Abstract
In an audit of our predatory SCPs, it has come to my attention that many of our containment methods are not as effective as they can be, and leave a risk of unnecessary waste of human life and resources. As of late, the Foundation has spent upwards of 200,000 USD on disinformation over multiple civilian deaths and lost approximately 6 personnel a year in preventable accidents related to these outdated procedures.
This report compiles information regarding 4975's predation methods by analyzing its anatomical adaptations and similarities to common, non-anomalous predators. Secondly, it recommends new containment procedures and provides a rationale based on this analysis.
The anatomy of 4975 suggests that it is a persistence hunter, similar to early hominids, but it contains differences that lead to the suggestion that it hunts for much longer periods of time and scavenges for food when the opportunity arises.
Using this information, it has been determined that SCP-4975 can be contained in a more efficient manner by providing cadavers to feed on and modifying its containment to prevent its reality-bending hunting methods.
New procedures in the event of a containment breach have also been proposed, to reduce the likelihood of casualties due to previously faulty safety measures.
It is hoped that this report leads to a change in policy, and inform personnel working with SCP-4975 of methods to protect themselves during their work.
Methods
Information regarding the anatomy of SCP-4975 was obtained by tranquilizing the entity and examining the structure of the body as well as taking X-rays of the spine and legs.
Obtaining the information regarding updated containment procedures were obtained through a series of tests with 4975. In an effort to find a suitable feeding material, carcasses of pig, sheep, cattle and human cadavers were provided. Following the cadaver test, live instances of pig, sheep, and cattle were provided over time. Each test was repeated three times, with results recorded and compared to previously collected data.
Afterward, to find a method of halting the entity's 'projecting' abilities, I modeled the results of using SCP-148 sheets, placed into the walls, to stop the telekinetic attacks that 4975 uses. Afterward, I performed real-world testing and found that it succeeded in preventing instances from manifesting. Further changes to the Containment procedures were created using earlier anatomical and behavioral analysis.
Analysis of Hunting
Hunting Style
SCP-4975 demonstrates similarities to early hominids and modern-day persistence hunters in its hunting style. Its hunting methods can be analyzed in three parts, SCP-4975's anatomy, hunting techniques, and favored prey.
The entity's anatomy is structurally similar to early hominids, most obviously through manners of thermoregulation and skeletal structure. Its bipedal movements are the most obvious examples of the skeletal structure, as its experienced changes throughout its body to support upright movement.
The feet appear to be a transitional stage of evolution, retaining the structure expected in avian species, but they have smaller phalanges. This increases energy efficiency during distance walking, as evidenced through evolution in humans. The knees and hip bones have an increased surface area and are moved directly underneath the body to support body weight in a more direct manner.
In addition, 4975 regulates its temperature internally, warming itself through expending energy or movement. However, it decreases temperature through perspiration, allowing cooling to take place during hunting activities rather than forcing the organism to slow or halt in an attempt to cool itself. The lack of feathers and fur assists in this thermoregulation as it allows the sweat to evaporate quickly, while preventing excess heat from becoming trapped.
Seemingly contradictory to the bipedal structure, 4975's muscular and spinal structure lacks the support necessary to prevent long term wear and damage. The spine is elongated to support a thin, long neck but lacks the connective tissue to keep the body and head from moving during vigorous movement.
Such weaknesses are mirrored in SCP-4975's hunting style, as it prefers slower hunts over an extended period of time. This slower pace allows it to take full advantage of the energy efficient structures found throughout its legs while avoiding the damage caused by confrontation or exertion.
SCP-4975's primary hunting technique is to exploit the exhaustion experienced by its prey. Through the cracking noise, which I currently believe to be an intimidation mechanism, they produce nonanomalous anxiety, which often progresses to insomnia.
Over the course of several months, decreases in rest results in paranoia, social isolation and physical weakness. 4975 uses these symptoms to its advantage as it is able to easily overcome an isolated and weakened organism, with minimum risk to itself. In cases of extreme stress, or extended periods without food, 4975 has been recorded instead to attack prey earlier.
