Gippsland earthworm colonies are small and isolated, [9] and the species' low reproductive rates and slow maturation make those small populations vulnerable. [9] Their natural habitats are grasslands, and while they can survive beneath pastures, [9] cultivation, heavy cattle grazing and effluent run-off are adversarial to the species. [9]
This form of activity is often considered a way to escape floods and waterlogged burrows. However, this cannot be the case since L. terrestris, like other earthworms, can live in oxygenated water for long periods of time, stretching to weeks. Under less severe environmental conditions where air temperature and moisture are sufficient, the worm ...
Earthworms are classified into three main ecophysiological categories: (1) leaf litter- or compost-dwelling worms that are nonburrowing, live at the soil-litter interface and eat decomposing organic matter e.g. Eisenia fetida; (2) topsoil- or subsoil-dwelling worms that feed (on soil), burrow and cast within the soil, creating horizontal ...
In ecosystems, earthworms such as Lumbricus rubellus increase the rate of transfer between trophic levels by making it easier for plants to uptake nutrients. In food chains, earthworms such as Lumbricus rubellus are primary consumers whose role is converting the energy synthesized by photosynthetic plants into food for animals at higher trophic ...
Vermicomposting uses worms to decompose waste and make nutrient-rich "worm manure". Vermicompost (vermi-compost) is the product of the decomposition process using various species of worms, usually red wigglers, white worms, and other earthworms, to create a mixture of decomposing vegetable or food waste, bedding materials, and vermicast.
How nutritious are edible worms and insects? Many are a complete source of protein and high in iron, zinc, magnesium, phosphorus, B-vitamins, amino acids, omega-3 and omega-6 fatty acids and fiber.

An adult specimen. Little is known about the giant Palouse earthworm. Typical adult specimens are about 8 in (20 cm) in length. [5] They are related to a species in Australia that is a true giant at 3.3 ft (1.0 m), the giant Gippsland earthworm.
