Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: A perimeter of 52 kilometers, marked by a mesh wire fence, has been established to enclose SCP-XXXX. The perimeter includes a safe zone of approximately 200 meters between the fence and the estimated outer boundary of SCP-XXXX. Five access points are placed along the perimeter to allow personnel access. At regular intervals of 50 meters along the perimeter fence are two standard-issue security cameras and motion sensors, to detect both the entry of unauthorised personnel and active instances of SCP-XXXX-2. Weekly inspections are required both inside and outside the perimeter fence to verify its structural integrity and the continued functionality of monitoring equipment.
At each entry point is a personnel station that is to be manned at all times by at least four (x4) Foundation staff. These staff are required to monitor their designated section of the perimeter fence through both physical inspection and camera monitoring. The station and staff are to be equipped with uniforms of local parks and services rangers and provide standard cover story to civilians or members of government services who come across the perimeter fence. Personnel station #03 contains additional sleeping quarters and an armory for MTF-198 "Higgins’ Heroes", which is to be deployed should instances of SCP-XXXX-2 manifest within SCP-XXXX. Staff are to be rotated from SCP-XXXX on regular basis of 6 months, while MTF-198 is to be rotated on a basis of 4 months.
In the event that any civilians or unauthorized personnel penetrate SCP-XXXX's perimeter wall, Foundation staff are to immediately locate and retrieve them before the maximum safety timeframe within SCP-XXXX is exceeded. Should unauthorized personnel stay long enough for an instance of SCP-XXXX-2 to manifest, MTF-198 is to be dispatched to retrieve survivors and remains of deceased, and to terminate the instance of SCP-XXXX-2 if it is still extant. Survivors must be administered Class A amnesiacs and provided with a cover story when handed over to local authorities, and monitoring by Foundation staff will be undertaken for 6 months following the incident they are involved with to ensure they are not at risk from exterior incursions of SCP-XXXX-2.
Description: SCP-XXXX is an area comprised of a freshwater lake and its immediate surroundings, located in ██████████ County, ███ ██████. The lake has been used as a recreational location since the early twentieth century, but has been closed to the general public since Foundation acquisition on 13/06/19██. SCP-XXXX came to the attention of the Foundation after numerous disappearances and deaths in the area were reported.
The environment of SCP-XXXX is comprised of a freshwater lake surrounded by light woodland and acts as the catchment basin for the ████████ River. Several buildings are located on the lake's shoreline, including two large houses, one barn, one boatshed, and five log cabins around a communal camping ground. The houses are constructed in the Queen Anne style of architecture; construction records for these and indicate that they were built between 1895 and 1908, and also state that the cabins were built after the Second World War. The barn and boatshed are not listed within the site until 1957 and 1971, respectively, and it is currently unknown which companies or owners are responsible for their construction prior to these dates. No owners of these buildings and camping grounds are listed in records unearthed by Foundation researchers. Despite the lack of owners and frequent habitation, the interiors of all buildings have been reported to be kept in good condition.
SCP-XXXX's effects consist of two distinct phases. During the first phase, SCP-XXXX-1, no physical anomalous properties are displayed until approximately 6 to 9 hours after entry into the exclusion zone, which has been calculated to begin at 200 meters within the perimeter fence. During the initial hour of entry, subjects experience no anomalous occurrences, but subsequently begin to experience increasing levels of anxiety and paranoia, and heightened fear responses. If the subject leaves SCP-XXXX during this time, these feelings quickly decline, but will rapidly resume should they reenter the zone of SCP-XXXX's influence. The effect is believed to be cumulative and is a primary factor for the regular rotation of staff on-site.
