Arachnis brood-keepers were creatures that were assimilated into the Zerg Swarm, becoming queens.[1] They possessed an egg-laying ovipositor[2] capable of laying medium-to-large clutches of eggs every season. This ability was revised and altered for post-Brood War queens.[3]


The name "arachnis" is possibly derived from the taxonomic class Arachnida, which includes spiders, scorpions, and related species.
