The Giant Gippsland earthworm averages 3 feet in length, but has been seen as long as 9 feet. It is native to the clay soil along streams in Victoria, Australia. The worms take 5 years to mature and live for about 10, surprisingly long for invertebrates. Unlike other types of worm, the Giant Gippsland rarely, if ever, comes to the surface, but its location can be detected by the audible gurgling that their bodies make as they slither through their labyrinthine burrows.
