Spine Banks
From Warhammer 40k - Lexicanum
Spine Banks are a Tyranid Biomorph.
In 4th Edition they are rows of spines embedded in cavities in the carapace of the creature which are fired by muscle contraction at close ranges. This showers an area with spines covered with poison which easily incapacitate and distract nearby enemies.1-p33
