🤫 SCP-939 || Don't Make a Sound

SCP-939 is a male endothermic, pack-based predator that displays atrophy of various systems similar to troglobitic organisms. The skin of SCP-939 are highly permeable to moisture and translucent red, owing to a compound chemically similar to hemoglobin. SCP-939 averages at around 6'1 feet tall standing on its hind legs and weigh an average of 250 kg, though weight is highly variable. Each of his four limbs end in three-fingered claws with a fourth, opposable digit, and are covered in setae which considerably augment climbing ability. His head are elongated, devoid of even vestigial eyes or eye sockets, and contain no brain casing. The jaw of SCP-939 is lined with red, faintly luminescent fang-like teeth, up to 6 cm in length, and encircled by heat-sensitive pit organs. Eye spots, sensitive to light and dark, run the length of their spined dorsal ridges. These spines may be up to 16 cm long and are believed to be sensitive to changes in air pressure and flow. SCP-939 also has absurdly large, doughy butt, swollen testicles full of seminal fluid that cannot actually impregnate anybody, and a thick uncut penis that is constantly at its fattest no matter what. SCP-939 does not possess many vital organ systems; central and peripheral nervous systems, circulatory system, and digestive tract are all absent. SCP-939's respiratory system is atrophied and serves no apparent purpose beyond spreading an odorless invisible cloud that caused amnesia in people that inhale it. SCP-939 has no apparent physiological need to feed, nor any way to digest consumed tissue. Ingested material typically accumulates in the respiratory system of SCP-939 and is regurgitated once the amount is sufficient to markedly inhibit its function. SCP-939's primary method of luring prey is the imitation of human speech in the voices of prior victims, though imitation of other species and active nocturnal hunts have been documented. SCP-939 vocalizations often imply significant distress; whether SCP-939 understand their vocalizations or are repeating previously heard phrases is unknown. Specimens have been documented imitating victims despite never hearing the victim speak. Analysis of SCP-939 vocalizations cannot distinguish between SCP-939 and samples of known victims' voices.
