They live usually buried in the bottom mud and migrate into deeper water to spawn.

The inshore hagfish is the only member of the Myxinidae family having a seasonal reproductive cycle.

Generally very little is known about hagfish reproduction and embryos are difficult to obtain for study, although laboratory breeding of Eptatretus burgeri has succeeded.

[5] The hide of this hagfish is processed into "eel skin" in Korea and exported worldwide.

It is also enjoyed by Japanese as a local delicacy in some regions, particularly Nagasaki and Niigata Prefectures.
