Gestation Sac
From Warhammer 40k - Lexicanum
The Gestation Sac is a unique Tyranid Biomorph.[1]
Embedded within this organism's body is a pulsating sac of membranous flesh and nutrient bio-slurry. As the battle rages, the graft swells and bulges as they grow at an exponential rate. Eventually an entire brood of Rippers will spill forth to squirm their way into battle.[1]
