Item #: SCP-940
Object Class: Keter
Special Containment Procedures: All known samples of SCP-940 larva are currently in containment. Systematic purging of SCP-940 adult samples from civilians is currently (as of ██/██/████) being spearheaded by a combination of Area-14 Research personnel and Mobile Task Force Omicron-7 ("Orkin"). Samples of Foundation strengthened █████-█-████████ (see documentation regarding 'Agent Blue') are in the process of being added to commercially available insecticides, which is expected to prevent any more 'wild' strains of SCP-940 from arising. All SCP-940 infectees are to be treated as Class 4 Biohazards, and are to be contained and transported under heavy sedation to Area-14, or otherwise terminated. Deceased bodies infected with any SCP-940 strain, regardless of developmental stage, are to be incinerated.
Description: SCP-940 is a parasitoid organism with some superficial similarities to troglobitic members of the class Arachnida. Adult specimens are highly agile and possess leg spans from four to seven meters; due to the difficulty in separating SCP-940 from their hosts (see below), average weight and body size are moot considerations. Each of their eight translucent legs is dotted regularly with six types of specialized sensory organs—IR-sensitive pit organs; ampullae of Lorenzini; compound and non-compound eyes sensitive to UV; and two additional organs of indeterminate function—and end in large tarsal claws, possessing scopulae and setules common amongst species of hunting spiders and allowing them to climb sheer vertical surfaces with ease. SCP-940 possess a radial nerve net similar to Asteroidea, or the common starfish, and no central nervous system; the possibility that SCP-940 rely on their host's brainpower for processing of external stimuli cannot be ruled out at this time.
Infection occurs following exposure to body fluids containing SCP-940 eggs and larvae. The lifecycle of SCP-940, from initial infection to maturity, is as follows:
Treatment with intravenous anti-parasitic compound is possible, if administered prior to infection advancing to Stage 3.
Addendum: Stage Six and above adult SCP-940 samples, when not attempting to conceal their identities, are extremely agile and capable predators. Through the use of their powerful limbs and multiple sensory organs, they are highly adept at evading capture; field agents are to be highly cautious and equipped with MOPP-4 gear at all times to prevent infection, and Foundation-issued nerve gas grenades for suppression purposes.