The second phase of SCP-XXXX begins when a humanoid entity, designated SCP-XXXX-2, manifests within SCP-XXXX's area of influence and proceeds to hunt down and kill any subjects who are still present. SCP-XXXX-2 shows extreme hostility upon manifesting and will continue its pursuit of affected subjects unless terminated; it is not restricted to SCP-XXXX’s area of effect and has been observed to pursue subjects up to ██ kilometers away. Despite this, SCP-XXXX-2's actions are presumed to be defensive in nature, as it exhibits a tendency to ignore subjects who have been present for a shorter period of time than its targets. Personnel who attempt to interact with or halt SCP-XXXX-2 following its manifestation are then targeted and pursued as with other affected subjects. Once it has eliminated all affected subjects, SCP-XXXX-2 enters the lake of SCP-XXXX and sinks, presumably drowning in the process.
SCP-XXXX-2's resilience and resistance to injury is well documented, but on four (x4) occasions it has been successfully terminated by members of MTF-189 and its corpse retrieved for study. Each instance of SCP-XXXX-2 has displayed the following physical anomalies:
- Presence of dense bondings within bones and muscle fibers,
- Absence of several major organ groups belonging to the digestive system, reproductive system, and waste system, with the remaining cavities taken up by muscle,
- Absence of chromosomes and genetic information within all cells found in the body,
- Absence of frontal lobe and gray matter within the brain relating to higher intelligence or brain functions.
Despite these anomalies and the recovery of SXP-XXXX-2’s remains, it has been observed to manifest in subsequent appearances with an entirely new body. SCP-XXXX-2 has also displayed elements of strategy and nonlinear thinking when tracking down subjects it is targeting, and appears to have a capacity to understand human speech and body language. The full extent of its mental abilities is unknown at this time.

Item #: SCP-XXXX
Object Class: Keter
Special Containment Procedures: Samples of SCP-XXXX must be kept in a Class-3 biohazard containment area, with appropriate safety protocols to be undertaken to prevent infestation through exposure to both eggs and larval stages that may be extant. Staff conducting analysis and experimentation on samples of SCP-XXXX are required to submit to regular screening and testing to ensure they have not been accidentally exposed. Should any instances of SCP-XXXX be detected, the afflicted staff must be kept in quarantine for a minimum of 14 days and administered with the following medications:
- Praziquantel
- Pyrantel
- Tiabendazole
- Albendazole
Regular screening is to be conducted throughout the duration of quarantine. If the infestation shows signs of having been stopped, an additional 7 days of quarantine under supervision are to be conducted with additional treatment. Unsuccessful treatment of infestation will result in immediate euthanisation and incineration by on-site biohazard staff.
In the event that multiple instances of SCP-XXXX are encountered and discovered to constitute a mass infestation, a quarantine perimeter of 2.5 kilometres must be established around the central zone of infestation. Once the area has been cordoned off Foundation staff, posing as members of the Critical Care Air Transport Team or its local equivalent, enter the affected area to assess the extent of SCP-XXXX infestation and determine the best course of action for decontamination. Any infested livestock or civilians in the affected area must be isolated and terminated.
As of 07/29/20██, common pesticides and poisons used in agricultural practices do not affect newly-recovered specimens of SCP-XXXX. This document will be updated once new pesticides have been approved for use in containment procedures. As of this date, recommended medications in human infestations are still effective in slowing and/or halting the progression of SCP-XXXX's growth, but it is recommended that alternatives be sought in case of immunity in the near-future.
Description: SCP-XXXX is a parasitic organism which manifests itself in the digestive organs of large mammals. It was first encountered in ████████, ███████ on 06/20/19██, when private reports of an unusual parasitic infection in dairy cattle were intercepted by Foundation agents. Subsequent investigation uncovered evidence of parasitic infestation in seven other locations throughout the country. The infested cattle were quarantined and euthanised, with surviving instances of SCP-XXXX preserved for study and experimentation at Site-12.
Most documented incidents involving the parasite have been restricted to cattle and populations of grazing animals found in rural areas. In all recent cases, however, cross-species infestation has occurred and affected localised human populations. In order for infestation to occur, the potential host must have physical contact with either eggs or larvae from a mature specimen of SCP-XXXX. Exposure to bodily fluids of an infested subject and consumption of contaminated foodstuffs are the most common source of initial exposure to SCP-XXXX, though there may be other mechanisms of infestation that are as yet unknown.
