These slugs are believed to be mostly subterranean dwellers. Gut analysis of one species found both plant and animal matter, indicating that they are facultative predators who will also eat vegetation. They have been recorded as eating
pill millipedes of the genus
Sphaerotherium, snails, other arthropods and soft-bodied invertebrates such as earthworms. The prey is subdued by injecting a toxin into its flesh. ==References==
