 The curation and manipulation of living organisms through anomalous means represents the most immediate threat posed by sarcasm. Footnote 43 DNA analysis suggests that some sarkin organisms have been created through a process of artificial selection, breeding organisms including humans to the point where they no longer resemble their ancestors. Enough patterns have been discovered among these organisms that they can be divided into different species. These organisms display no sign of fear or pain and regenerate entries at an anomalous rate. Below is a partial list of such entities. SK Biotype A Colocally referred to as behemoths by personnel, these entities are commonly over 4 meters tall, weighing approximately 7,000 kilograms with pale, flabby skin, lacking visible eyes, ears, and noses. Their faces dominated by a large toothy mouth. The first recorded instance of an SK Biotype A was SCP-2480-2. They appear to be of limited intelligence. SK Biotype B Generally 1.5 to 2 meters tall weighing approximately 250 kilograms, mouths are vertical, running the length of what approximates a face, spindly fingers in and 50 to 60 centimeter talons, bodies are partially protected by white, chitinous carapace. The flesh beneath dark red and visible and movable joints. SK Biotype Delta Also classified as SCP-2191-1, SK Biotype Delta are considered genetically human but have undergone several significant seemingly fatal mutations. SK Biotype Delta lack all major internal organs with the exception of the lungs, heart, and brainstem. The outer epidermis lacks pigmentation and displays a condition resembling cracked porcelain, possibly related to Harlequin syndrome. Entities appear androgynous, lacking or having somehow removed secondary sex characteristics. The regressed eyes are covered by a layer of skin, rendering them mostly blind but still able to react to light, universally displaying a version of wavelengths greater than 100 nanometers. Other deviations from baseline Homo sapiens include especially flat, upturned noses and funnel-shaped ears, both considered related to their dependency on olfactory and auditory perception. They do not appear to communicate via language, the only sound produced being a persistent clicking of the tongue, speculated to be a form of echolocation. SK Biotype Delta Colocally referred to as Snatchers by Personnel, prehensile organic structures dark red in color and with a tentaculoid shape. SK Biotype Delta are sedentary and are generally used by Sarkites to guard specific locations. SK Biotype E Known to Sarkites as a Karak, instances of SK Biotype E are organic, biologically living structures used as temples. The Foundation presently has a deceased instance, SCP-2095 in containment, but other possibly living instances are theorized to exist across the world. Update, living instances have been recently encountered by field agents, further information is pending. The creation of a Karak is more terrible than initially hypothesized, a living human is anointed, then repeatedly fed and shaped, its brain slowly atrophying as it becomes a living temple. The Sarkites cultivate flesh and bone as one might tend to bonsai tree. Dr. Tsukino SK Biotype Z Known to Sarkites as an Acolyth and his sacred white worm, instances of SK Biotype Z are symbiotic organisms found in the bodies of both Sarkites and Sarkite organisms. It is believed that they act as a secondary immune system, protecting the host against disease as well as greatly increasing their regenerative abilities. SK Biotype Z is also believed to be connected to the physical transformations some Sarkites undergo. SK Biotype H SK Biotype H may exist as or be composed of multiple species and generally refers to any SK Biotype that lacks a stable physical form, although this can occur in many if not all Sarkite organisms is critically injured. Existing as a gelatinous mass, such organisms were able to increase their size with no known limit by absorbing the biomass of those it encounters. An individual can be converted to an SK Biotype H by ritual, as it encountered when SCP-2075 caused the transfiguration and subsequent death to Dr. Albert Kronenberg.
