Hagfish
Hagfish, of the class Myxini (also known as Hyperotreti) and order Myxiniformes , are eel-shaped, slime-producing marine fish (occasionally called slime eels). They are the only known living animals that have a skull but no vertebral column, although hagfish do have rudimentary vertebrae. Along with lampreys, hagfish are jawless; the two form the sister group to jawed vertebrates, and living hagfish remain similar to hagfish from around 300 million years ago. The classification of hagfish had been controversial. The issue was whether the hagfish was a degenerate type of vertebrate-fish that through evolution had lost its vertebrae (the original scheme) and was most closely related to lampreys, or whether hagfish represent a stage that precedes the evolution of the vertebral column (the alternative scheme) as is the case with lancelets. Recent DNA evidence has supported the original scheme. The original scheme groups hagfish and lampreys together as cyclostomes (or histori ...

Eptatretus Burgeri
The inshore hagfish (''Eptatretus burgeri'') is a hagfish found in the Northwest Pacific, from the Sea of Japan and across eastern Japan to Taiwan. It has six pairs of gill pouches and gill apertures. These hagfish are found in the sublittoral zone. 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. The hide of this hagfish is processed into "eel skin" in Korea and exported worldwide. As food In most countries hagfish are usually not eaten, but this particular species is valued as food in the Korean Peninsula and among the Koreans in Japan. It is also enjoyed by Japanese as a local delicacy in some regions, particularly Nagasaki and Niigata Prefectures. It is known as '' ...