The same techniques are witnessed in its anomalous hunting method witnessed in earlier 'containment breaches', where the entity was able to attack and feed upon a civilian despite never having left containment. I suspect that these attacks are performed via telekinetic means, however, I cannot make the observations necessary without inducing another attack. The characteristics, however, are all in line with a telekinetic attack. In both, materials can be transported, physical force is used at a distance, and they required the projector to focus on the attack for it to be successful.
Finally, the structure of the beak and head is similar to that of the vulture, with a sharpened beak for improved tearing of flesh and a lack of feathers to ensure cleanliness when consuming prey. These changes suggest that 4975 may act as a scavenger when the opportunity arises.
Favored Prey
Unsurprisingly, 4975 focuses efforts upon already weakened or isolated prey. This behavior is not unusual in predatory creatures and is performed to reduce the struggle experienced during hunting. Prey has been selected largely based on age, a significant number of suspected victims of 4975 throughout history are above the age of 50, and a similarly large proportion of victims were ill or wounded.
Younger individuals 4975 has targeted are skewed towards juveniles, especially those left unattended. However, in cases preceded by a drought of hunting, there has been a single case of a group being hunted as well as several instances of healthy individuals being targeted.
After testing, it has been found that 4975 will readily consume cadavers in place of live prey, however, this appears to be limited to humans, as it has avoided common cadaver substitutes including pork, sheep or cattle. Further testing was performed with live prey, and it has been found that, despite the aversion to carcasses provided, 4975 will attack and consume live sheep and pig. I suspect that cattle are ignored due to their larger size.
Such methods are common throughout other predator species, most notably pack predators such as wolves and lions. This shared characteristic is likely unrelated to the pack style hunting seen in such predators, however, I suggest continued monitoring to ensure there are no other 4975 instances. Similar patterns can be seen as they target weaker members of herd animals, with a preference for isolated individuals due to their relative ease of capture. The aversion to larger, or more dangerous prey, is also present in modern hunters as they avoid mothers or leaders of the heard.
Suggested Containment Procedures
Updated Language
SCP-4975 is to be contained in a standard steel containment cell with telekill sheets placed in the room, and rotated weekly. Human contact with SCP-4975 is prohibited. A single sheep is to be provided monthly at a randomly selected date and time.
In case of a containment breach, any Foundation personnel persistently hearing a rhythmic cracking noise are to isolate themselves from other people and patiently wait until SCP-4975 is put back in its containment chamber, or the cracking stops. seek armed personnel to travel with, and avoid isolation.
Rationale
Due to the weaknesses examined in 4975's anatomy, as well as the preferred prey, I believe the most significant change that should be created is the reversal of policy during containment breaches. SCP-4975 is more likely to take aggressive action against individuals if they are unaccompanied, I suspect that between 10 and 30 individuals have been terminated by the entity since its capture due to the faulty procedures.
Secondly, 4975 has demonstrated an ability, and willingness to hunt innocent individuals through the secondary, anomalous hunting methods. As such, I suggest providing designated prey for SCP-4975 that fulfills its generally favored traits, as well as being within close proximity to limit its hunting range to desirable targets. This prey is offered at a random interval to protect the lives of personnel, as 4975 will be unable to anticipate feeding times or make any attempts to breach containment.
Finally, testing with SCP-148 has proved effective in halting 4975's long-range telekinetic feeding. Models project that critical levels of energy are reached after a month of use, providing ample time to exchange the 148 mass in the event that an event prevents regularly scheduled exchanges. I do not believe there is a serious risk of overcharge due to the relatively isolated forces 4975 exerts, resulting in a very slow charge.
By implementing these changes, we can expect a significant reduction in casualties and costs caused by SCP-4975. Unexpected civilian deaths will be entirely prevented, as will the cost of disinformation regarding the deaths, and foundation employees will become more difficult targets, dissuading attacks and reducing the replacement rate required for individuals assigned to work with 4975.

Abstract
SCP-844, henceforth referred to as the entity, is an ambush predator that relies on auditory stimuli to attract prey. The entity has been known to consume a variety of organisms, including humans, but has consumed only bovines following Foundation containment. The entity is composed of skeletal remains of prey, miscellaneous sediments and a previously unclassified 'fungal' organism.
