I updated my final edits to the Snake page under "Internal organs", the Rattlesnake page under "Skin and circulation", and the Heart page under the "Double circulatory systems". In addition to the information, I added and labeled 2 pictures of the three-chambered heart in the Snake page under "Internal organs".

Additions to the Snake page: Snake's and other reptiles have a three-chambered heart that controls the circulatory system via the left and right atrium, and one ventricle. ^[1]

This sentence can be shown at the very beginning sentence under the "Internal organs" section. The reference clearly lined up in numerical order, and I did not find any problems adding the sentence.

• After looking on Creative Commons, there was no labeled diagrams of a snake heart available
• I will be using my dissected photo to add to the directed pages listed below
• Labeled in this photo are the main components of the heart and circulatory system

Snake three-chambered heart: **A dissected and fully labeled picture of a rattlesnakes' three-chambered heart will be added to the Rattlesnake page after dissection**

Additions to the Heart page: The form and function of these hearts are different than mammalian hearts due to the fact that snakes have an elongated body, and thus are affected by different environmental factors. In particular, the snake's heart relative to the position in their body has been influenced greatly by gravity. Therefore, snakes that are larger in size tend to have a higher blood pressure due to gravitational change. This results in the heart being located in different regions of the body that is relative to the snake's body length. ^[2]

Additions to the Snake page: Snake's and other reptiles have a three-chambered heart that controls the circulatory system via the left and right atrium, and one ventricle. ^[3] Internally, the ventricle is divided into three interconnected cavities which include the cavum arteriosum, the cavum pulmonale, and the cavum venosum.^[4] These components provide the functions of the systemic circulation, which allow the heart to provide oxygen and other nutrients to muscles and tissues of the body.

"To start prepping for those dissections you guys could start listing out the parts of the heart and vertebrae you are planning on labeling." ---Kxr 11

• I plan on dissecting the whole heart and observing the 3 chambers (atria and ventricle). Once I am able to get the dissect the whole heart, I will examine other functional components like major arteries or vessels if they are intact. If I am unable to see any functional components, then I will just label what I can and add it to the Heart and Rattlesnake pages.

"Also, there are a couple of spelling and grammar edits that I would like to make to the Three-chambered Heart section. I will copy and paste a edited version here with the edited parts italicized:" ---GoldenRetriever21

• I have added these edits to my original draft.
• This was very helpful in editing my draft

"However, You have the same sources listed multiple times in your works cited. You can actually just cite it once, and then re-use your original citation. This will make your bibliography shorter and less repetitive/jumbled. I would also suggest adding a header for your bibliography section so that it looks more organized and is separated from the rest of your draft." ---AICOI

• I realized this problem and didn't know how to fix it. This was very helpful in reusing citations since they were the same citations that I used in my draft from my previous plan. I have made this correction in my draft so that the citations are used only once.

• More than one atrium: atria
• I think you should be more specific about how the components allow the heart provides oxygen and other nutrients to the body. You could talk about the flow of blood through the heart and around the body. This would also go hand in hand well with a labeled cross section of the snake heart. I think this would better clarify your section because right now its sounds a bit like a list of chambers, rather than a description of the form and function of the snake heart. ---AICOI
• I realize that my grammar needed some major editing. I fixed these edits in my original draft.
• I wanted to talk about the flow of blood through the heart and around the body (systemic and circulatory systems), but this information is already present on the Heart and Reptile pages, but it is not present in the Rattlesnake and the Snake pages. I will try to add some information to all of these pages or adding the information to the Rattlesnake page and linking it to the Heart page.

"I also urge you to consider making your contributions to this page (heart) and then linking to the snake page. That might make more sense than directly to the snake page." ---Dr. Schutz

• There is currently no pictures of a snake heart on the Heart page, so I will consider adding this to here and then linking it to the Snake page. This would definitely make more sense considering there is already information about the flow of blood in reptiles. I will add little information to each of these pages while also adding the labeled dissected heart of the rattlesnake. My future work will include: dissecting the whole heart, observing any functional components, labeling the heart, and adding information to the desired pages.

I have assigned myself the sandboxes that I want to review. Both of my pieces can be seen under their talk pages. I included a full in depth peer review on all of the group's contributions to the page.

