Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: SCP-XXXX is to be kept in a large cylindrical tank 8 meters in diameter and 3 meters in height, providing a total volume of at least 140KL. The water in the tank must be kept at a temperature no lower than 20° and no higher than 30° Celsius. The salinity level should be as close to 35 g/L as possible to provide a specific gravity of 1.025. The inner walls of the chamber the tank is contained within should be lined with a layer of sheet-copper RF shielding.

SCP-XXXX should periodically be provided with live, assorted prey animals, cultured separately. Water filtered from the tank SCP-XXXX is held in should be sterilized before discharge into wastewater facilities. Any clones created from SCP-XXXX must be immediately destroyed if they show the ring structures characteristic of SCP-XXXX. Powdered tungsten and/or molybdenum should be provided to SCP-XXXX as requested by SCP-XXXX-3.

In the event of an XXXX-Lambda event, research staff assigned to SCP-XXXX are to be alerted immediately. Any statements made by SCP-XXXX-1 through 5 during an event are to be recorded via the radio receiver positioned outside the containment tank.. Statement and conversation archives are available to foundation staff with level-2 XXXX security clearance. During an XXXX-Lamba event, SCP-XXXX-1 through 5 may be interviewed by foundation staff with level-2 XXXX security clearance. Prolonged association with SCP-XXXX-1 through 5 is not advised.

Description: SCP-XXXX is a free-swimming flatworm of the species Pseudoceros dimidiatus. Morphologically, SCP-XXXX displays only two differences from standard members of the species: its dimensions are considerably larger than average members of its species and there are several thick rings of an unknown tissue at various points along its body. The rings have no obvious analog to any known biological structure. The rings are arranged in two parallel rows along the length of SCP-XXXX, each centered directly over the intersection between a transverse nerve and a ventricle nerve. Samples have been taken from the rings and analysis shows that the tissues are composed of very high levels of tungsten and molybdenum. These rings also emit a continuous radio signal, strong enough to be detected up to █████km from SCP-XXXX.

SCP-XXXX was discovered in the possession of the Alexandria Aquarium Marine Research Institute in Alexandria, Egypt. Records recovered from the site at the time of it's capture are not clear as to whether or not the Institute discovered the creature or created it in a lab.


Periodically, the radio signals emitted from SCP-XXXX fluctuate wildly for a five to ten minute span. These have been designated as XXXX-Lamba events. Transmissions from SCP-XXXX during these events appear to follow a logical pattern consistent with a broadcast message. Efforts to decipher the messages have thus far been unsuccessful.


On ██/██/████ Foundation agents recovered decryption software from the computer systems at the Alexandria Aquarium Marine Research Facility. The software has been used successfully to translate the radio broadcast from SCP-XXXX during an XXXX-Lamba event into a string of text in Arabic. The translated text has proven to be nothing more than trivial information regarding marine invertebrates. Other Lambda events have produced similar results. Monitoring of transmissions is ongoing.


A closer examination of the semantic construction of the transmissions indicates as many as five separate authors. These have been designated SCP-XXXX-1 through 5.


On ██/██/████, Foundation Researchers utilized a short range radio transmitter to send the following encrypted message on the same wavelength as that used by SCP-XXXX: ""من أنت؟" (Who are you?)" SCP-XXXX immediately initiated a return transmission of it's own. The message received, once decrypted read: ""أين يوجد لدينا دودة؟" (Where we have a worm?)" All regular SCP-XXXX transmissions have since stopped.

At this point, all regular SCP-XXXX transmissions ceased.


As of ██/██/████ SCP-XXXX-Lambda events have begun increasing in frequency. Any radio transmissions directed at SCP-XXXX produces an immediate response from either SCP-XXXX-1, 2, 3, 4 or 5, seemingly at random. Sample portions of several interview logs, translated to English for convenience, are attached..


On ██/██/████ SCP-XXXX resumed regular transmission. No XXXX-Lamba events have been observed since ██/██/████.


On ██/██/████ SCP-████ damaged the FR shielding surrounding SCP-XXXX during a short containment breach. While SCP-XXXX remains unharmed, it was able to broadcast uninhibited for eight hours.


As of ██/██/████ site-66 staff who have been in contact with seawater after ██/██/████ may not be assigned to SCP-XXXX. █ casualties.


As of ██/██/████ foundation staff who have been within █km of the ocean after ██/██/████ may not be assigned to site-66. ██ casualties.


As of ██/██/████ foundation staff who have eaten shellfish within the last six years may not come within ██km from SCP-XXXX. ██ casualties. SCP-XXXX transferred to Biological Research Area-12.


As of ██/██/████ seawater, shellfish, woodlice, persons or objects which have made contact with any of the above, and [REDACTED] may not come within ███km of Area-12. ███ casualties. Keter status pending.


As of ██/██/████ the remote optimization of [REDACTED] has ceased. ██ live specimens are in containment, and have been designated SCP-████ through ████. All SCP-XXXX transmissions have ceased. Keter status denied.
