Simply referred to as Arachnids, this species has never been studied or categorized, as their existence is, for most of the galaxy, the stuff of rumour and legend. No one has seen an arachnid since the Ronins eradicated the last pockets of them during the final days of the Daybreak War.
Very little is known about these creatures, besides the fact that they can survive in space and they hunt in packs or swarms. It is said that they originally hatched out on an asteroid belt in the Aluxi system, attacking the Guardian homeworld.
While it is assumed that they could no longer pose a threat to another race as a whole, it remains likely that if arachnid eggs should ever be hatched and unleashed upon a planet or moon they would cause severe destruction.
