Description

Slug and snails belong to the class Gastropoda. The family Athoracophoridae groups together the leaf-veined slugs. This relates to the pattern they have on their bodies. This slug is the largest Australian native slug found on the east coast. They can vary in colour; white, off-white, yellow, dark or light grey, beige, pink, red, or olive green. Whatever colour, they all have a triangular mark on the top of their bodies which can be orange, dark red or purple-red. Juveniles don’t have the triangle marking. Within the triangle is their breathing hole. This slug is able to secrete a sticky mucus (separate from the slime they move along) which is able to effectively glue any predators to a surface if they approach it.

Adult size: 14 cm

Why they are Neutral
They feed on microscopic algae (lichen) growing on eucalyptus trees and rocks. As with the lichen moth, they are a good indicator of a healthy environment. Lichens are extremely susceptible to atmospheric pollutants. If there are creatures feeding on the lichens then there must be a healthy population of lichens to provide this food source.
