A little on the SCP itself:

Item #: SCP-3000

Object Class: THAUMIEL

Description: SCP-3000 is a massive, aquatic, serpentine entity strongly resembling a giant moray eel (Gymnothorax javanicus). The full length of SCP-3000 is impossible to determine, but is hypothesized to be between 600 and 900 kilometers. The head of SCP-3000 measures roughly 2.5m in diameter, and sections of the body proper are as large as 10m in diameter.

SCP-3000 is typically a sedentary creature, only moving its head in response to certain stimuli or during feeding. The majority of its body is located in and around the Ganges Fan, and rarely moves at all.

SCP-3000 is carnivorous, and despite its sedentary nature is capable of moving quickly to dispatch prey. Despite its size, it is hypothesized that SCP-3000 does not require sustenance to maintain its biological functions. While SCP-3000 excretes a thin layer of a viscous, dark grey substance classified as Y-909 through its skin as it consumes prey, the end result of its digestive processes is currently unknown.

SCP-3000 is a Class VIII cognitohazardous entity; direct observation of SCP-3000 may cause severe mental alterations in viewers. Individuals who directly observe SCP-3000, as well as any individuals within an uncertain distance of SCP-3000, experience inexplicable head pain, paranoia, general fear and panic, and memory loss or alteration.
