Hagfish are long and vermiform, and can exude copious quantities of a milky and fibrous slime or mucus from some 100 glands or invaginations running along their flanks.[1] The species Myxine glutinosa was named for this slime. When captured and held, e.g., by the tail, they secrete the microfibrous mucus, which expands into up to 20 litres (5+1⁄4 US gallons) of sticky, gelatinous material when combined with water;[2] one litre of slime has about 40 milligrams of mucus and proteins.[3] If they remain captured, they can tie themselves in an overhand knot, which works its way from the head to the tail of the animal, scraping off the slime as it goes and freeing them from their captor. Rheological investigations showed that hagfish slime viscosity increases in elongational flow which favors gill clogging of suction feeding fish, while its viscosity decreases in shear which facilitates scraping off the slime by the travelling-knot.[4]

This slime that hagfish excrete has very thin fibers that make it more durable and sticky than the slime excreted by other animals.[5] The fibers are made of proteins and also make the slime flexible. If they are caught by a predator, they can quickly release a large amount of slime to escape.[6] If they remain captured, they can tie themselves in an overhand knot, and work their way from the head to the tail of the animal, scraping off the slime and freeing themselves from their captor.

The origins of the vertebrate nervous system are of considerable interest to evolutionary biologists, and cyclostomes (hagfish and lampreys) are an important group for answering this question. The complexity of the hagfish brain has been an issue of debate since the late 19th century, with some morphologists believing that they do not possess a cerebellum, while others believe that it is continuous with the midbrain.[7] It is now believed that the hagfish neuroanatomy is similar to that of lampreys.[8] A common feature of both cyclostomes is the absence of myelin in neurons.[9]

: CS1 maint: unflagged free DOI (link)I will be transferring all relevant parts of my brainstorming to the group sandbox page linked above. I am using this sections to organize my thoughts first.
Adding an image of a hagfish excreting slime to defend against a predator could be helpful and interesting. Using Creative Commons, I was able to find a possible image from Wikimedia Commons that could be used. Here is the link to Wikimedia Commons where the image can be found: https://commons.wikimedia.org/wiki/File:Hagfish_Slime_Predator_Deterrence.jpg.
Link to article: Hagfish
I am planning on focusing on hagfish anatomy. There are some sections in the article regarding hagfish anatomy that could use more information in general.
An example of edits that could be made are adding some more sentences, such as:

: CS1 maint: unflagged free DOI (link)Blog posts and press releases are not reliable because they are not objective. They are usually trying to advertise something or push there own opinions. A company's website can be biased. Companies always want to make themselves look good. If you want information about a company, it is better to look at outside sources that will be more objective. A copyright violation is when you use information from a source when the author did not give permission for it to be used openly. Plagiarism is when you use other people's ideas and do not give them credit. Good way to avoid close paraphrasing and plagiarism is to take notes in your own words. Look at multiple sources to make sure you understand the topic. Always cite your sources and have a Reference section.
(My group was not able to discuss the questions for this week, so I only have my own thoughts written.)
I will be adding to the article by adding 1-2 sentences and citing the statement to a reliable source, as I learned in the online training.
The article I looked at was titled, "Hagfish." Here is the link: Hagfish. Looking at the article, I felt that more information could had been added to explain the phylogenetic tree. I looked at the source from which the author got the phylogenetic tree to learn more about it. This source is #55 in the article. The following is a few sentences that could be added to the article to explain the phylogenetic tree:
The phylogenetic tree depicts the evolutionary history of the cyclostomes. All indicated dates shown are rough estimates. It shows that lampreys and hagfish, both members of the Cyclostomata, separated sometime between 430 and 480 Mya.[1]

A content gap is where there is not enough information. If you read an article and come to a place that does not make sense or makes you confused, there could be a content gap.
A content gap could appear due to poor writing or not enough reliable resources. This can be fixed by obtaining more reliable resources and gaining a better understanding of the topic.
It does not matter who writes in Wikipedia. The important thing is that the person uses many reliable resources and gains a good understanding of the topic before writing.
To be unbiases, you have to use resources that are not trying to sell something or persuade readers in one direction or another. Also, it is important not to make any personal conclusion. This is how I think of being unbiased. It is important to just give the facts, not personal opinions.
For the assigned article: For the article I am evaluating, I think more could said about the phylogeny. I feel like more could be said to explain the figure. For example, what is the meaning of the cross next to Myxinikela siroka on the tree?
(A summary of my thoughts can be found at this link: User:JDinauer/sandbox.)
The article I am evaluating title, "Hagfish." This is the link: Hagfish. The topic of my article is about hagfish in general. As such, everything in the article is related to the topic. There is no distracting content that has nothing to do with the topic of the article. The article seems to be neutral. There was nothing written that suggested that the author added any personal opinions. While there are some areas in this article that could use a little more information, it does not seem like the author is trying to promote one viewpoint over another. The author uses all sources relatively equally. The author does not use one source significantly more than the others. Furthermore, there are many citations, indicating that the author did a lot of research and based the article on facts from that research. Based on the citations I have checked, they seem to be formatted. The links to the original sources seem to work. The original sources support what is written in the article. The references are reliable, most of them being from academic journals, and they do not seem to be biased. There seems to be some places in the article that could use a citation. To check for plagiarism, I put a phrase in the Google search bar to see if anything close to it came up. Some of the sources used are old. I feel like there are sections of the article that could have been made more clear and had more information added, such as the section regarding hagfish eyes or the phylogenic tree. The author gives credit to the original articles. In the talk page of the article, there is a discussion regarding whether the hagfish is a vertebrate or not. There were suggestions regarding missing information that could be added in specific sections. This article is C-Class, and it is a part of WikiProject Fishes, WikiProject Food and drink, and WikiProject Fisheries and Fishing. This article has more information on hagfish than we talked about in class, since we only talked a little bit about hagfish while going over vertebrates.
