📖 Overview

Eptatretus Ancon (Eptatretus ancon), first described by Díaz & Acero P., 2001 is a medium-sized fish in the family Myxinidae (order Myxiniformes). Adults typically reach 22.00 cm in maximum length. It inhabits marine coastal and open-ocean environments. It occurs in Deep-water waters. It feeds on a mix of small fish and invertebrates as a mid-level predator. On the IUCN Red List, it is classified as Data Deficient.

🔬 Taxonomy

🐟 Physical Description

External aperture of its last efferent gill duct and pharyngocutaneous duct separated. Gill apertures nonlinear and crowded. Lengths of efferent gill ducts unequal with anterior ones much longer with length of first about 3 times that of last. Gill apertures 6. Slime pores: prebranchial 26; branchial 0; trunk 45; tail 9; total 80. Caudal and ventral finfold not well developed. Head, body, tail and finfold uniformly light brown in alcohol; eyespots faint, gill aperture margins not pale. Ventral aorta bifurcated between the fourth and fifth gill pouches .: eel-like.

🥚 Reproduction

🐣 Oviparous 📦 Batch Spawner
Spawning Season
spring-summer
Spawn Location
Pelagic
Fertilization
External

Iteroparous . 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 .
