Object Class: Euclid


SCP-XXXX within Cancer. Hover to enlarge.


SCP-XXXX during its 2014 manifestation. Hover to enlarge.

Special Containment Procedures: Remote monitoring of Beta Cancri has been assigned to Joint Research Task Force Phi-4 ("Zodiac Hunters"), composed of members of the SCPF Department of Essophysics and the Astronomical Phenomena Division. Extensive observation of SCP-XXXX is to occur during the astronomical summer, until JRTF Phi-4 determines that it has initiated an essophysical manifestation event. JRTF Phi-4 will then approximate its destination on Earth within one kilometer of accuracy using resources provided by the Department of Essophysics. In order to protect SCP-XXXX, the area of its manifestation must be restricted from civilian access until the essophysical manifestation event terminates.

Containment procedures for the mass extinction of crabs are presently being drafted and will be put into effect if SCP-XXXX is neutralized.

Description: SCP-XXXX is Beta Cancri, the brightest star in the zodiacal constellation of Cancer, and is theorized to be a large-scale essophysical anomaly embodying all animals of the taxological infraorder Brachyura: colloquially, marine and terrestrial crabs. SCP-XXXX's essophysical properties constitute any significant injury, emotional trauma, or large-scale containment efforts imposed upon it affecting crablife in an analogous fashion.

Although SCP-XXXX appears to have voluntarily manifested within baseline reality as Beta Cancri, it is still capable of projecting its form elsewhere in the universe during an essophysical manifestation event, usually as a mundane crab. Attempts to communicate with SCP-XXXX in any of its forms have been unilaterally unsuccessful.

SCP-XXXX was originally documented after it manifested in Navagio Beach, Greece, on 2012/06/19, at which time it presented as an Atlantic marsh fiddler crab (Uca pugnax). All subsequent manifestations have occurred annually on beaches during the summertime. The exact parameters for the selected locations are ambiguous, but it has been noted that recorded sites of manifestation have been clear of precipitation and possess generally warm temperatures.

All documented manifestation events have followed a similar process, recorded below.

  1. SCP-XXXX manifests on a terrestrial beach as an ostensibly non-anomalous crab. It is usually not noticed by beachgoers at this time, barring one manifestation where it presented as a coconut crab (Birgus latro).
  2. SCP-XXXX searches for a suitable nesting ground in the surrounding sand where it can bury its body. The criteria for this selection is poorly understood but is assumed to be related to the warmth of the sand and access to sunlight.
  3. SCP-XXXX gradually displaces the sand and settles into the deposit, using its claws to bury itself.
  4. Once SCP-XXXX is completely buried, it sleeps for a period of time not exceedingly 100 hours. If the beach experiences precipitation or a decrease in temperature, SCP-XXXX may relocate to a warmer environment.
  5. The manifestation event will terminate, and SCP-XXXX will return to Beta Cancri.

Addendum.XXXX.1: Overseer Consensus

Foundation Directive Alpha-3 ("Protect") necessitates the preservation of life and/or reality in the event of an XK-Class Scenario. The hierarchy of concern guiding this directive designates the preservation of individual species on Earth as a Σ-level priority under Directive Alpha-3.

In the event of an XK-Class scenario threatening reality and/or life at large, the Foundation will contain SCP-XXXX in a modified extradimensional containment chamber and protect it from being harmed. This can only be accomplished if the following conditions are met:

  • SCP-XXXX has manifested on Earth in a containable form.
  • The XK-Class scenario does not threaten extradimensional space.
  • The XK-Class scenario is both foreseeable and irrevocable.

If all these conditions are met, the Foundation will satisfy the Σ-level priority of Directive Alpha-3 and protect SCP-XXXX's containment at all costs. In this way, even though all higher forms of life may be destroyed, all crab life will be preserved.

The Department of Hypothetical Scenarios was established many decades ago to prepare for the end of humanity. However, the variety of life in our universe has caused our departmental objectives to be re-evaluated. There may come a time when humanity is stamped out — either by our own doing or that of an invading force — but it is not necessarily the case that all other forms of life will follow suit. In all recorded mass extinctions, complex life has fallen while simpler organisms have flourished. It is therefore our duty to protect all other forms of life, if our own is to perish.

We will soon begin constructing SCP-XXXX's containment chamber in an isolated extradimensional space, filled with as much beach as it can desire. If its containment becomes necessary, it will be safe, happy, and above all else: alive. And so long as that remains the case, we can expect that crabs as a taxological group will be much the same.

It may just be that the last bastion of life in this fatal universe is a tiny fiddler crab, hibernating on the beaches of Greece. And it is our duty as stewards of humanity to protect it.

Addendum.XXXX.2: Communications Update

On 2018/08/03, JRTF Phi-4 detected a radio message emitting from SCP-XXXX while it hibernated. Notably, the message was relayed in Morse code, similar to interstellar radio messages sent from Earth to deep space.
