Australia has a huge of diversity of worms on land, sand and sea such as the giant Gippsland earthworm which can stretch up to 3 metres

One of the world’s largest worms might escape notice, if not for the loud gurgling noises that can be heard coming from underground as the species burrows and squelches through its moist clay.

The giant Gippsland earthworm, a purple and pink colossus that lives in a small, wet patch about 100km east of Melbourne in south-east Australia, reportedly stretches as long as 2 to 3 metres.
