Every segment of the Larva’s body contains all the required organs to ensure its survival in the direst situations. Such a trait, combined with near-instant wound clotting, allows Larvae to function and morph normally even if cut in half.
The need to survive has played a key role in the evolution of the Larva’s carapace. Its plates have turned into an incredibly dense material that is not easily scratched—much less punctured—even by non-conventional weaponry
. We suspect this highly-resistant carapace served as a template for the enhancements to the heavily armored Ultralisk.
Larvae in young colonies only have access to a fraction of the DNA strains available to fully developed hives. As the cluster cycle progresses, living Larvae absorb new genetic data, while the freshly-spawned ones already have the additional blocks of the Swarm’s genome hard-coded in their DNA.
The inner layer of the creature’s skin is populated with receptor cells. Once an Overlord issues the morph command, the Larva’s organs are ejected—forming a hard egg-like cocoon—and its tissues are instantly reconfigured into the desired strain through a brief pupation period.
