 Item Number SCP-863 Object Class Safe Special Containment Procedures SCP-863-1 is to be contained in a 2 meter by 2 meter enclosure and provided with nutrition as detailed in nutritional chart 86311. Due to its low risk of breaching containment, SCP-863-1 is to be kept under guard by one member of security. In the event of limb loss, SCP-863-1 is to be provided with a replacement from a similarly proportioned crab. SCP-863-2 is to be contained in a 6 meter by 6 meter enclosure and provided with nutrition as detailed in nutritional chart 86321. SCP-863-2 is to be kept under guard by two members of security. In the event of limb loss, SCP-863-2 is to be provided with a suitable replacement. SCP-863-3 is to be contained in a 10 meter by 10 meter enclosure and provided with nutrition via robotic arm as detailed in nutritional chart 86331. SCP-863-3 is to be kept under guard by six members of security at all times. No personnel are to enter SCP-863-3's containment enclosure. In the event of limb loss, SCP-863-3 is to be provided with a cadaver as replacement. Any specimens of SCP-863 found in the wild are to be destroyed. Description. SCP-863 is a species of crab commonly found in areas of SCP-863 specimens when first born, measure roughly 3 centimeters in height and 1 gram in weight, but are capable of growing up to sizes of data expunged. When fully grown, specimens superficially resemble the Japanese spider crab. Specimens of SCP-863 are born without limbs and undergo a process in which they utilize the limbs of other organisms or even whole organisms in lieu of their own. From birth, SCP-863 move themselves across the ground by sliding, using several tendrils attached to their limb joints. When specimens of SCP-863 locate a suitably sized limb or organism, they will puncture it using their tendrils, which will then retract and slot the organism or limb into the limb joint. Using a series of electrical pulses, SCP-863 will then manipulate the limb or organism's nervous system. This process is not perfect and the utilized limb or organism will typically twitch or jerk periodically. Specimens of SCP-863 are highly territorial and larger specimens can cause severe injuries or death when provoked. Groups of SCP-863 have been observed to, on occasion, actively hunt for other organisms to remove limbs from. Larger specimens will simply utilize these organisms' whole cell, as their limbs would not be suitable for specimens of that size.
