An alien

I have been thinking about space aliens recently and I made these guys up. They can fold up into little defensive balls. Their eye is on a stalk and constantly flicks around to see in three dimensions, like we do by having two eyes. They are mentally connected in some way that leads to them having little sense of ego, and functioning like a massive cluster of ant-colonies. They are space-faring and have built enormous, haphazard space stations all around their home planet.
