 SCP-575 appears to be an unknown form of matter, taking the form of a series of amorphous black shapes and structures. SCP-575 is difficult to observe, as it immediately dissipates when exposed to light. Current testing has been unable to identify if SCP-575 is organic or inorganic. Despite the lack of any visible nervous systems or observable organic components, SCP-575 displays behavior consistent with an active consciousness. SCP-575 initially manifests in total darkness. How this occurs is unknown. However, tests have shown a variable mass of SCP-575 forming when data expunged variable, along with a time frame. SCP-575 is capable of floating and can alter its density, allowing it to pass through very small openings.