The lifecycle of SCP-XXXX resembles that of many parasitoid organisms found in the animal kingdom, the closest being found in the phylum Nematomorpha. When the eggs of SCP-XXXX are ingested by a new host organism, they hatch when exposed to temperatures of 35 degrees Celsius or higher, such as the internal body temperature of an average human. The hatched eggs release spores (referred to as SCP-XXXX-2) which spread through the body until they reach the intestines. Once there, they take root and attach to nearby blood vessels and nerve endings, switching off any pain impulses which would alert the host to the ensuing infection and feeding off nutrients from the circulatory system. When the spores have grown to a sufficient size, the larval stage of SCP-XXXX (referred to as SCP-XXXX-3) hatches.
Instances of SCP-XXXX-3 initially feed off nutrients in the bloodstream along with SCP-XXXX-2, but later begin to consume the surrounding tissues as it increases in size. As SCP-XXXX-3 continues to grow it extrudes a number of hair-like follicles into the intestine to absorb nutrients from the digested food that passes through. Towards the end of its development, SCP-XXXX-3 will extend a proboscis into the host's aortic valve (see Addendum SCP-XXXX-02a) and latch onto the host's stomach with its newly-formed “head” (see Addendum SCP-XXXX-02b). It then enters its pupal stage, allowing for it to anchor more firmly into the internal organs. Once grown, the pupae molts and has become a mature instance of SCP-XXXX. The molt is passed through the intestines and expelled as waste.
Once the molting stage ends, the parasite begins to consume the small intestine. The aft end of the mature SCP-XXXX extends further into the small intestine while the remainder of its body releases an enzyme that fuses the intestine wall to the parasite's skin and slowly absorbs it, eventually replacing the small intestine entirely. Hosts have been known to exhibit discomfort and sickness during this timeframe, which lasts for between 2 to 5 weeks depending on the size of the host. Once the intestine has been fully replaced by SCP-XXXX, the parasite proceeds to fulfill the function of the small intestine to keep the host alive. After this point, a host may experience occasional discomfort but is otherwise outwardly unaffected by SCP-XXXX (see Addendum SCP-XXXX-01).
SCP-XXXX is hermaphroditic and does not need to be in contact with another parasite in order to reproduce. Reproduction occurs after a brief period of extended feeding, which is followed by disgorging of several dozen eggs into the large intestine. During some reproductive periods seen in human hosts, SCP-XXXX is capable of hatching the eggs it produces internally, and distributing the spores into the circulatory system of the host so that infestation through exchange of bodily fluids may occur.
Infestations of SCP-XXXX are difficult to detect for the above reasons, doubly so when dealing with human hosts. While humans cannot support the same number of parasites as larger mammals, they are capable of hiding their infection from peers and field agents. If an infectee is located after initial infection or during the larval growth stage, the parasite may be removed with a ██% chance of complication and death, compared with the ██% for advanced infection. In some humans, evacuation may occur prior to death (see Addendum SCP-XXXX-3). In the event of this, the host will initially survive, but death normally occurs within 72 hours due to a combination of internal hemorrhaging and organ damage.
Addendum SCP-XXXX-01: While the hosts of SCP-XXXX can provide indefinite support for them, in the event of a host’s death they will evacuate the body through the nearest available orifice and seek out a suitable environment in which to survive. Reasons for host death include oxygen starvation, organ destruction, internal bleeding and heart attack, though a more recent proposal suggests that death is triggered via an enzyme release to kill the host’s nervous system. If this theory is correct it could mean that the evacuation of the parasite is a normal part of its life cycle, but it has not yet been observed in human hosts.
Addendum SCP-XXXX-02a: The proboscis in the aortic valve is used primarily to release enzymes and chemicals into the host’s bloodstream to condition its behaviour, and grants no nutrients to the parasite. Hosts to SCP-XXXX have been observed to go through cycles of intense feeding to either supply nutrients to the dominant parasite within or to sustain a fresh growth of SCP-XXXX-2.