Current Special Containment Procedures are dangerous and result in unnecessary loss of life and limb during the monthly size reduction. With the goal of reducing the number of preventable causalities, tests have been completed to investigate the identity, importance and behavior of the fungal organism that partially comprises the entity.
Sample colonies of the unknown organism were cultured; then morphological data and phylogenetic data was collected to find similarities between the entity and known species. Behavioral testing was performed using sterilized samples of the entity that lacked the unknown organism and compared to unsterilized samples to find the roles filled by the organism and the processes employed when capturing prey.
Initial testing resulted in significant variations from all known species; however, comparisons with 'slime molds', single-celled colonial Protists, revealed similarities with the Labyrinthulea classification. Morphological testing confirmed this classification, examination reveals cells travelling along a membrane network that is a common feature of the Labyrinthulea classification.
Due to the newly found data, it is my opinion that the information contained in the SCP-844 datasheet should be updated to reflect the updated information. Additionally, further experimentation should be conducted to discover an anti-protist agent(s) to be used in the event of a containment breach and to replace the current practice of manual size reduction.

Introduction
Containment procedures for Safe-Class entities are revised and updated less than 3 times a decade, creating unsafe environments for Foundation personnel and D-Class alike. These unsafe conditions have led to aging infrastructure among Safe-Level containment zones, and an average of 2 casualties per Safe-Class entity.
SCP-844 specifically has taken the lives of 5 D-Class, and injured 6, over the last decade. These needless costs to the Foundation can be stopped through thorough examination of dangerous entities and their Special Containment Procedures. Most casualties have occurred during the 'monthly shearing' procedure, detailed as follows (Hyne 2011):
Each month, SCP-844 is to be reduced in size by two (2) D-class personnel using shears.
Any personnel entering SCP-844's containment chamber must wear a protective suit in order to prevent injury or death.
If research is conducted to increase the available information related to SCP-844, then safer containment options can be chosen with updated, accurate information.
Genetic tests were performed due to their standardized nature and frequent use in other phylogeny studies. Morphological tests provided a confirmation of the genetic results and compared the expressed anatomy of the organism with known organisms.
Materials and Methods
1. Materials and Organisms Used
- SCP-844 (Entity information found in the SCP-844 Datasheet)
- 297 Genetic Sequences of Example Slime Mold Species (List of Species located in SCP-844 Study 23 Datasheet)
- FSSA (Foundation Standard Sequencing Apparatus)
- Treegen 4.3
- Compound Light Microscopes (40x-1000x)
- Microscope Slides
2. Phylogenetic Testing
297 total sets of genetic key sequences were obtained from sample organisms of slime molds; accounting for most species of both the non-amoebozoan slime molds, Dictyosteliida and Protosteloid groups, and a sufficient number of Myxogastria to determine common ancestry. Genetic samples were obtained through tissues preserved by contacts with researchers specializing in slime molds located in Hokkaido University and The University of the West of England.
Using FSSA the genetic information of the entity was recovered from samples obtained during monthly trimmings. The entity's cells were separated from those of it's prey's remains by beginning cultures of the samples, and using standard streaking procedure to isolate the proper culture.
Finally, Bootstrapping procedures were performed using commercial software (TreeGen 4.3) and repeated 1000 times with each sample to form a set of phylogentic trees. Any trees that failed to occur with more than 90% repetition were discarded, and an initial figure was generated based on this information. This smaller pool was then subjected to a repeat test, the most common results (>98% repetition) were accepted as the final datasets, and a graphic was regenerated using this information.
3. Morphological Testing
In order to ensure genetic testing was consistent with the physical structures expressed in the entity, morphological testing was conducted to further support the finalized phylogentic trees. The focus of these experiments were to locate a tube network, fruiting body, or pseudopodia structures; any of which would be sufficient to establish which grouping the entity is likely to belong to.
100 live samples of the entity were isolated and examined using compound light microscopes at 1000x magnification, notable structures were then photographed and recorded for analysis.
