Griff's Glowroids

Glow Moss, they call it. Little is known about it, other than it's an organic lifeform perfectly adapted to living in vacuum. It feeds on asteroids, and once it gets a hold, it's nigh-on impossible to eradicate, hence its other name – Hermit's Bane. As an alien lifeform, some say it should be protected – but try telling that to a rock hermit. Undeniably attractive to the eye, whatever it uses to break down the rock it feeds on is highly corrosive, which makes studying it difficult, if not impossible. There are tales told of it eating its way through hull plating and windscreens, and it seems particularly attracted to copper. But that's only old spacers' talk, which exobiologists dismiss as fanciful.
