They were described to surface after heavy rain, were almost 4 feet long, 6 feet when stretched out, and were about as thick as ones forefinger[2]. [5][6], Gippsland earthworm colonies are small and isolated,[7] and the species' low reproductive rates and slow maturation make those small populations vulnerable. I.

These nutrients become concentrated in the worms digestive system and released back into the soil in the excreted earthworms cast. The many interesting species (including one with bioluminescence) of native earthworms are affected by some of the more aggressive species which are primarily the successful colonizing invasive species. WebThe biggest worm ever found is the African giant earthworm (Microchaetus rappi), which can grow up to 6.7 meters (22 feet) in length and 2 centimeters (0.79 inches) in diameter.
