Dune Scraper

Colossal Sand Worms that are found in the Parched Lands.
There is not much information about these behemoths. They roam beneath the deserts of The Parched Lands. Eventually, a Dune Scraper will burrow out of the ground and travel through the desert. It is still unknown as to where they are going or why they suddenly decide to surface.
Dune Scrapers have an incredibly strong shell that is virtually impenetrable. The only known way to successfully get through the shell is with another piece of shell.  Pieces of shell can be found around the desert, but it is incredibly rare to find intact. Once a Dune Scraper dies, the shell becomes very soft shortly after unless it is heated at 1700 degrees Celsius. 
Before a Dune Scraper surfaces, large waves or "Ripples" in the sand can be spotted. The time between the Ripples being sighted and the Dune Scraper surfacing varies. The shortest duration being 5 minutes and the longest duration being 2 hours.

Basic Information

Anatomy

Dune Scrapers have an incredibly strong shell that is virtually impenetrable. The only known way to successfully get through the shell is with another piece of shell.
Pieces of shell can be found around the desert, but it is incredibly rare to find intact. Once a Dune Scraper dies, the shell becomes very soft shortly after unless it is heated at 1700 degrees Celsius.
An average Dune Scraper is roughly 50 ft in diameter and 2000ft in length.
Every Dune Scraper has a hydration sac just behind its cranial bump that is well protected. Each hydration sac is roughly 5ft in diameter and can contain up to 2000 small hydration pellets. When a pellet is consumed, it can hydrate the average human for one day without them needing any additional water.

Genetics and Reproduction

It is unclear if or how Dune Scrapers reproduce. Many believe them to reproduce via Parthenogenesis.

Growth Rate & Stages

Unknown

Ecology and Habitats

Dune Scrapers are native to The Parched Lands and generally tend to appear closer to the center of the desert.

Dietary Needs and Habits

It is unclear what a Dune Scraper's diet consists of. It is known for them to eat anything that will give them energy. This includes people, insects, or even various rocky plants.

Perception and Sensory Capabilities

It is unclear if Dune Scrapers have eyes and it a topic of wide debate. They do seem to have a form of tremor sense which allows them to sense movement in their surroundings.
