SCP-1264 is maintained by a crew that has been designated SCP-1264-A. Each fit inside a US Navy standard rubber diving dress and are equipped with a Mark V diving helmet and weighted boots. SCP-1264-A are headless humanoid entities closely related to sea cucumbers (see autopsy report). SCP-1264-A are also connected by a flexible arterial cord roughly 90 meters long that is in turn connected to SCP-1264's interior. SCP-1264-A also secrete a strong adhesive through their gloves that act as a water-proof sealant, binder, filler, and cement in order to maintain the structural integrity and buoyancy of SCP-1264.
