Creature:Ravageworm

Ravageworms are surprisingly sapient and horribly malicious. They hunt in swarms of millions, aiming to consume anything organic that they can digest. As polyopsids, they are built to be able to detect prey from any angle through the use of many eyes, although they also sport two pairs of antennae to aid in their voracious search for sustenance. Several civilizations have been wiped from the face of the universe by an invading swarm of Ravageworms, and some species have resorted to simply blowing apart planets they have been discovered to possess an infestation of these pests, as many races have grown pessimistic that a Ravageworm swarm attack can even be effectively halted; by destroying the worlds they are attacking, they can "save" the inhabitants of the planet the pain and suffering of being torn apart while still alive.

Technology
Ravageworms, being sapient, are not without technology, although it is in a form many species are not accustomed to seeing. Ravageworms build their starships out of the dead and dying bodies of their own kind, and should a Ravageworm survive to the end of its lifespan or they consume a world in its entirety, they will usually be converted into one of the Ravageworm's Infestor Ships. These ships are made up of billions of their own bodies to create the hull, which have been covered in a cementing material excreted by Ravageworms and made out of various materials that make up the ground upon which they are currently inhabiting; this is to prevent atmosphere from escaping. Any and all living Ravageworms converted into the vessel are then overtaken by a contagion that they all carry within; this mutates their form to allow them to combine with others in a transmogrification procedure, turning them effectively into large cells and transforming the corpse-ship into a "living" organism all to itself. Generations of Ravageworms will then allow their contagions to transform them into cells to use as large wings to help the Infestor Ships in leaving the atmosphere; oftentimes they will remove as much atmosphere from the planet for the Ravageworms to breathe and to make the pressure on their vessels lessened, thereby allowing them an easier time leaving the planet's gravity well.
