The latter stages of a Tyranid invasion, being the "consumption" and "assimilation" stages, is marked by enormous capillary towers and bio-ships deploying their feeding tubes. This typically marks the death of a world where the only recourse is [[exterminatus]]. However, it's also typically when bio-ships and [[hive ship]]s are most vulnerable, having likely expended a significant amount of biomass in their initial assault. Destroying or damaging the Tyranid Hive Fleet (via exterminatus or other means) while it is feeding can potentially deny the hive fleet biomass to fuel to renew its assault. Destroying the towers, or feeding tubes, or sometimes even the bioships themselves, before the biomass reaches a bioship will would deny the fleet valuable biomass to assimilate. Thus leaving the hive fleet as a whole, in a weaker state.{{Fn|2c}} This stage also provides an opportunity to destroy a synapse node creature aboard a bioship, whether by destroying the ship or via a Kill Team boarding the vessel to assassinate the link.{{Fn|2d}} This would then lead to the Tyranid bioforms being thrown into disarray, becoming little more than beasts without the Hive Mind guiding the assault.{{Fn|5}}
