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.{{FishBase|Eptatretus|burgeri|id=8712}} 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.{{cite journal|pmid=17691082|year=2007|last1=Holland|first1=ND|title=Hagfish embryos again: The end of a long drought|volume=29|issue=9|pages=833–6|doi=10.1002/bies.20620|journal=BioEssays}}
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 bùshì nián mángmán ({{lang|zh|布氏黏盲鰻}}){{cite web|url=https://taibnet.sinica.edu.tw/chi/taibnet_species_detail.php?name_code=383226 |title=Eptatretus burgeri|website=Checklist of Taiwanese Species at the Catalogue of Life in Taiwan|publisher=Biodiversity Research Center, Academia Sinica|location=Taiwan|access-date=25 July 2021|lang=zh}} and púshì nián mángmán ({{lang|zh|蒲氏黏盲鰻}}){{cite web| url =http://www.bioinfo.cn/db05/BjdwSpecies.php?action=view&id=5073| title =蒲氏盲鳗| work =中国动物物种编目数据库| publisher =中国科学院微生物研究所| author =中国科学院动物研究所| accessdate =2021-07-25|url-status= dead| archiveurl =https://web.archive.org/web/20160305040415/http://www.bioinfo.cn/db05/BjdwSpecies.php?action=view&id=5073| archivedate =2016-03-05}} among other names in Mandarin Chinese, kkomjangeo ({{lang|ko|꼼장어}}) or meokjangeo ({{lang|ko|먹장어}}) in Korean,{{Cite GBIF|id=2498609|taxon=Eptatretus burgeri (Girard, 1855)}} and nuta-unagi ({{lang|ja|ヌタウナギ}}) in Japanese.
As with all hagfish, the inshore hagfish produces slime when agitated. This is obtained by placing a live inshore hagfish into a container and knocking the container with a stick.
