Article Evaluation for Coprophagia
This article contains all portions and subtopics that are relatable to the main topic. It provides information of a wide variety of organisms that exhibit coprophagia including invertebrates, vertebrates, humans and even plants, and gives details on specific species and reasoning as to why some species carry out this eating behaviour. If any of these organisms are under represented in information it would be the humans, as we are only provided with a brief sentence discussing this eating behaviour in mental illness, along with a portion on society and culture were we are provided with coprophagia in association with human activities. As well, the plant information is too under represented and next to no information was given. There are sufficient references used as information in this article and appear to be of a wide range, suggesting that many views and research have been taken into consideration when writing this article. All citations work and appear to be appropriately placed in the article and of a appropriate source. With an exception to the history of this article, which is expected to be of an older date, all other information is fairly recent and suitable. When looking into the Talk page of the article, there is much discussion on the idea of this eating behaviour and mental illness, along with a list of films and TV series that relate to this eating behaviour. This article overall provides a great overview and much detail in some aspects of coprophagia in many different organisms and species, showing that it is not just a select group that carry out this behaviour but it is in fact popular.

Two feces-eating insects are certain species of fly and the dung beetle. In regards to the dung beetle, their diet is mainly in the form of the microorganism-rich liquid component that is present in the dung of mammals, while they take advantage of the fibrous material in the dung for the female to lay her fertilized eggs in.

Week 5 Topic Idea
Paedophagy https://en.wikipedia.org/wiki/Paedophagy

TA: This sounds like a good potential topic, just make sure you can find enough primary literature on the subject to support a significant contribution.

Week 6 Plan
Paragraph topics I plan on adding to the already existing article Paedophagy are: Parental care: discuss mouth brooding, behaviour: discuss how the eggs are captured, history: the drying up of the lake(s) (i.e Lake Tanganyika) and benefits: discuss the advantages of eating eggs

Articles/books I plan on getting information from: "The Cichlid Fishes: Nature's Grand Experiment In Evolution" By George Barlow (Book) "Mitochondrial phylogeny of the endemic mouthbrooding lineages of cichlid fishes from Lake Tanganyika in eastern Africa" C Sturmbauer and A Meyer (Article) "On the evolutionary pathway of parental care in mouth–brooding cichlid fishes" S. Balshine-Earn and David J. D. Earn (Article)

Draft
Paedophagy (literally meaning the "consumption of children") is the feeding behaviour of fish or other animals whose diet is partially, or primarily the eggs or larvae of other animals.

The term paedophagy in its general form is common among the animal kingdom. However, P.H Greenwood, who was the first to describe paedophagia in regards to cichlid fishes, defines paedophagy in the sense of a feeding behaviour evolved among cichlid fishes.

 Location  Paedophagy is found in fishes from the African Lake Victoria which in total has 200-300 species but in regards to paedophages it is know to contains 8 species The African Lake Malawi has in total 500-1000 species but in pardophages only contains several species. Other lakes are Lake Edwards and Lake George which both contain only one species of paedophages From Lake Malawi we see various species of cichlid fish that are paedophages from of the genera Caprichromis, Hemitaeniochromis, and Naevochromis. In Lake Tanganyika species of the genus Haplotaxodon and possibly Greenwoodochromis bellcrossi may also be implicated in this sort of feeding strategy

Mouth brooding Mouth brooding is the most common form of parental care in African cichlids, and it has thought to have evolved from the ancestral mode of care known as substrate-guarding. Other behaviours include those of the species Plecodus straeleni which belongs to the family Cichlidae When this species exhibits paedophagy it has been observed circling and waiting outside the bower, which is the spawning location for many cichlid fishes, until the eggs have been laid before attacking the mouth brooder However, stealing from the mouth brooding phase is not the only tactic that has been noted, there has also been observed the stealing of fry from the guarding phase of parental care

a)Stealing from mouth brooding phase: Behaviours of the predator here involve the three main methods of obtaining eggs from the mouth brooder as previously mentioned.

b)Stealing from guarding phase: This involves juveniles who are being guarded by their parent and a paedophage hunter comes along. The parent will do its best to chase away the predator to protect the offspring, on the other hand, this abrupt movement from the parent distresses the offspring who then all aggregate together until their mother successfully comes back where they continue with guarding behaviour There are some cases where the fry may try to enter the mother’s mouth once she reappeared but these fry would only be rejected as the threat was over. The only exception to the fry re-entering their mother’s mouth is if the mother has been disturbed by the attack and feels it is unsafe, at which point she could carry out a calling movement and all the fry would enter her mouth for a short period of time before being released

Morphology: To obtain the brood without causing serious harm to the mouth brooder paedophages have features such as protrusible and distensible spacious mouths and deeply embedded teeth that are covered by a thickened oral mucosa These large mouths allow the paedophages to engulf the snout of a mouth brooder and discharge the brood, while the teeth adaptation allowed for the paedophage to avoid becoming too heavily attached to the parent which prevents the loss of the brood that the paedophage just obtained

Trade-offs: Achieving the brood from a brooding parent is not always an easy task, it can take great energy and recourses from the paedophage. However, their persistence is rewarded as the eggs are highly nutritious and fairly large when compared to the size of other fish eggs in that they are 3.4mm in diameter on average

Week 11: Peer Review by Macparent
This needs a lot of revision and editing. You are missing the majority of your periods, and many sentences need to be re-worded as there were some run on sentences and improper grammar. As well, a lot of punctuation needs to be fixed up or added in. There are many commas needed. I also question some paraphrasing from your sources, hence why sentences need to be rewritten. Please note that there is more editing of grammar, punctuation, and sentence structure needed than just what I mentioned.

You need to be clearer in your writing and what you are including. Much of what was here I was unsure how this was related to your topic clearly. More explanation on some terms would be helpful too, as well as including wiki hyper links to some words and animals.