Addendum SCP-XXXX-02b:During an outbreak in █████, ████████ it was discovered that a bovine host was supporting seven fully developed and one partially-formed parasite in its stomach cavity. As of ██/██/████, the support of multiple parasites has been noted in a minimum number of human infestations and is considered to be an uncommon occurrence.
Addendum SCP-XXXX-03: On 13/04/20██, the town of ████, ██████ was quarantined when evidence of SCP-XXXX infestation was discovered. Twelve of the townspeople were found to have been affected, and of these eleven were isolated and terminated. The single remaining subject was taken to Site-12 for study, and when sedated for a general medical biopsy the subject underwent cardiac arrest before the biopsy could begin. While resuscitation was begun, the instance of SCP-XXXX within the subject extruded itself from the navel and wrapped around the lead surgeon's arm. The instance of SCP-XXXX was quickly eliminated with no infestation of staff. Autopsy of the affected subject determined that the instance of SCP-XXXX had burrowed through the abdominal tissues and constricted around the subject's heart, inducing cardiac arrest. Subject had subsequently died due to toxic shock from its ruptured stomach lining.
Addendum SCP-XXXX-04: Despite the resemblance to various organisms within the animal kingdom, analysis on genetic samples recovered following the infestation in ███████ revealed the presence of four additional nucleobases within the DNA of SCP-XXXX. These pairings have presented the possibility of SCP-XXXX being a non-naturally occurring organism. Further investigation into its origin are being undertaken.

Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: Specimens of SCP-XXXX-2 that have been selected for study must be separated into blocks of 250 grams or less before being vacuum-sealed into plastic shrouds and kept in refrigerated storage. These specimens must be kept at temperatures of -10C or lower, with canisters of liquid nitrogen to be kept on-site for emergency cooling. When handling SCP-XXXX, researchers must use Level D protective suits and undergo standard decontamination process at the end of each session, and failure to abide by this will result in disciplinary action. Individuals exposed to SCP-XXXX without protection must be kept in quarantine until it can be determined that any contamination has occurred.
Specimens of SCP-XXXX that are discovered in the field must be isolated and secured; all instances are to be quarantined in a manner similar to biological agents that offer a significant hazard. This is required to keep potential active specimens contained and to aid in the presenting of cover stories. Should mass contamination of an area occur, sterilisation of the affected and surrounding area may be required.
Description:
SCP-XXXX-2 is a polycrystal silicon compound, first documented by the Foundation when it was uncovered in a coal mine in ███████. It has since been located at multiple sites worldwide and is mostly relegated to rock strata from the Changxingian age of the Permian period, though occurrences in other rock strata have been identified (see Addendum 01 for more details).
In its inert form SCP-XXXX resembles bituminous coal, though it is noticeably heavier and brittle. When sufficiently heated it begins to lose its molecular stability and collapses into a fine powder. After a period of between █ to ██ minutes, provided it has not been dispersed, the collapsed powder will begin to clump together and reform its solid shape. In this state SCP-XXXX is easily dispersed and on several occasions has been exposed to both wildlife and civilian populations. At room temperature or lower, specimens of SCP-XXXX will enter an ‘active’ state and are capable of simple movement, achieving this by shifting particles on the underside of the specimen. Studies have shown that active specimens show a basic level of pattern recognition and will move in the direction of materials with high silica content, if said objects are within three (3) metres of the specimen.
Upon reaching the object the specimen will spontaneously destabilise and spread across the object, covering as much of its surface area as possible before grinding against the covered surface and gradually breaking it down; minerals within the object are then dissolved and absorbed once exposed. When not presented with appropriate materials, an active specimen of SCP-XXXX gradually loses mass at a rate of approximately █ grams per week and is rendered permanently inert after a mean average of ██ weeks.
