 SCP-749 is an apex predator, approximately 3 meters long, with 2 to 300 pairs of legs. Each individual SCP-749 possesses powerful force opioles, which secrete a powerful acidic compound. SCP-749 demonstrates a predilection for hunting during rainstorms, and appears to be familiar with urban settings. These preferred hunting methods consist of climbing up the walls of domiciles, using its force opioles to gain entry, usually by boring a hole through a wall or window, then feeding upon sleeping individuals within. SCP-749 shows a marked intelligence in evaluating potential prey. In all reported SCP-749 attacks, the creature fed upon the smallest unaccompanied individual, and its feeding habits and containment continue to support this conclusion of intelligence.
