Millistoma are a very rare and very large species of carnivore native to Saturn. They are the only animals known to prey on or otherwise threaten rukhs, and thus serve as a feared mythological figure in rukh tradition.

Etymology Edit

Millistoma literally means "thousand mouths." The humans who first learned of the creatures gave them the binomen Millistoma mythicus to indicate their presumed mythological status, but changed this name to Millistoma gigas, referring to their titanic size, upon learning they were real.

Description Edit

Anatomy & Physiology Edit

Millistoma are the largest organisms to inhabit Saturn and the largest in the Solar System. Their exact size is never detailed, but the individual that appeared at the end of Saturn Rukh was the size of "a small [U.S.] state," indicating a width somewhere in the area of 160 kilometers (100 miles). Millistoma consist of thousands of smaller components, each with a large, toothy mouth, all arranged in an amorphous mass. A millistoma's body can shape itself into a gigantic "bowl" in order to catch prey, or into "hills" and "valleys" when more precision is required.

Diet Edit

Millistoma spend most of their lives feeding on the decaying remains of other Saturnian life forms that fall into the atmosphere's depths. However, during the summer, they rise into the warm equatorial regions in order to feed on living prey. They seem to prefer hunting rukhs, devouring entire flocks at once.

Environment Edit

Millistoma inhabit a different region of Saturn than its other inhabitants. They dwell deep below the ten-bar water cloud layer, in a much hotter layer of the atmosphere that likely lies close to where it transitions to liquid hydrogen. They spend most of their lives here, feeding off dead animals that fall to these depths.
