Jawless mouth, single nasal aperture, only a single pair of external gill openings, no operculum or covering fold of skin. Grayish or reddish brown above, either plain. Variations in color correspond to the color of the sea bottom.
Body shape (shape guide): eel-like.
無頜的嘴 , 單一鼻的孔, 只有一個成對的鰓孔, 沒有鰓蓋或皮膚的覆蓋摺層。 淺灰色或紅褐色的上方, 單色的。 變化顏色與海底的顏色一致。
Benthic with reported depths to 782 off Greenland; 960 m in Northwestern Atlantic; and 1,100 m off Norway (Ref. 119696). Found on muddy bottoms where they hide in the mud. Slime is used for defense. Feeds chiefly on dead and dying fish of varying species by boring into the body and consuming viscera and musculature. Chiefly nocturnal. Its eggs are few in number about 19-30 and large (20-25 mm), the horny shell has a cluster of anchor-tipped filaments at each end.
棲息於泥底部了在那裡它們藏在泥中。 黏液被用來防衛。 主要捕食不特定魚種的死而垂死魚利用穿孔進入身體與啃食內臟與肌肉組織。 主要夜行。 它的卵是數目很少大約 19-30 與大的 (20-25 mm), 角狀的外型突起在每個末端有一個錨頂端絲狀突起的群。

Copulatory organ absent. The gonads of hagfishes are situated in the peritoneal cavity. The ovary is found in the anterior portion of the gonad, and the testis is found in the posterior part. The animal becomes female if the cranial part of the gonad develops or male if the caudal part undergoes differentiation. If none develops, then the animal becomes sterile. If both anterior and posterior parts develop, then the animal becomes a functional hermaphrodite. However, hermaphroditism being characterised as functional needs to be validated by more reproduction studies (Ref. 51361 ). Probably breed throughout the year in deep water (Ref. 35388).北大西洋: 莫曼斯克到地中海; 格陵蘭到美國。 不存在於地中海東部與黑海。 在東北大西洋的唯一盲鰻。
