Talk:Hagfish

message: Does anyone know the Japanese name for hagfish?  How is it fished?  How it is prepared?  What is the 'eel leather' used for?  Are there potential commercial uses for the slime?  It'd be nice if someone could expand the information to include a specific section on this.
: I am not Japanese. I think very few Chinese people eat this.
: Japanese word for hagfish is "メクラウナギ"; "めくらうなぎ" or "盲鰻". 
:* メクラウナギ (mekuraunagi; in katakana)
:* めくらうなぎ (same pronounciation; written in hiragana)
:* 盲鰻 (same pronounciation; written in kanji; literally "blind" + "eel")
: I know some Japanese people eat lamprey (ヤツメウナギ).
:* ヤツメウナギ (yatsumeunagi)
:* やつめ‐うなぎ
:* 八目鰻 (literally "eight" + "eye" + "eel")
: Sometimes, they are known as "七鰓鰻" or "seven" + "gill" + "eel".
: In some areas of Japan, costal fishermen use a small boat and a small net to catch lampreys. As far as I know, they may cut the fish into short segments (like chopped sausages) and boil them in water with tofu and some vegetables to make a soup. They may also roast the fish with very thick sauce over charcoal (like roast eel; see unagi).
: During the WWII, some people eat the lamprey because it was the only meat they could get. I've never eaten this fish. I saw them eating it once on a Japanese TV show. The reporter said it's very crunchy. Many Japanese people believe lampreys are good for your eyes because of chondroitin sulfate in them. In Edo period, they let nyctalopia patients eat lampreys as a source of Vitamin A. (see: :ja:ヤツメウナギ)
: I don't know how they cook hagfish. -- Toytoy 13:05, 2 July 2006 (UTC)

replies: text: i can confirm that they are used for their leather, and are not likely eaten, mike roeMike Rowe of dirty jobsDirty Jobs just did a show on these, he told us at the end of the segment that they are shipped off to korea and used to make wallets and purses, showing us an example whilst barbecuing a few that he took with him, he tried them and didn't seem to like it as he spat it out after. however the dude behind him that was cooking them didn't seem to mind itthought I'd share :) 24.85.111.11 (talk) 22:03, 23 February 2008 (UTC)
replies: text:  We definitely eat hagfish in Korea. They’re skinned, covered in spicy sauce, and either grilled over charcoal or stir fried. They’re quite tasty, not slimy at all, like a crunchier version of eel. Not sure about this claim that the slime is used like egg whites, which sounds specious to me. I know they’re also made into fish cakes, which are pretty sticky. They might have some slime in them.-- baekjemiso 10:09, 18 April 2019 (UTC)

message: Does anyone know how hagfish reproduce? Or if it is not well known, should someone point that out? It would be nice. PhoenixSeraph 20:57, 21 March 2006 (UTC)
replies: text: They're not hermaphroditic. Male and female hagfish look exactly the same, except for reproductive structures. It's believed that hermaphroditism was acquired very recently in their evolutionary history. I'll fix this point soon. Aelwyn 15:55, 10 September 2006 (UTC)
replies: text: According to this , they have both male and female gonad, but only works per individual.  Partially but not fully functioning hermaphrodites I guess. --CrossoverManiac (talk) 20:08, 9 July 2009 (UTC)
thread_title:  Reproduction 

message: I have heard that hagfish can take chunks out of large prey by fastening on with the teeth and then passing a knot from the tail towards the head. This would be worth mentioning if anyone has evidence for it. Myopic Bookworm 11:41, 21 September 2006 (UTC)

replies: text: I need to rework the sliming and behavior and distinguish the two. There is video of them using the knot trick to get purchase to bite out chunks, for sure. It's quite scary to see six or so of the buggers all doing it at once on a mackerel carcass. So much for them not being able to get through skin! --mmbutler@gmail.com, still no account.  —Preceding unsigned comment added by 75.18.167.24 (talk) 12:00, 25 January 2009 (UTC)

message: It's not clear to me why a section of this article is entitled "Venom." Apparently hagfish are not venomous, and the contents of the section don't seem to have anything to do with venom. -75.90.166.235 (talk) 07:16, 6 January 2008 (UTC)
thread_title:  Venom? 