Exposure of SCP-XXXX to open skin results in irritation localised inflammation of the affected area, in both active and dispersed forms. Inhalation of dispersed particles particles of SCP-XXXX will normally lead to long-term respiratory diseases similar to emphysema and mesothelioma. In severe cases the inhaled particles will begin to reform within the lungs and cause severe trauma and, shortly afterwards, death of the affected.
Addendum 01: Samples of SCP-XXXX have been identified as occurring at the following strata: the Rhaetian age of the late Triassic, the Changxingian age of the Permian, the Famennian age of the late Devonian, and the Hirnantian age of the late Ordovician. All occurrences predate anoxic shale and disappear from subsequent layers.
Addendum 02: Testing has revealed that specimens of SCP-XXXX are vulnerable to extreme temperatures of -███ and ████ degrees Celsius. When exposed to these temperatures specimens will be rendered permanently inert; due to the greater degree of control over liquid nitrogen and the significantly lowered risk of dispersal of particles, the use of fire and high-temperature combustibles in neutralising active specimens of SCP-XXXX is highly discouraged.

Incident Report SCP-XXXX-07
Date: 05/07/19██ - 17/08/19██
Location: Globotnyk Coal Mine, ███████
Description:
At approximately 09:20 am, July 5th, the Eastern shaft of the Gobotnyk coal mine suffered a sudden explosion and was sealed in the subsequent cave-in. 12 miners were killed in the initial collapse, and at least 30 were injured to varying degrees; the worst injured were taken to the local hospital while those without serious injury were treated on-site and returned to their quarters.
At 17:30, miner Sergei Uralovich collapsed. He had been lightly injured in the blast but it was quickly discovered that he was suffering a number of bizzare wounds. The exposed skin on his arms had been scraped raw so that it was "…as red as a tomato" and within half an hour seemed to melt from the underlying muscles. At 19:40 he suffered a seizure and expired shortly afterwards. On autopsy a quantity of small rocks and coal dust was discovered in his branchial tract and lungs, which had undergone severe damage and hemorrhaging.
At approximately 04:35 on the 6th, three of the injured miners underwent a similar process to Uralovich, dying from severe internal haemorraging. Autopsies revealed that the internal organs of the deceased were mostly destroyed and large quantities of SCP-XXXX had been packed within the chest cavity and gut. Initial medical checks of the deceased showed they had suffered no internal injuries and had sustained mostly superficial injuries.
At 13:12 on the 8th, Uralovich's body was discovered to have undergone a process similar to extreme liquefaction. Much of the body's soft tissues had been destroyed and the remains were covered by a large quantity of SCP-XXXX. When attempts were made to move the body it was discovered that up to ██% of the remaining tissues and skeleton had been consumed by SCP-XXXX and subsequently lashed out and injured █ members of medical staff. Eyewitness reports stated that the specimen was able to "fire" small shards of material at medical staff and caused severe injury to those it struck.

Item #: SCP-####
Object Class: Safe
Special Containment Procedures: SCP-#### is to be kept inside a 2x1x1 metre steel sarcophagus at all times, with an average thickness of 5 centimetres per side. The upper plate of the chamber is removable and must be kept locked in place with four (x4) cam locks, in addition to two (x2) crossbar bolts placed longitudinally. The locks require daily testing, to be performed between 0800-1800 hours; any failures are to be reported and repaired immediately. SCP-#### may be removed for study between these hours, but not without approval from O5-█.
The sarcophagus of SCP-#### is to be kept on base at Site-██ and monitored at all times with cameras and motion sensors. Any anomalies detected are to be reported immediately, followed by the lockdown of the sarcophagus’ containment. Subsequent investigation and analysis are to be conducted between 0800-1800 hours; all staff found attempting to enter the containment area before or after these times will be subject to disciplinary action.
Description: SCP-#### is the corpse of a Caucasian male, age unknown, discovered on ██/██/████ in Demecser, Hungary. The subject appears to have suffered from anaemia and severe muscular dystrophy prior to death. Autopsies conducted on the subject have failed to determine the cause(s) of its condition but have revealed severe blood clotting in both the eyes and the circulatory system. The subject first came to the attention of the organisation after a series of attacks on both farmers and livestock in rural Hungary and was captured after a lengthy pursuit by field operatives (see Addendum 01).
