 SCP-327 is a female specimen of a mammalian species, resembling members of the order Serenia. The subject bears anomalous bodily features. The flippers bear distinct fingers, and a functioning opposable thumb, and the skull and facial features resemble that of a human. SCP-327 was hit by a boat propeller five to ten years before retrieval, as evidenced by heavy scarring on the head and back. SCP-327's anomalous effect is based around its primary vocalization, taking the form of songs. These vocalizations are regarded as highly unpleasant to listen to, and will result in severe headaches and audiovisual hallucinations in humans, persisting for six to twelve hours.
