Habits and Lifestyle


Diet and Nutrition

As the name implies, the common slug eater is a specialised predator and feeds on snails and slugs, mostly finding its prey through chemoreception, using its tongue. It swallows its prey quickly before too much defensive mucus is produced, extracting snails from their shells through the shell opening, or by smashing the shell against a rock while grasping the soft body in its jaws.

Mating Habits

The common slug eater usually gives birth to litters of three to twelve young. However, broods from large females may consist of as many as 22 newborns, each measuring eight to eleven cm (3⅛-4¼ inches). The total combined weight of the young may exceed the weight of the female after giving birth. Birthing season is January and February (late summer in southern Africa).
