Miner's horror

this immense creature was first discovered 5,000 years before the Battle of Yavin by a group of pirates who stumbled upon a specimen. Their distress calls were almost ignored, and the only ship to respond found a holed wreck and a number of unusual creatures. The crew managed to kill one and return with it, and subsequent encounters have been quickly investigated. Measuring more than 20 meters in length when fully-grown, the miner's horror resembled a huge, segmented mollusk with several large spines sticking out from its back. Their heads are dominated by a single, immense eye, and their mouths are filled with saw-like teeth which can dig through solid rock. They exist in the hard vacuum of space, floating from asteroid to asteroid to obtain food. They grind up any rocks they locate into digestible pieces, and a single miner's horror has been documented to consume an entire asteroid field over the course of several decades. Despite their fearsome appearnce, they are slow-moving, and can be avoided.
