SCP-745 is a bipedal nocturnal predator. The head is a bloated sack of clear skin that lacks visible sensory organs or a skull. The brain of the creature can be directly observed and is wrapped in a web of bio-luminescent organs below the skin. Skin covering the rest of the body has a deep black coloration. Living specimens of SCP-745 are capable of producing a steady output of 1400 to 3200 lumens from their head. At night, this effectively obscures the rest of the body, causing it to glow.