As well, your references are not inputted correctly, and you are missing all of the authors names in the references which is important to include. Some do not seem to be from primary literature, but I cannot tell exactly because of how they are written. But all references should be from primary literature for this.

I would recommend going through some of the training's again and then edit the article.

When you use subheadings, use it as a heading, then start the paragraphs on a new line. Not with a colon between. Use them as title headings (like how I have them below).

I separated each section for the more specific edits.

Location
If you mean to say Lake Victoria, write “… fishes from Lake Victoria in Africa…” It just reads better. Same with the other lakes you mention, try not to say African Lakes unless you are using it as a general term. Only mention the amount of species that are paedophagic in each lake, no need to mention the total amount of fish species.

Also fix up some grammer, like “Other lakes are Lake Edwards…” It does not read very smoothly. Could say something like “Other lakes include…”

Do not use the term “we.” Avoid pronouns when writing for articles like this.

Mouth Brooding
First sentence: “…and it has thought to have evolved…”

“Upon hatching, development occurs…” Add a coma.

The last sentence starting with “Typically…” need to add other words, improve the flow of it.

Saying that juvenile fish develop into fry in the fishes mouth is incorrect. In a fish life cycle, fish are fry first, then develop into juveniles as they mature. Juvenile fish are the older than fry, not younger.

Explain mouth brooding more and describe how it relates to paedophagy. I could not relate what is written to the topic at hand at all.

Behaviour
“The first method is…”

Dislodge her brood from what?

“… there has also been observed the stealing of fry…” needs rewording.

Option a isn’t needed as it is what you mentioned in the first paragraph of that section. You also mention this. Instead of saying a and b, just start a new paragraph with no heading for section B.

Run on sentence for the second sentence after the stealing from guarding phase title.

Trade-Offs
This section needs to be re-worded as it sounds a bit one sided. Avoid saying it is not an easy task and how their persistence is rewarded. It is not good writing for this type of article.

Draft After Peer Review
Paedophagy (literally meaning the "consumption of children") in its general form is the feeding behaviour of fish or other animals whose diet is partially, or primarily the eggs or larvae of other animals. However, P.H Greenwood, who was the first to describe pardophagia defines it to be a feeding behaviour evolved among cichlid fishes.

Location
Paedophagy is found in fishes from Lake Victoria in Africa which in total has 200-300 species, but in regards to paedophages it is known to contain 8 species. Lake Malawi in Africa has in total 500-1000 species, but in paedophages contains only several species. Other lakes which contain paegophages include Lake Edwards and Lake George, both in Africa, and each contain only one species of paedophage. From Lake Malawi there are various species of cichlid fish that exhibit paedophagia, they include fishes from of the genera Caprichromis, Hemitaeniochromis, and Naevochromis. In Lake Tanganyika species of the genus Haplotaxodon and Greenwoodochromis bellcrossi may also carry out this sort of feeding strategy.

Mouth brooding
Mouth brooding is the most common form of parental care in African cichlids, and has thought to have evolved from the ancestral mode of care known as substrate-guarding. As mouth brooding is so well known in cichlids, one of the main approaches of paedophages is to steal the brood directly from the mouth of a mother. Upon hatching, development occurs in the mouth until juveniles are well-formed fry, the fry then develop further in the mouth until ready in which they are the released. Typically followed by a phase of parental guarding. Since the young are kept inside the mothers mouth for an extensive amount of their juvenile life it creates a great opportunity for paedophages, as there is a high probability of a female cichlid to possess young in her mouth.

Behaviour
There are three main methods or behaviours that the predators use to obtain the eggs or young. The first method is voluntary jettisoning of a brood, second being snout-engulfing which forces a brooding female to dislodge her brood from her mouth and lastly, is head-ramming against a brooding female which then causes her to spit out a part of her brood. Other behaviours include those of the species Plecodus straeleni, which belongs to the family Cichlidae. When this species exhibits paedophagy, it has been observed circling and waiting outside the bower, which is the spawning location for many cichlid fishes. It waits until the eggs have been laid before attacking the mouth brooder. However, stealing from the mouth brooding phase is not the only tactic that has been noted, stealing of the fry from the guarding phase of parental care has also been observed.

Stealing from mouth brooding phase
Behaviours of the predator here involve voluntarily jettisoning of a brood, snout-engulfing which will force a brooding female to dislodge her brood from her mouth and head-ramming against a brooding female which then causes her to spit out a part of her brood.

Stealing from guarding phase
This involves juveniles who are being guarded by their parent are approached by a paedophage hunter. The parent will do its best to chase away the predator to protect the offspring, on the other hand, this abrupt movement from the parent distresses the offspring. The offspring then all aggregate together until their mother successfully comes back, where she continues with guarding behaviour. There are some cases where the fry may try to enter the mother’s mouth once she reappeared, but these fry would only be rejected as the threat was over. The only exception to the fry re-entering their mother’s mouth is if the mother has been disturbed by the attack and feels it is unsafe, at which point she could carry out a calling movement and all the fry would enter her mouth for a short period of time before being released.

Morphology
To obtain the brood without causing serious harm to the mouth brooder, paedophages have features such as protrusible and distensible spacious mouths and deeply embedded teeth that are covered by a thickened oral mucosa. These large mouths allow the paedophages to engulf the snout of a mouth brooder and discharge the brood, while the teeth adaptation allowed for the paedophage to avoid becoming too heavily attached to the parent which prevents the loss of the brood that the paedophage just obtained.

Trade-offs
Achieving the brood from a brooding parent can take great energy and resourses from the paedophage. However, the eggs they obtain are highly nutritious and fairly large when compared to the size of other fish eggs in that they are on average 3.4mm in diameter.
