Eptatretus bischoffii is a common
demersal, non-migratory, marine habitat with its depth range between 8–50 m. It can survive in only temperate zones. These organisms are found in the South Pacific, mainly, Chile
. It is harmless to humans.
The mode of reproduction in this kind of organism is
functional hermaphrodite
. However, hermaphroditism being characterised as functional needs to be validated by more reproduction studies.
The eggs develop in the demersal areas. The shape of the eggs are elongated. The egg contains a single micropylar opening located at the animal pole. It is situated at the bottom of a micropylar cup which lies between the anchor filaments. The single filaments are 3.2–4.9 millimetres (0.13–0.19 in) long and have an anchor-shaped apical end. The number of filaments varies around 50 but is always smaller on the vegetative end. On both ends of laid eggs, the filaments are enveloped by a gel-like matrix intertwined with large cytoskeletal biopolymers (keratin-like intermediate filaments) of possible holocrine origin.