Between 1900-0700 hours (local time, see Addendum 02) the subject will reanimate and, unless restrained, will seek out the nearest living mammal to its position and feed on its bone marrow; given enough time, up to 90% of the victim's marrow will be consumed. Upon finishing, the subject will continue to hunt until shortly prior to 0700 hours, at which point it will attempt to seek out an isolated location before returning to an inert state. The subject exhibits no response to pain or physical stimuli and testing has revealed a lack of brain activity during its animate state; as a result it is considered to be non-sentient (see Addendum 03).
The subject exhibits disproportionate strength in comparison to its lack of muscular tissue, and has been observed to be capable of tearing through Kevlar body armour under laboratory conditions. Experiments have shown that whilst exhibiting a preference for human tissue, the subject will consume any mammalian samples in its vicinity. Attempts to feed it avian, reptilian and amphibian samples have so far been unsuccessful. Regular feeding has been observed to improve both the subject’s muscle mass and skin tone, granting it a healthier appearance.
Addendum XXXX-01: Field Agent Coulson was injured during the operation but despite severe trauma to the anterior muscles of his right thigh, he showed no sign of physical discomfort for approximately 19 hours, at which point sensation gradually returned. Tests to determine the potential anaesthetic properties of SCP-#### are pending.
Addendum XXXX-02: The time of reanimation roughly corresponds to the local timezone. It has been proposed to keep the subject moving through time zones to keep it in its inanimate state, but due to logistical reasons this is seen as unreasonable.
Addendum XXXX-03: During its initial capture, the subject was observed to be capable of speech and apparent emotion. Subsequent testing has revealed a limited range of responses and actions, with little to no problem-solving ability. It has been proposed that the subject is able to utilise memories from its victims to make it a more efficient hunter, but is otherwise incapable of complex thought.

Special Containment Procedures: All instances of SCP-XXXX are to be taken offline and replaced with an inert replacement page following discovery. Instances do not need to be saved and may be deleted. Original page is stored in the computer mainframe at Site-██ for study and may be accessed with permission
Description: SCP-XXXX was first discovered by Agent Cooper on 19/03/20██ while browsing the website [REDACTED] when off-duty. It manifests as a trivia page for the 1995 film "Billy Madison", starring Adam Sandler, and is visually identical to other trivia pages found on the site.
Addendum:
Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures:
Description: SCP-XXXX is a Caucasian male, age 47, standing 172cm tall and weighing approximately 81 kilograms.
Addendum:
Foreword: On date 04/05/20██, SCP-XXXX was walking to the cafeteria of Site-█ when he approached a female staff member and proceeded to excise a benign tumour from the staff member's back, taking approximately 01:43 minutes to do so. After the staff member was examined and found to be physically unharmed, the subject was questioned by Doctor Charles Winnick.
<Begin Log, 19:32>
Dr Winnick: Let's get started.
SCP-XXXX: Of course.
Dr Winnick: Do you remember anything of the procedure you just carried out?
SCP-XXXX: Yes.
Dr Winnick: Describe it to us, please.
SCP-XXXX: Well, I remember the patient entering my office and requesting assistence with an ache in her back. I performed a basic analysis and discovered a lump between the left scapula and third thoracic vertebrae, and determined that it was a subcutaneous lipoma that was applying pressure to a nerve close by and thus causing her much discomfort. I found the depth of the lipoma to be unusual so I recommended to her that she return for a biopsy to accurately discover the requirement of surgery.
Dr Winnick: I see. How long ago did this take place?
SCP-XXXX: I'm not sure, unfortunately. I would say between three and four weeks ago? The biopsy was carried out a week later and confirmed the presence of the lipoma, and the procedure was carried out earlier today, as you are aware.
Dr Winnick: Yes. Can you tell us the name of your patient?
