Per 
SCP-XXXX-A upon discovery
Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: SCP-XXXX-A is to always be completely submerged in a 2x4x2 meters water tank filled with three kiloliters of water at least. The water must never be higher than the protection grid near the top of the tank in order to leave an air gap to make easier the recollection of SCP-XXXX-B instances. The protective grid must be completely closed at all moments, except when recollecting or for testing purposes1.
SCP-XXXX-A and -B instances are currently contained at the east wing in the undergound plant at Site-███. SCP-XXXX-B instances that have yet not found a host are to be contained in the adyacent test chamber until they either die, or are used to make SCP-XXXX-2 instances under the circumstances dictated in Protocol-909-Nerites. To avoid the spread of said SCP-XXXX-B instances throughtout all the plant, or even outside the Site, the air ventilation of the plant must be limited to the entrance point, and must only open each uneven hour for thirty (30) minutes. In case of malfunctioning of the air lock or low oxygen levels, each room is said to have at least ten (10) oxygen tanks, with the storage rooms and the panic room allowed to have thirty (30) oxygen tanks at much.
SCP-XXXX-1 subjects, or suspected to be one, are all asigned to a humanoid or animal containment chamber. Further information about their containment cell, needs, and permits, are designed in Addendum-XXXX-1. Each SCP-XXXX-2 subject is asigned to a different containment cell, speacialized for their needs, and adyacent to the SCP-XXXX-1 subjects' cell. Interaction between SCP-XXXX-1 and -2 subjects is allowed once in a week for no more than an hour.
Description: SCP-XXXX-A was discovered in the ████████ ocean, near the coast of █████████,█████ in ██/██/201█ after seven (7) months of research in the suspected area
