Myxinidae (Hagfishes) > Rubicundinae
Etymology: Rubicundus: Latin for red or ruddy, referring to reddish coloration of all species (See ETYFish); eos: After Eos, goddess of morning-glow, referring to its pink color (See ETYFish).
Eponymy: Eos in Greek mythology was the goddess of the dawn. In zoology, her name is generally applied to species that have ‘rosy’ coloration, sometimes combined with orange or yellowish hues that might be reminiscent of a sunrise. (Ref. 128868), visit book page.

Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva
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 ).
