Snout with a pair of strong spiny hooks; numerous barbels on branchiostegal membranes. Dorsal plates 31-34 (Ref. 232). Spiny and soft dorsal fins almost fused.

碟的不成對胸部列不存在，但是成對的碟列覆蓋整個的胸部。 吻部有一對強的刺狀鉤; 很多的觸鬚在鰓蓋薄膜上。 背部的碟 31-34.(參考文獻 232) 刺狀與軟的背鰭幾乎融合了。 沒有在頭部的後部部份上的棘.(參考文獻 35388)
Inhabits inshore waters, deeper waters in winter in Skaggerak, preferring sandy bottoms, rarely with stones. Maximum depth reported at 270 m (Ref. 28197). Temp. range: 4.0-8.0 °C. Feeds on bottom crustaceans and polychaetes. Matures after about 1 year; a few spawning in the second year (Ref. 722). The eggs are laid in seaweed (Ref. 9900). Spawns in February - April, female laying 2,500-3,000 yellow eggs with a diameter of 2 mm. Period of development is very long and 6-8 mm long pelagic larvae hatch after 10-11 months (Ref. 35388).
棲息於近岸水域,較深的水域冬天時在 Skaggerak, 偏愛砂質底部, 很少有石頭。 最大的深度在 270 公尺報告。 (參考文獻 28197) 溫度範圍: 4.0-8.0 ° C. 吃底部甲殼動物與多毛類動物。 在大約 1 年之後成熟; 一些在第二年產卵.(參考文獻 722) 卵在海草中生產。 (參考文獻 9900) 產卵在二月 -四月, 母魚產下 2,500-3,000 黃色卵有 2 mm 的直徑。 發育期非常長，而且 6-8個 mm 長大洋性仔魚在 10-11 數個月之後孵化。 (參考文獻 35388)
