Ocularan Worm

The Ocularan Worm, also called the Jedenoko (Jay-den-oh-co) in certain regions, is a massive worm that can tunnel through various earthen materials. They rarely attack unless otherwise provoked. How they can be provoked remains just as bizarre; anything from mild earthquakes to extreme noises can evoke the ire of this subterranean beast. Due to the nature of the creature, Ocularan Worms are only found in desert and tundra regions.

Appearance
The Ocularan Worm presents itself as a massive serpent-like creature that has an aptitude for burrowing complex tunnels. The creature's fanged mandibles appear to be evolutionary traits specifically inherited for digging through sand and dirt. The main body is composed of a vulnerable stomach and a chitin carapace running the length of the back. Depending on regional variant, the carapace and stomach will be white and blue or beige and brown for the tundra and desert regions, respectively. Likewise, the namesake feature of the Ocularan Worm is a single eye mounted upon the face; desert variants feature a brown eye, while frost variants feature a more sinister red eye.

Diet
Ocularan Worms are large creatures that are easily angered, but their feeding habits are similar to whale sharks. Special organs located down the esophagus allow Ocularan Worms to filter minerals and vital nutrients out of the sand, snow and dirt that it swallows, allowing to keep itself well-fed, even during combat. Once it has absorbed whatever it needs from these raw materials, it can then spit them back out in a deadly beam projectiles. Desert variants fire out high-impact sand blasts, while the deadlier frost variants fire out condensed ice particles capable of freezing whatever it hits.

Habitat
The Ocularan Worm only has two known habitats: tundras and deserts. Why it only chooses to roam these two biomes is unknown, though it is assumed by scholars that the ground is easier to tunnel through in both cases. Such would not be the case for tundras, as the ground would likely be frozen over; it is entirely possible that the Ocularan Worm can break through dirt and rock through the force of its immense weight alone. At first appearance, Ocularan Worms seem to be nomadic creatures as they are always seem roaming. This is not true; they are theorized to have nests far beneath the surface. No one has ever delved down deep enough to find out, however.