After looking at several Wikipedia pages regarding the snake anatomy, I want to add a picture of my own dissected snake heart and more information about it on the Snake page. In addition, I could also add a picture of the snake heart to the Reptile page since it only has a picture of an iguana's heart. In particular, the Snake page is missing valuable information and a picture about the snake's three-chambered heart. Some things that I would like to add is:

• My own dissected picture of a rattlesnake's three-chambered heart, which is fully labeled and free of any copyright issues. I have searched online for any pics, and there were no pictures of any snake heart's.
• The snake's heart is divided into the atrium (heart) via two atria's and one ventricle (heart) that is divided into three different chambers, which include the systemic and left-sided cavum arteriosum, the pulmonary and right‐sided cavum pulmonale, and the medial cavum venosum. These components allow the heart to provide oxygen and other nutrients throughout the body. ^[6]
• The form and function of these heart's are different than mammalian hearts due to the fact that snakes have an elongated body, thus are affected by different environmental factors. In particular, the snake's heart relative to the position in their body has been influenced greatly by gravity. Therefore, snake's that are larger in size tend to have a higher blood pressure due to gravitational change. This results in the heart being located in different ranges relative to the size of the snake's body length. ^[2]
• Posted to the Talk:Snake regarding the addition of a dissected heart picture that is fully labeled.
• Adding other relevant information and gain feedback about it as time goes on

1. Rattlesnake: This is my top choice because I have always been fascinated about snakes and their ability to eject venom through their fangs, and I would like to apply my knowledge to rattlesnakes since I did a report on the evolution of venom in snakes. One topic that I would want to edit on this page is the Jacobson's organs because little is mentioned about what these structures do and the importance they have in detecting smell.

2. Mudpuppy: This is my second choice because I would like to get to know more about the anatomy and physiology of their red external gills. One topic that I would want to edit/ add to this page is the respiratory system, specifically looking at the gas exchange using the external gills.

3. Iguana: This is my third choice because I had the opportunity to capture one in the Bahamas and I have never gotten to dissect one before. One topic that I would want to edit on this page is the parietal eye because it barely gives a description of the physiology other than it is a "light sensing organ."

• I added 1-2 sentences to the "Skeleton" section of Shark anatomy and then cited it with a reliable source shown below. This change is published to the page.

In particular, the endoskeletons are made of unmineralized hyaline cartilage which is more flexible and less dense than bone, thus making them expel less energy at high speeds. Each piece of skeleton is formed by an outer connective tissue called the perichondrium and then covered underneath by a layer of hexagonal, mineralized blocks called tesserae.^[7]

• Although the page contains important facts about shark anatomy, it is missing relevant information
• Information that should be included are: teeth, eyes or eyesight, sense of smell, ampullae of Lorenzi, etc.
• Under the Skeleton section, all it says is "The skeleton of a shark is mainly made of cartilage". This is true, but more information on the skeleton should be included like more information on the cartilage and why it is different than cartilage on other organisms.
• Information from other sections could be elaborated more since this page is all about the anatomy of the shark
• Under the Fins section, more information about how each fin plays a role in locomotion could be relevant. In addition, it can elaborate about the chemical properties of each fin other than it is made out of cartilage.
• The Tail subsection does a good job explaining how it plays a role in locomotion and how different sharks use this feature.
• There are some claims on this page that are not cited by any sources (Skeleton and Fins sections). This could be evidence of plagiarism.
• The claims presented in this article are "neutral" and there are no claims that appear heavily biased
• Looking at the citations, 7 of the 8 citations seem to be credible (books, shark research center, or scientific articles relating to the topic). They are all cited in correct format. In addition, all of the links directed me to the correct page which showed good credibility. These sources also contained important information and were properly cited next to each claim. On the other hand, reference number eight in the article was not relevant to the article because it was linked to an article on howstuffworks.com which is not credible. Overall, this article page contained important citations that supported each claim, but there should be more cited for the other sections.
• There is nothing relevant on the talk page, and the only thing that was there was an image that was deleted.
• Looking under the View History tab, the last piece of information that was added was on September 24, 2018.
• This article has been apart of other WikiProjects in the past including about sharks, fishes, and animal anatomy. As a result, this article was rated as a "Start-Class" on the quality scale and "Mid to High-importance" on the importance scale. The data presented shows that this article is a good beginners article, but it is missing very important information about the rest of the anatomy of sharks.
