Bio-cannon
From Warhammer 40k - Lexicanum
The Bio-Cannon is a Tyranid Biomorph coming in various sizes and functions.[1][3]
Equipped on titan-sized creatures such as the Hierophant and Harridan, the Bio-Cannon is triggered by a massive electro-chemical shock that spews forth a hail of highly venomous and corrosive maggot organisms. These organisms then impact on the target, splattering a rain of bio-acid and poison that can melt through nearly any material in a matter of seconds and reduce the unfortunate victim to a steaming pile of bubbling goo.[1]
Larger versions of Bio-Cannons are sometimes found on Tyranid Bio-Ships.[3]