Results
The results output from the TreeGen program show that the entity has a genetic makesup that is most similar to the Labyrinthulea group of slime molds, with a 98.6% recurrence rate. Results indicating the relations between non-anomalous slime mold species are concurrent with known studies on the topic, and given its irrelevance to the entity, the data has been excluded from this article.
Photos of a SCP-844 cell (Left) and a Labyrinthulea cell (Right)
Morphological analysis found examples of plasmoidal tube networks extending between colonies of the entity, with similar structure to those found in Labyrinthulea. However, these networks varied in that they were procedure in greater numbers and appear to act as methods of locomotion in of themselves, rather than simply acting as pathways for the colonial cells to travel along.
Discussion
Given the newly found identity of the entity; I formally request that the information contained in the SCP-844 Datasheet and Containment Procedures are reconstructed to correctly represent the nature of the anomaly we are containing to limit misinformation and dangers posed by misled protocol.
1. Suggested Containment Procedures
(Updated language has been bolded, removed text has been crossed out)
SCP-844 is currently contained at Site ██. SCP-844 is to be contained in a well-lit chamber measuring 6m x 6m and provided with one (1) bovine each month specialized nutritional agar in accordance with Nutrition Chart 844-2. Each month, SCP-844 is to be reduced in size by two (2) D-class personnel using shears using regular treatments of the anti-protist agent pentamidine.
Any personnel entering SCP-844's containment chamber must wear a protective suit in order to prevent injury or death.
2. Rationale
Results indicate a possible vulnerability to anti-protist agents commonly used on non-anomalous varieties of protist, given the strong connection between SCP-844 and known slime molds. Pentamidine is the most likely choice of anti-protist agent, as it inhibits the production of lipids (Lemke 2013). Once these lipids were slowed or stopped in production, the plasma membranes making up the tube systems could not be formed, limiting the size of the entity.
These restrictions would immobilize the entity beyond cellular locomotion, preventing it from using the plasmid tubes as a muscular system. The reduction in size weakens the entity so that future attacks against Foundation personnel are nonlethal, if they are successful. This would allow further research and safe containment of SCP-844, without needing to neutralizing the entity or risking lives of additional personnel.
Finally, the exchange of bovine food sources in exchange for a specialized nutritional agar prevents SCP-844 from utilizing its prey's skeletal system as weaponry, providing an additional containment system by disarming the entity on top of its weakened state.
3. Further Discussion
In order to achieve the Special Containment Procedures I currently recommend, further research should be conducted over the following topics: the efficacy of anti-protist agents; the nutritional requirements of the entity; and the importance of prey material to the entity.
Despite the close relationship between the entity and several species in which Pentamidine have proven to be effective in; it may prove to be excessively effective or ineffective, resulting in the neutralization or failed containment of SCP-844 if a relationship is not established. Other agents should additionally be explored to ensure alternative options if Pentamidine becomes ineffective over time.
In order to establish a proper mix of nutrients to replace the current bovine food stocks, the nutrients that the entity requires must first be established. The proper nutritional mixture is important to ensure that the entity is capable of surviving on the provided substrate, and that they aren't provided with an excess of food that may drive them to grow excessively.
Prey material has already been established as a valuable tool in SCP-844's hunting strategies. However, the structural benefits the entity gains apart from these strategies has not been explored. This line of research could lead to discoveries in beneficial construction strategies for the Foundation to use. In the matter at hand, we can use this information to find if the transition from bovine to agar food sources is practical for the entity's survival.
Conclusion
In an attempt to identify the unknown fungal entity comprising SCP-844, this experiment was conducted to establish genetic and morphological links to the protist groups colloquially known as 'slime molds'. Data found shows that the genetics of SCP-844 are most similar to the Labyrinthulea classification, with morphological studies confirming this with the presence of locomotive tubes surrounding individual cells. Using this data, I urge that the aforementioned changes are made, and further research conducted to preserve the lives of D-Class and Foundation personnel alike, while simultaneously expanding the knowledge of the Foundation.
