Eastern Atlantic: northern Norway and Iceland, Skagerrak and Kattegat south to Morocco including western Mediterranean (some isolated records from eastern part), Azores and Madeira Islands. Records from South Africa are questionable. Reported from Oshima, Japan (FMNH 89161) (Ref. 27954).

簡短描述
檢索表 | 型態特徵 | 形態測量圖
Bathydemersal to benthopelagic generally between 300 and 500 m depth. Found in the upper continental slope. Usually found in deeper waters in southern latitudes, while making a summer inshore migration up to 40-100 m in the northern areas. Sluggish, usually occurring in small groups. Feeds mainly on bottom-living invertebrates. The single dorsal spine is sharp and pointed, and although only mildly venomous can inflict a painful wound. Oviparous. Males have a clasper on the forehead that is probably used to hold on to the female during copulation. Egg capsules are about 17 cm long; young look alike adults and hatch when 10 cm long. Common by-catch when trawling for shrimps in the North Sea or Skaggerak.
對大洋底棲性魚種的深海底棲性通常在 300 與 500 公尺深之間。 發現於大陸坡上層了。 南方的緯度的通常發現於較深的水域,在區域北部中當進行夏天近岸迴游向上到 40-100 公尺。 緩動性的, 通常出現在小群魚群。 主要吃底棲無脊椎動物。 單一背棘是銳利而尖的, 而且雖然只有溫和的有毒能施放令人痛苦的創傷。 卵生的。 雄姓在前額有一個鰭腳可能，那是用來在連結的時候抱住母魚。 卵鞘是大約 17 公分長; 幼魚形似成魚而且孵化當 10 公分長的。 經常被誤捕當拖網對於蝦在北海或 Skaggerak 中。

Oviparous; egg-capsules slender, club-shaped with narrow lateral membranes and a horny filament at the long pointed end, 17 cm long and 3 cm wide; deposited mainly in spring and summer. The embryos developing in about 9-12 months and hatch at 10 cm length. 東大西洋: 挪威北部與冰島，史卡基拉克海域與 Kattegat 南至摩洛哥包括地中海西部 (一些孤立的來自東部的紀錄) ，亞速群島與馬得拉群島。 來自南非的紀錄是可疑的。 記錄來自 Oshima ，日本 (FMNH 89161)了。 (參考文獻 27954)
