细长的, 锥形到矛尖形的, 排列成趋集于一点的列。 颜色新鲜时在躯干与下颌上灰色的有紫罗兰色的色; 在侧线之下的在鳃盖，眶下骨的部份与躯干与尾部上的银色的反光; 在刺状的背鳍鳍条与第一段的鳍条黑色之间的腹鳍与薄膜; 胸鳍与中央的鳍不一样地暗色的; 口腔与鳃室大部份黑色。
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).
采自较浅处在有寒冷的水表面的区域中。 主要吃磷虾，片脚类动物与多毛类动物, 虽然一个 200 mm 个体有许多桡脚类的动物在它的胃里。
