Autohaemorrhaging
I was immediately intrigued by this topic when I came across a video of a horned lizard displaying this behaviour. I chose to evaluate this article so that I can determine if it is a good fit for my article contribution, later in the course.

Lead
The Lead concisely describes the article's contents. However, there is not much content to be discussed.

Content
The lack of content in this article seems to be the biggest issue. The article consists of a simple definition of autohaemorrhaging, and a list of animals that display this behaviour. The article simply states that animals "eject blood from their bodies". It doesn't state that some species can eject blood particular sources: from their eyes, mouths, ears, or nostrils. The content is not up-to-date; the latest source is from 2016. The content comes from only 3 sources. There is more recent literature on this topic, but the Wikipedia article does not include it.

Tone and Balance
The tone of the article is neutral, and it does not attempt to persuade readers.

Sources and References
There are only 3 sources for this article, which is not a sufficient representation of the literature on autohaemorrhaging. There are at least 11 facts that are not cited, specifically within the list of species which display this behaviour. The sources are not current; they are from 1987-2016. Recent literature from 2016-present exists, and is not incorporated in this article. The link to the main source does not work. This source is a journal excerpt (2009) that is supposed to list the animals which display this behaviour.

Organization
The article is well-written. It flows well, and does not seem to contain grammar or punctuation errors. The article does not use sub-headings, rather it consists of a list of species which display this behaviour. An expansion of this article may be beneficial. Sections could be devoted to classes of animals which display autohaemorrhaging, and could then differentiate between how this behaviour variates across species.

Images and Media
There are no images in the article. Images would be useful in helping readers understand how this behaviour works. For example, autohaemorrhaging can occur in various ways, but the article simply states that animals "eject blood from their bodies". Photos would easily show the reader that animals can eject blood from either their eyes, mouths, ears, or nostrils. Or, even from multiple sources at one time. Who wouldn't want to see photographic proof of this?

Checking the talk page
There is only one message left on the talk page, from 2013. This comment criticized the inclusion of a detailed description of beetle blood, as the article does not state why the contents of a beetle's blood is significant in this defense mechanism. The article is linked to 2 WikiProjects: Physiology and Animals. It is rated as stub-class within each WikiProject.

Overall impressions
The article is underdeveloped. It lacks meaningful content, relevant sources, and recent sources. The broken link to one of the major sources should be replaced. The article's organization could be improved by including sub-headings, under which the relevant information could fall. Recent literature should then be incorporated into the article. Images would also be beneficial, as this addition may enhance readers' comprehension of autohaemorrhaging.

Autohaemorrhaging has been observed to occur at two different intensities. Blood may be squirted toward a predator as a chemical defence mechanism, if the animal's blood contains toxic compounds. In the second form, blood is not squirted any distance, and it simply runs out of the animal's body. The second form is used by animals that do not appear to contain toxic compounds in their blood, and seems to serve a deterrent effect.

Some organisms have shown an ability to tailor their autohaemorrhaging response. Armoured crickets will projectile autohaemorrhage over longer distances when attacked from the side, compared to being attacked from an overhead predator.

(Maladaptive Aspects)

Autohaemorrhaging may result in dehydration. The ejection of blood puts organisms at risk of cannibalism from conspecifics.
