Meet these giants can only be in the hills of Southwestern Gipslenda in Australia. They are long-lived, their life expectancy can reach 10 years old! If only they had not become a tasty bait on the hook.

Spring and summer are the main periods for reproduction. These worms - hermaphrodites, which means that adults have both male and female reproductive system. But for fertilization still need a couple. And each of them and then lays her eggs in a special cocoon, which he himself had created.

They live in a two-meter-long burrows, which themselves had dug. Residents are picky. The basic requirement for living conditions - high humidity of the soil. During movement through the tunnels, they can reach high speeds. As a result, formed a specific gurgling sound. And it all is that the worm burrows inside covered with a special viscous secretion, which makes the walls more smooth. This in turn improves the speed of movement and the emergence of such a sound. 

Australian giant earthworms are protected by the state. In their honor, even organized an annual festival - a "pocket" (the so-called aborigines of the worm).
