 Item number SCP-924 Object Class Euclid Special Containment Procedures All specimens of SCP-924 are to be kept in separate 7m x 7m x 7m saltwater tanks within Site-46. The water is to be kept at a steady temperature of 1.6°C, or 35°F. All observation points are to be constructed of reinforced glass. If a tank must be entered for reasons of experimentation or cleaning, the water is to be heated to a temperature of 7°C, or 44.6°F. Entering tanks outside these conditions is prohibited. Each SCP-924 is to be supplied with 85kg of fresh meat on a monthly basis. The capture or elimination of wild specimens of SCP-924 is to be carried out by Special Task Force TAL-2, Polar Pathfinders. Description SCP-924 is a species of pale humanoid measuring approximately 2m, or 6.5' in height. The entities have the appearance of a waterlogged human corpse, with the addition of several bony antler-like growths on the head and a set of external gills located just below the ribcage. They are capable of swimming at speeds up to 30km an hour, and surviving at depths of up to 1km. SCP-924 requires a near-freezing Arctic environment to function properly, and will lapse into a state of estivation if the water around it rises above 4°C, or 39.2°F. SCP-924 is an ambush predator, attacking prey from underwater using either a hole in an ice as an appropriate ambush location, or by simply breaking through the ice itself. SCP-924 is highly sensitive to both smell and vibrations, allowing it to track prey from significant distances or through the ice. If the attack is successful, the target is promptly drowned by SCP-924. Following this, the body will be dragged down to the ocean floor by SCP-924 for consumption. SCP-924 will release drowned bodies after 1-6 hours. Recovered bodies show all signs of prolonged submersion and high pressure, as well as liquid faction and consumption of internal organs and muscles. Bodies will also contain high levels of virulent bacteria, which, when exposed to the human body, will break down most types of connective and muscle tissue while leaving skin and bones unharmed. Bodies will remain active within the body for up to two weeks after feeding. SCP-924 was first recorded as a series of mysterious disappearances of ice fishermen in the area around ████████, while the species requires a below-freezing environment to function properly. As its internal activity lessens as the temperature around it increases, it has been known to migrate south during the winter to find prey. The southernmost encounter with an SCP-924 was approximately three miles outside ██████ Michigan. Addendum. An incident on ████-2000 while resulting in no casualties proved that SCP-924 capable of supporting themselves and moving outside of water, and that attacks on unwary fish and vessels are possible. Global Task Force TAL-2 has revised their protocols accordingly.
