 SCP-565 is an ambulatory human head, which appears to mimic the behavioral patterns of Carpillus convexus, a species of coral crab. Its chief method of ambulation is the manipulation of tendrils of unfurled brain matter. These tendrils are often utilized as legs, allowing SCP-565 to scuttle along the sea floor like a crab. But occasionally are operated for motion and manipulation in a manner similar to the tentacles of an octopus or jellyfish. To date, Foundation research has proven inconclusive on how and why SCP-565 remains animate or how it is able to manipulate neural tissue in a manner suggestive of musculature.