[SCP-XXXX pauses for several seconds.]
SCP-XXXX: …I apologise, I cannot recall her name.
<End Log, 19:34>
Closing Statement: SCP-XXXX was informed later in the interview of the nature of the procedure and appeared confused, but remained calm and later joked about it with Dr Winnick. The possibility that the subject is unaware of his abilities seems more likely in light of these events.

Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: Samples of SCP-XXXX must be kept in a Class-3 biohazard containment area, with appropriate safety protocols to be undertaken
(seriously, though, this part has been annoying so I'll fix it up later)
Description: SCP-XXXX is a parasitic organism which manifests itself in the reproductive organs of mammals. Most documented incidents involving the parasite have been restricted to cattle and populations of grazing animals found in rural areas, but in all cases of outbreak the possibility of cross-species contamination has been a significant risk.
In order for infection to occur, the potential host must have physical contact with spores from a mature specimen of SCP-XXXX. Due to the unusual nature of the parasite, the most common form of physical contact comes from sexual intercourse; though other methods of physical contact are possible to pass on spores, they have a much lower rate of successful infection.
Prior to copulation the parasite releases spores into the genitals of its host, which then infect the mating partner. Once inside the reproductive organs of the mating partner, the spores (referred to as SCP-XXXX-1) take root and begin to attach themselves to nearby blood vessels and nerve endings, switching off any pain impulses which would alert the host to the ensuing infection and feeding off nutrients from the circulatory system. When the spores have grown to a sufficient size, the larval stage of the primary parasite (referred to as SCP-XXXX-2) begins to grow.
This larval stage of SCP-XXXX-2 initially feeds off nutrients in the bloodstream along with SCP-XXXX-1, but later begins to consume the surrounding flesh as it increases in size. As SCP-XXXX-2 continues to grow it wraps around the small intestine of the host, extending a number of hair-like follicles into the intestine to absorb nutrients from the digested food that passes through. Towards the end of its development, SCP-XXXX-2 will extend a proboscis into one of the two arterial valves of the heart (most commonly the aortic valve) and latch onto the spinal column of the host with its newly-formed “head”. It then enters its pupal stage of development and goes dormant, allowing for the host to heal any injuries it suffered during the growth cycle and thus anchoring the parasite to its internal organs.
Once the pupal stage ends and the fully-formed SCP-XXXX-2 moults, the parasite begins to exert control over the behaviour of its host, forcing it to mate, consume particular foods and materials, and defend immature hosts when needed. As the parasite is hermaphroditic and does not need to be in contact with another in order to reproduce, the urge to mate is most likely a behaviour instilled in the host to cause as many infections as possible. The proboscis in the aortic valve is used primarily to release enzymes into the host’s bloodstream to condition its behaviour, and grants no nutrients to the parasite. Hosts to SCP-XXXX have been observed to go through cycles of intense feeding to either supply nutrients to the dominant parasite within or to sustain a fresh growth of SCP-XXXX-2. During an outbreak in █████, ████████ it was discovered that a bovine host was supporting seven fully developed and one partially-formed parasite in its stomach cavity.
While the hosts of SCP-XXXX can provide indefinite support for them, in the event of their death the parasites will evacuate the body through the nearest available orifice and seek out a suitable environment to survive. Possible reasons for host death include oxygen starvation, organ destruction and heart attack, though a more recent proposal suggests that death is triggered via an enzyme release to kill the host’s nervous system. If this theory is correct it could mean that the evacuation of the parasite is a normal part of its life cycle.
Infestations of SCP-XXXX are difficult to spot for the above reasons, doubly so when dealing with human hosts. While these cannot support the same number of parasites as larger mammals, they are capable of hiding their infection from peers and field agents. If an infectee is located after initial infection or during the larval growth stage, the parasite may be removed with a ██% chance of complication and death, compared with the ██% for advanced infection. In some humans, evacuation may occur prior to death; see Addendum SCP-XXXX-2b for more details.
