From Warhammer 40k - Lexicanum
Living in the darkened recesses and sump holes that abound in the Underhive of Necromunda, Milliasaurs are hideously mutated centipedes which can reach up to two metres in length.
Ambush predators, they will wait for unwary creatures to draw too close before speeding out and biting them with their poisonous fangs. Their venom will render all but the largest of creatures incapacitated within minutes, allowing the Milliasaur to drag the prey back into their lair to be consumed at great leisure.
