Color of live specimens pinkish red with whitish head anterior to first slime pore; whitish middorsal stripe extending from caudal finfold to about over gill apertures. Six pairs of gill pouches; a 2-cusp multicusp on both anterior and posterior sets of cusps, total cusps 38-44. Pores: prebranchial 28-38; trunk 61-73; tail 11-13; total 101-119. Ventral finfold 4-6 mm high.
活體的顏色略帶桃色的紅色有微白色的頭部第一個位於黏液孔前; 從尾鰭的鰭褶延伸的微白色的背面中央的斑紋到大約鰓孔上面。 六對的鰓囊; 在兩者的前列與後列的尖頭，總尖頭 38-44 上的一個 2 尖頭的多尖頭. 孔: 前鰓 28-38; 軀幹 61-73; 尾部 11-13; 總計 101-119 。 腹面鰭褶高度地的 4-6 mm。
Of 30 specimens, 26 were females, 3 males, 1 hermaphrodite. Four females had large eggs about 20 x 6 mm, but none of the eggs with encapsulated anchor filaments. The species lives on the continental slope.
30件標本, 26 是雌性， 3個雄性， 1個雌雄同體。 四個雌性有.大的卵大約 20 x 6 mm, 但是沒有那卵有嵌入內部的錨狀絲。 此魚種靠大陸斜坡生活。
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚
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 ).西南大西洋: 巴西。
