Item #: SCP-2856

Object Class: Euclid

Special Containment Procedures: Instances of SCP-2856 are kept in a large terrarium in an isolated chamber at Site-26-C. The feeding system has been fully automated, and should deposit 10g of live crickets on a weekly basis. Researchers are to observe standard protocol for the handling of biohazardous macroorganisms. A specimen of Felis catus may be introduced into the terrarium should the total population of SCP-2856 fall below 5 instances, in order to facilitate reproduction.

Personnel displaying any degree of arachnophilia are to be immediately detained and quarantined, and are to be immediately euthanized, should they make contact with SCP-2856-2.

Description: SCP-2856 outwardly appear to be desert spiders of the species Stegodyphus lineatus. Instances of SCP-2856 exude specialized pheromones, which seemingly act as an aggregator. Regardless of the receiving organism's species, biochemistry, reproduction cycle and gender, it will invariably enter a state of extreme arousal, and may attempt to seek out the source. This desire can be easily resisted, and is completely reversible via removal and a brief quarantine. In non-sapient animals, this compulsion can be overridden by self-preservation instincts, should the organism encounter a threat to its safety.

Prolonged exposure to these pheromones can lead to an urge to physically interact with spiders and their silk. In humans, this is accompanied by an altered state of perception. Subjects viewing webs produced by any spider species report seeing words and phrases deifying arachnids. These hallucinations are not considered cognitohazardous, though subjects at this stage may need to be restrained to prevent attempts to make contact with SCP-2856-1. Other organisms suffering a similar level of exposure will likewise display a full disregard for their safety.

SCP-2856-1 is the designation for a substance, similar in composition to spiders silk, produced by the entities. The silk will be absorbed at the point of contact with living organic matter.2 This process somehow results in an egg clutch being sub-dermally implanted, which hatches instantaneously. The juvenile SCP-2856 will swarm the organism, converging on and around the oral cavity. The infected hosts are classified as SCP-2856-2.

Until their bodies have atrophied beyond use, subjects have been observed interacting with one another in a caring or nurturing manner. Even natural predator/prey relationships seem to dissolve, and non-sapient SCP-2856-2 instances show no aversion to human hosts. Hosts otherwise seem indifferent to their predicament, however they will become distressed and despondent should the juvenile SCP-2856 be removed from their person.

Autopsies of several SCP-2856-2 instances has revealed a foreign enzyme present in hosts that breaks down both adipose and muscle tissue, resulting in a slurry. The combined substance enters the digestive tract, and is automatically regurgitated by the host. The juvenile SCP-2856 will gather here, feeding on the substance as it is produced. This process seems to mimic matriphagic behavior typical of spiders in the Eresidae (velvet spider) family; and can last for two to three weeks as the host atrophies, before the enzymes begin liquifying vital organs.

SCP-2856 was discovered on 9/03/19██, following an investigation by the Israeli government into the reported disappearance of a Brazilian couple who had been visiting the country. Foundation agents embedded within the police force contacted nearby Site 26-C to assume control of the area once the anomalous nature of the situation was established.

Update: After several weeks of study to determine the colony's nature, MTF-Iota-11 ("Dune Raiders") was tasked with capturing several live specimen of SCP-2856 for relocation to Site 26-C. The remaining instances and their hosts were eliminated, and MTF-Iota 11 proceeded to search for any information regarding the source of the phenomenon.

Within the cavern on the edge of the settlement, task force members came across what is believed to be the origin point of SCP-2856. Items of significance that were recovered from the scene include:

• The desiccated remains of two human hosts to SCP-2856. They were later identified as the missing Brazilian couple, Felix and Rosalyn Guerra.

• A pair of passports for the couple, with entry stamps indicating travel of several European and South American countries.

• A wooden idol of a feminine humanoid figure with accentuated breasts. Carbon dating places the carving of the object c.140.

• An ornate copper basin placed on the ground before the statuette, containing a partly decomposed sheep's uterus, as well as mandragora root and over ₪2,000 ILS. A specimen of Stegodyphus lineatus was found crushed beneath the basin.
