Summary of Peer Review:
Taken directly from page:
"In the shark anatomy image, it depicts the beginning half of the shark, including the gills. The shark gills are especially important and were evolved from the chordate pharyngeal gill slits synapomorphy. Gills are essential for sharks to breathe underwater. Like other fishes, sharks extract oxygen from water as it passes over their gills. The water enters through the mouth, passes into the pharynx, and exits through the gill slits (most sharks have five pairs, the frilled sharks, cow sharks, and sixgill sawshark have six or seven pairs). Most sharks also have an accessory respiratory opening called a spiracle behind their eyes. In bottom-dwelling sharks such as angel sharks, the spiracle allows them to take in water to breathe without having to open their mouths citation needed.
There are two mechanisms that sharks can use to move water over their gills: in buccal pumping, the shark actively pulls in water using its buccal muscles, while in ram ventilation, the shark swims forward, forcing water into its mouth and through its gills. As buccal pumping is more energy-intensive than ram ventilation, the former is generally used by sedentary, bottom-dwelling sharks while the latter is used by more active sharks. Most sharks can switch between these mechanisms as the situation requires. A few species, such as the great white shark, have lost the ability to perform buccal pumping and thus will suffocate if they stop moving forward.

Spiracles are a cartilaginous structure located on the top of a sharks head to draw oxygenated water from above in addition to it passing over the gills. [3] [4]

There are two mechanisms that sharks can use to move water over their gills: in buccal pumping, the shark actively pulls in water using its buccal muscles, while in ram ventilation, the shark swims forward, forcing water into its mouth and through its gills. Buccal pumping is more-energy intensive than ram ventilation. Sedentary, bottom dwelling sharks generally use buccal pumping to move water over to their gills compared to more active sharks, who will use ram ventilation and swim to force water to its mouth and gills. Most sharks can switch between these mechanisms as the situation requires depending on the abundance of oxygen in the water. A few species, such as the great white shark, have lost the ability to perform buccal pumping and will suffocate if they stop moving forward due to insufficient oxygen passing over their gills. [5]
Note: on the Shark Anatomy Page there is no "Cardiovascular System" section but a "Circulatory System" section and I will add information about the cardiovascular system here. I'm unsure if I want to tackle this system as well or should focus on the respiratory system more. Any opinions/insights are appreciated!
Taken directly from page:
Sharks possess a single-circuit circulatory system centered around a two-chambered heart. Blood flows from the heart to the gills where it is oxygenated. This oxygen-rich blood is then carried throughout the body and to the tissues before returning to the heart. As the heart beats, deoxygenated blood enters the sinus venosus. The blood then flows through the atrium to the ventricle, before emptying into the conus arteriosus and leaving the heart.
Will add a whole new paragraph here] ****There is also an image of a dissection that I plan to replace***

Sharks possess a single-circuit circulatory system centered around a two-chambered heart containing an auricle and ventricle [6] Blood flows from the heart to the gills where it is oxygenated. This oxygen-rich blood is then carried throughout the body and to the tissues before returning to the heart. As the heart beats, deoxygenated blood enters the sinus venosus. The blood then flows through the atrium to the ventricle, before emptying into the conus arteriosus and leaving the heart.

The circulatory system and respiratory system interacts closely together. it As water rushes over their gills, shark have a body temperature similar to the water. [7]
****This would be a way to start this new paragraph for this section, but I think I'm trying to bite off more than I can chew*****
Group Reflection:
Note this edit is for the Shark Anatomy page under the respiratory system section. I want to add more information and propose a sub-section discussing the ventilation system the Spiny Dogfishes utilize. This is a fairly short section and it has a few images. I can potentially ad more images during dissection illustrating the internal gill structures. Below is the copy-and-pasted excerpt of the "Respiratory System".

Overall, this section is small and there is many opportunities, where I can elaborate on certain information. There was only one citation per paragraph, but once I add more information it will be more in depth.
Group Work sandbox (my own personal one for ideas)
Goal: Initially work on our own separate pages, but once we see overlap, we can link to each other pages. We want to build on our own pages then as a group come together to identify the overlaps.
**Honorable mention: I wanted to look more into the spines on the dorsal fin, but I could not find any Wikipedia pages containing that information.
This is where I will place my ideas on editing this Wikipedia Article and other notes I will have.
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.
In most of the world, hagfish are not often eaten. In Korea, the hagfish is a valued food, where it is generally skinned, coated in spicy sauce, and grilled over charcoal or stir-fried. It is especially popular in the southern port cities of the peninsula, such as Busan. citation needed
