A huge, bizarre aquatic creature with a massive pitch-black body covered in thick scales. It has several pairs of sharp limbs, a heart-shaped armor on its head with six eyes glowing with eerie faint green light, and a body that coils like a centipede. It possesses two hook-like weapons near its mouth. It killed Karen and Chuck and attacked the small boat by ramming it from below. It is described as a long, dark, segmented figure.
