Megnad

Description
A megnad is a alien lifeform that can be found on the surface and inside hollow areas of asteroids. They have sucker mouths that take up the entire underside of their bodies and they use these mouths to suck resources out of the asteroid, which they then garner nutritional value from. Asteroid miners often find them extremely annoying, as the asteroids infested with megnads often have little resources to yield for the miner, as the megnads have consumed it all.
