The 'giant Gippsland earthworm' (''Megascolides australis''), is one of
Australia's 1000 native
earthworm species. These giant
earthworms average at 80
cm long and 2 cm in
diameter but can reach 3
meters. They have a dark purple head and a pinkish-grey body.
They live in the
subsoil of blue, grey or red
clay soils along stream banks and some south or west facing hills of their remaining
habitat which is in
Gippsland in
Victoria, Australia.
These worms live in deep
burrow systems and require water in their environment to
respirate. These worms rarely leave their moist burrows. They have relatively long
lifespans for
invertebrates and can take 5 years to reach maturity. They
breed in the warmer months and produce large
egg cocoons which are laid in their burrows. When these worms hatch in 12 months they are already 20 cm long.
They can sometimes be heard in their habitat making gurgling sounds underground.
Threatened status
Like many of Australia’s native species,
European colonisation has caused their decline and they are now a
protected species.
