 Item number SCP-525 Object Class Euclid Special Containment Procedures Outside of testing conditions, the individual components of SCP-525 must be stored in separate sealed containers. No more than six components may be stored in the same room or within 15 meters of each other. All currently existing components are accounted for at storage site 23 in lockers f*** to f***. Only Class D personnel are authorized to handle SCP-525. All supervising staff must wear protective eyewear during testing. Description SCP-525 consists of multiple disjoint arthropod legs, 10 to 15 centimeters in length. DNA identification has been inconclusive, but the closest match so far is to the brown recluse spider, loxosceles reclusa. The base of each leg is in several minute hooks capable of perforating flesh. SCP-525 is covered in short, fine hairs and is quite brittle. When alone or in proximity with fewer than six others, SCP-525 is inert. When eight components of SCP-525 are brought within range of each other, approximately 0.6 meters, the legs will immediately crawl into a group and attach themselves into a single entity, referred to as 5251. At this stage, the speed of its locomotion greatly increases and it will attempt to make contact with the closest human or similar. When a suitable animal is found, 5251 will climb directly towards the animal's eye. Having centered itself over a socket, four legs will secure the eyelid, while the others extract the eye. Despite 5251's rapid movements, extreme care is taken not to damage the eye during the extraction. Data expunged, severing the optic nerves and central retinal vein. Once the eye is free from the original owner's socket, 5251 will implant the base of each leg into the eye. Close inspection shows that the hooks at the base extend, effectively rooting the leg in position. If allowed to remain, 5251 will lay what appear to be eggs in the socket of its host before climbing off. Even in possession of an eye, 5251 is no longer hostile and its movement is somewhat impeded. Curiously, 5251 does not respond to visual stimuli, suggesting that it does not use the eye for sight. Dissection of a chimpanzee eye taken by 5251 and retained for a period of one week revealed the formation of data expunged. After time, the eye dehydrates, eventually turning the same reddish color as SCP-525. After two to three weeks, 5251 will abandon the eye and begin to search for another. Addendum 525a 525 responds to most large to moderate sized mammals. Reptiles, fish and birds have provoked little response. Unexposed to crocodillus acutus, 5251 attempted extraction, managing to blind the animal but otherwise failing. Thereafter, all instances of 525 have not responded to crocodiles, even those not present at the initial experiment. Document number 525a Observation log of subject D-1548, after exposure to 5251. Work compiled by Dr. Weiss, dated 1. Medical staff on hand attend to D-1548, 14 ovoids resembling opaque toed eggs discovered embedded in the extraocular muscles, 3 are removed and sent to the research lab, D-1548 placed under quarantine. Week 2 D-1548's injury is healing as normal, eggs show marginal swelling, D-1548 does not display unusual discomfort, eggs stored in the lab have deliquest. Week 3 D-1548 complains of increasing phantom pressure in the socket, D-1548 demands a mirror to inspect the injury, request denied, muscle tissue is healed over and obscured the eggs. Week 4 D-1548 forcefully removes bandages and attempts to dig into the socket, is successfully restrained. 24 days after initial exposure, 11 fully formed components of SCP-525 erupt from D-1548's socket and begin to coalesce, data expunged.
