[7] The Gippsland earthworm requires moist loamy soil to thrive; dense tree planting negatively affects soil humidity, which in turn negatively affects the species' habitat. It is thought that this is to ward off predators.This worm is also commonly known as the Tiger worm, or Trout worm, and it is native to Europe though has been introduced to every continent on the globe with the exception of Antarctica.

From this, the ensuing debates in the scientific literature focused on the questions of names, species, and genus. They break down decaying and dead organic matter so that it can be converted into rich soil. The worm also has a low reproduction rate and slow growth, which is further hindering its ability to grow its population. Have some feedback for us?

Microchaeta Rappi, Beddard (Lumbricus microchetus, Rapp), p.269, [20] Benham, Studies on Earthworms, Part II. This worm has very limited distribution and has not been found outside of its native state. microchaetus. They are darker at one end, with a red-brown pigmentation. In total, New Zealand has at least 171 species of native earthworms and 23 non-native species. If they dont though, they will suffocate and die. EX. Additionally, they dont have eyes, so they use receptors within their skin to sense touch and light. This is why earthworms surface after heavy rains, even though it is extremely hazardous for them to do so. EX. The African Nightcrawler has a uniform purple-grey sheen. To compensate for this hazardous existence and the need for a lot of them to cultivate the earth, they reproduce very quickly, with a freshly hatched worm being ready to breed within about 6-9 weeks of coming out of its cocoon. These are: Microchaetus, Geogeina, Kazimierzus, Tritogenia, Michalakus, and Proandricus[12]. What makes this more incredible is that a typical garden variety of earthworm can process about 10 pounds of organic material per worm per year. According to research done at the Rothamsted Experimental Station, depending on soil quality, there can be anywhere from 250,000-1.75 million earthworms per acre of land.

They have some pigmentation but are often a milky color, especially native worms, as they predominantly reside underground. [5][6], Gippsland earthworm colonies are small and isolated,[7] and the species' low reproductive rates and slow maturation make those small populations vulnerable. These almost never surface. [3][4] They have a dark purple head and a blue-grey body, and about 300 to 400 body segments.[2].
