Toxic Miasma
From Warhammer 40k - Lexicanum
Toxic Miasma is a Tyranid biomorph consisting of vents sprouting from the backs of some Tyranid creatures to release toxic gases of microscopic algal formations into a prey world's atmosphere, most notably the Venomthrope species. Even brief exposure to the miasma gases can cause a victim to choke to death on its own blood.[1][2]
