Item #: SCP-5798
Object Class: Keter
Special Containment Procedures: All live instances of SCP-5798 are to be contained on Site-114 within a modified Keter humanoid containment chamber (hereby referred to as primary containment), the walls of which should be coated in approximately two (2) centimeter thick acid-resistant steel. CCTV equipment is installed in the north-eastern and south-western corners. Two (2) meters of empty space are to be allocated between primary and secondary containment.
Secondary containment consists of suspending all live instances of SCP-5798 within a block of solid transparent substance (currently clear acrylic resin).
This block is to be at a height of at least three (3) meters, with one armed security guard stationed immediately outside initial containment at all times. An eight-digit passcode can be obtained from the current Site-114 director in order to bypass primary containment.
Secondary containment is to be regularly examined for damages. Movement and activity of any kind is to be noted, and the current Site-114 Director is to be informed at the earliest possible convenience.
Experiments involving the use of live SCP-5798 instances are strictly prohibited without approval from at least two personnel of Level-4 security clearance or above.
Description: SCP-5798 denotes a species of sapient Category-5 biological entities of currently indeterminable origin, though tissue samples indicate the presence of Silkie chicken, chimpanzee, stoat, mussel, adder, and human DNA. They are typically hairless, stained with a thin layer of an albumin-like excretion, and stand at an average of 2.9 meters. Its weight averages 780 kilogram for a matured instance, and 360 kilogram for a hatchling. Autopsy has determined that the cervical vertebrae of a mature SCP-5798 instance is composed of cartilage, rather than bone. This enables the neck and throat to twist and dislocate to around 340° in either direction, aiding their unusual reproductive cycle.
SCP-5798 are opportunistic hunters, engaging with live subjects within a radius of 0.6 kilometers surrounding hatchlings that have not yet reached full adolescence. Average speed is recorded at twenty-five (25) km/h. Upon contact with human or animal subjects, SCP-5798 will proceed to [REDACTED], liquefying internal organs and bone structure. A suitable cadaver is then transferred within range of the closest hatchling.
SCP-5798 produces large eggs of an off-white coloration and rubbery appearance. An egg will pass through the entity's digestive track, esophagus and eventually out via the mouth, followed by a viscous red substance (first thought to be a form of placenta, chemical breakdown has determined it to be a highly corrosive material.) SCP-5798 shows extreme distress throughout the process, with personnel describing the sound as 'not dissimilar to a scream'.
SCP-5798 produces its eggs to fill unoccupied space. There is no known limit to the number of eggs SCP-5798 is capable of producing, and the standing theory is as follows: given enough time, a single instance could singlehandedly perform an LK-Class species transmutation scenario. The termination of a live instance can be achieved through a variety of equally effective methods- SCP-5798 has proven to be around as resilient as a standard human subject. However, complete eradication has proven difficult, as all instances of SCP-5798 (regardless of age) carry one egg within a specialized stomach-like organ upon birth, assuring that one living instance will persist through even ordinary means of constant and lethal assault. This biological phenomena is presumed to be, in itself, anomalous in origin.
A single SCP-5798 egg can bear a tremendous amount of resilience, maintaining its form and purpose even following continual subjection to:
- Extreme blunt-force trauma.
- Pressure exceeding 180,000 psi.
- High-precision blades (serrated and non-serrated).
- Long-term acid exposure.
The application of plastic explosives was considered, but quickly rejected by higher administration. Heat is a primary component in the growth and development of SCP-5798's eggs, and Foundation Researcher Pwygh-Bythell was particularly apprehensive towards the idea, believing it would almost certainly result in a second containment breach.
SCP-5798 was issued Keter classification on 10/6/2017 following a containment breach. SCP-5798's prior containment method (a sedated water bath) was disassembled, and replaced with a revised containment procedure as listed above.
