Item#: SCP-4310

Object Class: Euclid

Special Containment Procedures: SCP-4310 instances are to be kept in dynamically lit rooms simulating day and night cycles, contained in separate heavily modified glass tanks approximately .76m x .3m x .3m. Tank lids are to be firmly clamped down, with the left and rightmost sides of the tank outfitted with heat and motion sensors. Interiors of the tanks are to perfectly resemble scenery of the South American rain forests, with fauna recovered from site of SCP-4310's recovery.

Any noticeable signs of agitation in SCP-4310 instances or cracks on the glass tanks are to be reported immediately so that staff may play "The Lullaby" within the related room. "The Lullaby" is to be played twice a day in the time frames of 0800-1000, and 2000-2200.

If more than one instance of SCP-4310 is in a single tank actions are to be taken immediately to safely remove the extra instances and relocate them to individual tanks. Footage must be reviewed afterwards for premature breeding or SCP-4310-1 subjects.

SCP-4310-1 subjects if discovered are to be immediately contained in a 12m x 12m cell with only Level-3 staff permitted access to communicate with and/or study SCP-4310-1 subjects. Termination via ignition is mandatory after a two day period.

Description: A SCP-4310 instance is a solitary, parasitoid invertebrate whose make-up closely relates to that of a common tapeworm, with a diameter of approximately .03 m, a length that ranges from 1.82 m to 5.48 m, and a mouth the size of a small hypodermic needle in which it uses to drag itself and attach to human hosts.

The organisms display a strong interest in humans with little to no interest in anything else, including its own species, displaying extreme distress and agitation when around these other organisms. When agitated SCP-4310 will begin to aggressively contort its body and actively try to separate itself from the other organism through any means necessary, sometimes self-terminating itself in the process. This appears to be an instinctual response, due to data relating its reproduction cycle.

SCP-4310 instances continually seek out human hosts, when one is found it makes its way to the hosts naval cavity where it injects a numbing coagulant before proceeding to burrow in. The host either unaware or aware of the process will never feel it and no bleeding will occur, any attempts at premature removal all ended in SCP-4310 in hastening its incision or sometimes [DATA REDACTED]. After approximately four hours after incision, the host will experience immense pain in and around the incision point for about two hours, subjects detail the pain as, "like being drilled into." A black substance is usually seen leaking out of the hole at this point in the process. After the two hour period expires the incision point completely heals, leaving no trace of the prior events and the host seems to remember nothing of SCP-4310, effectively becoming SCP-4310-1.

SCP-4310-1 subjects do not appear to have any physical differences, but mentally the subject goes through vast changes due to possible anomalous properties of SCP-4310. The subject begins to display vast knowledge of everything in both the physical and metaphysical universe excluding SCP-4310. Subjects even display clairvoyant knowledge extending past our timeline, knowing events and situations before they even occur. SCP-4310-1 subjects are narcissistic and show extreme apathy to all things but itself, seemingly only spouting knowledge just to "show off." After two days pass the subject becomes noticeably bloated, although SCP-4310-1 subjects all claim that it has not changed physically whatsoever. At this point the gestation period for new instances of SCP-4310 occurs, an estimate [DATA REDACTED] per second being produced, causing extreme discomfort for the host, despite it never admitting this.

During the final phases, the host will remember SCP-4310 through unexplained means, proceeding to seek it out and "give life." Once found, the host will remove all articles of clothing, revealing several wriggling, fleshy sacks upon the host, filled with SCP-4310 offspring contorting in agitation and emanating an anomalous glow. SCP-4310-1 will begin to hum a lullaby to the found instance of SCP-4310 which will then [DATA REDACTED] before the host begins yelling about [DATA REDACTED] then subsequently having the sacks burst and release over [DATA REDACTED] offspring.

Addendum: The anomalous humming has now been designated, "The Lullaby," and upon some tests it seems to reduce SCP-4310 agitation outside of reproduction periods, however if used when an instance of SCP-4310-1 is close by it could lead to serious repercussions and a possible containment breach.

Personal Log of Dr. Grigs: Instances of SCP-4310-1 have even knowledge of other SCPs, staff members, hell even the O5 Council members! If this isn't some form of security hazard I don't know what is. But I won't question the decisions made, [DATA REDACTED]. We still don't know a lot about SCP-4310, I look forward to continued experimentation.
