Where do earthworms usually live?
Earthworms and their relatives live anywhere there is moist soil and dead plant material. Earthworms are most abundant in rainy forest areas, but can be found in many habitats on land and in freshwater. All earthworm species need moist soil conditions to survive.
Where do earthworms originate?
Origins. Most of the invasive earthworms are European or Asian and came over in soil during the eighteenth century as Europeans began settling the North American continent. The worms were originally transferred through the horticultural trade, probably in the soil bulbs of European plants being carried to the Americas.
Are earthworms indigenous to the United States?
No. Earthworms are native to the United States, says Melissa McCormick, ecologist at the Smithsonian Environmental Research Center, but the earthworms in some northern parts of the country (including Vermont) aren’t indigenous.
Did Europeans bring earthworms to America?
New earthworms began entering North America as early as the 1600s, with the first European settlers. They crossed over in root balls or the dry ballast of ships. As the British, French, Spanish and Dutch colonized the American continent, they were largely oblivious to another colonization going on under their feet.

Do lobsters poop out of their mouths?
Food is handled and processed first by the mouthparts and then is crushed by the mandibles before being swallowed. It then makes its way through the three main regions of the digestive system. Any remaining material (not digested) is packaged into fecal pellets surrounding by a mucous membrane.
