Duracrete slugs were a species of non-sentient creatures that fed off duracrete, a sturdy material used to make buildings. Once digested, the duracrete then oozed from the slug's body, thus forming its armored skin. The largest specimens had a length of 10 meters. Their tentacles allowed them to sense their surroundings.
