A Spotted Dogfish.

Item #: SCP-1XXX

Object Class: Euclid

Observation Procedures: SCP-1XXX is to be tracked by Mobile Task Force Rho-16 (aka "There's Wally") 24/7. All recordings of and humans who have reported sighting SCP-1XXX are to be removed if possible. SCP-1XXX is to be guided away from any foundation sites and human settlements.

Description: SCP-1XXX appears to be a member of the species Canis lupus familiaris, identified as the breed Greyhound. SCP-1XXX has shown the ability to be impossible to "capture" in any definition.

Recollections of SCP-1XXX have been inconsistent in describing the SCP1. All recording devices will malfunction or become heavily corrupted when directed at SCP-1XXX. Every known attempt to contain SCP-1XXX have been met with failure. Descriptions of SCP-1XXX will vary. The SCP has been identified as 284 species of animal, 67 species of plant, 7 [DATA REDACTED] and 13 SCP objects. SCP-1XXX, although capable of being tracked, has no predictable movement patterns, and thus can only be tracked reliably by MTF Rho-16.
