Rippers

Rippers (Minoris omniphagea) are a small, maggot-like species of Tyranids that serve as the primary means of devouring bio-mass from a planet for a Tyranid hive fleet.

Rippers are the most numerous of the Tyranid creatures, and in great swarms they can pull down and consume creatures many times their own size. However, they are completely mindless and will perish if they lose a synaptic link with the Hive Mind, although while under its guidance they are utterly relentless and pose a truly horrifying threat.
