One of the few instances of native fauna in the Under-Empire, the cave viper is an eyeless pale white snake that consumes normal rats and lairs near geothermal vents for warmth. It is sensitive to vibrations and heat, allowing it to strike in complete darkness as if it were sighted, and is quite territorial, injecting its venom into any large creatures that come near it.[1a]

Cave vipers seldom grow longer than 4 feet in length, though there are reports of rare specimens reaching nearly 7 yards in length. These gigantic vipers cause a great amount of apprehension in Skaven, who exhibit an almost instinctual fear of the serpents.[1a]
