Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm ?, range 25 - ? cm
Max length : 95.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 119696); common length : 30.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 35388); common length :40 cm TL (female)
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.
无颌的嘴 , 单一鼻的孔, 只有一个成对的鳃孔, 没有鳃盖或皮肤的覆盖摺层。 浅灰色或红褐色的上方, 单色的。 变化颜色与海底的颜色一致。
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.
栖息于泥底部了在哪里它们藏在泥中。 黏液被用来防卫。 主要捕食不特定鱼种的死而垂死鱼利用穿孔进入身体与啃食内脏与肌肉组织。 主要夜行。 它的卵是数目很少大约 19-30 与大的 (20-25 mm), 角状的外型突起在每个末端有一个锚顶端丝状突起的群。
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).東北大西洋: 莫曼斯克到地中海。 不存在於地中海東部與黑海。 在東北大西洋的唯一盲鰻。
