An Biovore in battle

The Tyranid bioform called the Biovore (Tyranicus patris-boletus) is a powerful "living artillery" weapon for the Tyranid swarms. Deep within its squat, lumpen form the Biovore nurtures a clutch of Spore Mines -- living bombs that blanket the enemy in acids, poisons and pieces of chitin. A Biovore launches these mines from a dorsal aperture by means of a powerful muscle spasm. Even if the shot misses its target, the danger is far from over, for the Spore Mines are possessed of a rudimentary intelligence and detonate not on impact, but when they sense the proximity of a non-Tyranid lifeform. Fortunately, the Biovore's relative rarity amongst the Tyranid swarms is taken as a sign that the Hive Mind prefers to win its battles in bloody melee, but the truth is subtly different.

Over time, as the Hive Fleets pressed ever deeper into the galaxy, their victories were much harder won as their enemies began to concentrate on destroying the swarm from great distance. In response, the pragmatic Hive Mind recognised the need for a bioform that could neutralise the enemy's long-range weaponry, thus leading to the birth of the Biovore. Imperial savants believe that the Hive Mind may have made use of Orkoid genetic material to create the Biovore. Thus this creature is not merely a powerful weapon in the Hive Mind's arsenal, it is living proof of the adaptive nature of the Tyranid menace.
