The rotik is the most numerous of the leviathans that haunt the waters of Amtor. It may attain a length of fully a thousand feet, It has a wide mouth and huge protruding eyes between which is a smaller eye perched on a cylindrical shaft some fifteen feet above its head. The shaft is erectile, and when the creature is at rest upon the surface or when it is swimming normally beneath, it reclines along its back. But when alarmed or searching for food, the shaft springs erect. It also functions as a periscope as the beast swims a few feet beneath the surface.
