Ambull

Ambulls are creatures which appear in Games Workshop's Warhammer 40,000 universe.

Description
Twice the height of a human, Ambulls are a race of subterranean animals which are indigenous to the death world of Luther Macintyre IX. Ambulls have a hard, chitinous carapace and a semi-simian stance, with arms which reach to the ground even when standing upright. Their claws are diamond-hard and used for tunnelling through the soft bedrock of their homeworld, and they possess a pair of razor-sharp mandibles with which to consume their prey, dangerous cuttlefish-like creatures called Crawlers. Ambulls are also highly resistant to extremes of temperature.

History
After their discovery on the desert world of Luther Macintyre IX, Imperial spacefarers introduced Ambulls to a plethora of other worlds with the intent of domesticating them and making use of their considerable biological talents. However, due to their unique burrowing abilities, the creatures are notoriously hard to keep in captivity, and so hundreds of Imperial worlds now boast thriving populations of wild Ambulls.