message: This article currently includes a drawing of Eptatretus minor, which appears to be a hagfish. However the list at Hagfish#Species, which appears to attempt to be comprehensive, does not include Eptatretus minor. Nor does the article on Eptatretus. Is "minor" another name for one of the listed species? I do see E. minor listed on FishBase, but don't know what to do from there. — Epastore (talk) 22:55, 20 February 2008 (UTC)

message: In this section it is noted that Hagfish slime is unique in that it contains threadlike fibres and yet slug slime also contains threadlike fibres. Is there a significant difference between these two slime fibres?  —Preceding unsigned comment added by ElJayDee (talk • contribs) 19:05, 24 March 2008 (UTC)

thread_title:  Heart System 

message: Apparently hagfish is popularly eaten in Korea. This may have to do with the fact that Koreans consider hagfish as a type of "eel" but it's pretty crazy. Found some vids on youtube. Anyone have any ideas on how we can incorporate this into the article?

thread_title:  Assistance in recovering recent edits 

message: The article currently claims hagfish have two brains.  I'm by no means a biology expert, but I'm unaware of any animals with two brains, though some have multiple ganglion.  A brief google search turned up no other mentions of hagfish possessing this attribute, while the German version of the article seems to discuss a singular brain.  I put a citation needed tag next to the sentence in question, as I'm not certain if brain is just a mistranslation of ganglion, vandalism, or what. 129.10.116.80 (talk) 18:18, 26 March 2009 (UTC)

thread_title:  Two Brains? 

message: I am currently taking a comparative vertebrate anatomy course, and we are referring to the Hagfish as Myxinoidea, a class, with superclass Agnatha.  Anyone know what the current "actual" classification is?  In any case, I feel Myxinoidea should be mentioned somewhere, even if it isn't the current "correct" name, as people are still being taught this, and older sources do use it.
Dewert (talk) 22:02, 25 October 2009 (UTC)
replies: text: The classification is disputed, because of an uncertainty whether the lampreys are more closely related to hagfish (which would mean the hagfish are vertebrates that lost their vertebrae) or to other vertebrates. If the latter, than Agnatha should probably not be used at all, or as a grade for jawless "fishes."--Syd Henderson (talk) 23:00, 25 October 2009 (UTC)
thread_title:  Myxinoidea? 

message: I wanted to add this, but it seems to conflict with what is already there. Thoughts?
The mouth of the hagfish has two pairs of horny, comb-shaped teeth on a cartilaginous plate that protracts and retracts. These teeth are used to grasp food and draw it toward the pharynx.

thread_title:  Image of hagfish feeding 

message: This article is deeply confused concerning the principles of systematics and the current state of understanding of vertebrate phylogeny. As well, it contains a number of odd assertions about hagfish (e.g., the lack of an operculum causes them to rely on cutaneous respiration). Someone with actual knowledge of the relevant literature needs to redo much of the articlChore.MayerG (talk) 06:41, 22 November 2011 (UTC)

You may add  after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead.

message: The phylogenetic tree is a bit confusing and could use more information. The symbol next to Myxinikela siroka, for example, is not explained in the description. It could be an improvement if a less focused tree was used to better show the Hagfish's place in the Chordata phylum and in the evolution of vertebrates. JDinauer (talk) 01:04, 27 February 2021 (UTC)
replies: text: † indicates extinct, I have updated it. I think a problem is that the deep phylogeny of the early vertebrates is not that well understood (as far as I'm aware); although there is a reasonably detailed phylogenetic tree on the article Conodont.  It's only when you get to the Gnathostomata that things become clearer. See also the phylogenetic tree on Chordate. --Jules (Mrjulesd) 01:30, 27 February 2021 (UTC)
