Item #: SCP-1563
Object Class: Euclid
Special Containment Procedures: Specimens of SCP-1563 are contained in a sealed vivarium at Bio-Containment Site 84 built to emulate a temperate forest environment, and ten Odocoileus virginianus (White Tailed Deer) are to be released into the cell on a weekly basis. Any further specimens of SCP-1563 found in the wild are to be terminated. (See Addendum-1)
Description: SCP-1563 is a predatory organism resembling plastic property markers commonly used in rural areas. Specimens of SCP-1563 usually exhibit pink coloration (with orange and blue coloration being recently discovered), though coloration of all types is hypothesized to be possible. SCP-1563 has very durable and sharp tooth-like structures measuring 1.5 mm covering the ventral side of its body. These teeth are used to puncture the neck of its prey.
SCP-1563 exhibits behavior of ambush predators, attaching itself to trees or other standing wooden structures. When a prey animal passes by, SCP-1563 will detach and leap onto its target, then wrap around its prey's neck and strangle it to death before puncturing its neck using sharp teeth and feeding on its blood. SCP-1563's preferred prey appears to be Odocoileus virginianus (White-Tailed Deer) and as such poses minimal threat to humans unless provoked or malnourished. SCP-1563 is able to survive for up to two weeks without food.
SCP-1563 has two organs; a small capillary system which is presumably used to process and distribute the consumed blood throughout the body, and the teeth, which are attached to the capillary system and used to absorb blood as well as kill prey. SCP-1563's mean of locomotion is unknown, as no muscle tissues have been discovered. SCP-1563 has an extremely durable cell structure composed of what appears to be a 'double'-cell wall1, with the second cell wall forming a tight bond with adjacent cells. SCP-1563 reproduces asexually. The specimen will split itself in two, and hunt smaller prey such as rabbits until it grows to a sufficient size. At that point, it will resume hunting White-Tailed Deer.
SCP-1563 will occasionally secrete a yellowish-brown substance, presumably waste. The excretions halt approximately 1-2 hours after they begin.
It should be noted that on touch, there is no discernible difference between SCP-1563 and a plastic property marker.
SCP-1563 came to the Foundation's attention following multiple reports of deer strangled using property markers in ████████ ██████, Virginia. Undercover Foundation agents investigating the incidents were able to identify the anomalous entity responsible, and a containment team was able to secure several specimens and transport them to Temporary-Storage Site ██.
