Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: SCP-XXXX is to be contained in a 10 m x 10 m x 10 m cell with speakers embedded in all four walls. The speakers are to be turned to full volume at all times, even when not in use. When SCP-XXXX enters an irritated state, a 50kHz audio frequency must be played for ten seconds straight, outside of the human hearing range but, evidently, powerful enough to disable SCP-XXXX. If it is found to be necessary, the frequency may be raised to 75kHz by a site director, but only under direct orders from O5-█. Video and audio surveillance into SCP-XXXX’s cell is required at all times.

Description: SCP-XXXX is an eyeless, noseless humanoid creature measuring 2.13 meters in height. SCP-XXXX's arms are extremely similar to those of a human, with the exception of its fingers, which bare 0.32 meter long claws. SCP-XXXX frequently walks on its hind legs, though it chases prey on all fours. Its hind legs are similar to a humans, though they are skinnier and appear to show signs of genu recurvatum.1 This formation is advantageous when SCP-XXXX gives chase. SCP-XXXX has an elongated, flexible neck, permitting it to switch between bipedal and quadrupedal navigation at will.

SCP-XXXX was captured in the [DATA EXPUNGED] cave system by Mobile Task Force Zeta-9, following the discovery of two dead explorers in 19█. All attempts to communicate with SCP-XXXX have failed, leading Dr. Waltz to reject the possibility that SCP-XXXX is an infected human (see interview attempt A). Communication with SCP-XXXX has been achieved (see interview attempt B). Consensus states that SCP-XXXX is not human, though doubt has arisen amongst several key personnel.

Skin on the head is a translucent grey color, wrapped around what appears to be the face of a caucasian male. The torso is covered in what appears to be brown body armor. Whether this armor is extraneous or natural is unknown. SCP-XXXX is believed to be a member of a species, tentatively referred to as Eclochs, though as of [DATA REDACTED], no signs of similar creatures have been reported.

SCP-XXXX is an extremely capable swimmer. It can holds its breath for several hours at a time and swim at speeds exceeding 60 km/h. SCP-XXXX navigates and hunts using echolocation, primarily between 2200 hours and 0600 hours, though if and how it keeps track of time remains unknown. Its hearing serves as its primary sense, though it has infrequently utilized touch for navigation.

SCP-XXXX uses its aforementioned claws as its primary means of attacking and killing prey, which includes (but is not limited to) olms, scorpions, spiders, fish, beetles, and salamanders. Feeding trays should consist of these creatures as they are available, and feeding will be limited to one tray of food every six hours.

When irritated or provoked by any sound, SCP-XXXX dashes towards the perpetrator, hereafter referred to as SCP-XXXX-1, at a speed of 110 km/h, letting out a high-pitched squeal that can be sustained for up to 180 seconds. This squeal instantly incapacitates SCP-XXXX-1 and any other living beings within a 60 m radius, and also aids SCP-XXXX in locating SCP-XXXX-1. Specially designed sound cancelling headphones are required for all personnel within 150 m of SCP-XXXX’s cell at all times. Checkpoints on both sides of this radius must be constantly monitored and stocked with headphones. Checkpoints are required to have five security officers working in six hour shifts, to ensure their utmost efficiency. Class E personnel are not permitted to be within 300 m of SCP-XXXX's cell unless there is a breach.
