Crawler (Warhammer 40,000)

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

Description
Appearing somewhat similar to a cuttlefish, Crawlers have evolved a hard drill-like shell with which to burrow beneath the polar deserts of their homeworld, Luther Macintyre IX. They are not predatory creatures, feeding mainly on the microscopic life found in the subsoil of most planets, although they are large enough to be a threat to humans should they become cornered or enraged. In this event, Crawlers can use their powerful tentacles and sharp beaks to deadly effect.

Crawlers are the primary diet and preferred food of Ambulls.

History
After their discovery on the desert death-world of Luther Macintyre IX, Imperial spacefarers introduced Crawlers to many other planets, possibly as sustenance for the imported Ambulls which they sought to domesticate. Like the Ambulls, however, Crawlers proved impossible to contain, and so now more than a few Imperial worlds boast populations of wild Crawlers.
