The habitat the worms used to live in was tall eucalypt forests. Most of this has been cleared for farming, but the worms have continued to survive because they live deep underground. They have been listed a vulnerable species because of these changes. The worms only lay a single egg, between 4-7cm in size. These can take up to one year to hatch, and the worms take several years to become adults, and be able to reproduce. This slow rate of growth, also makes them a vulnerable species.
