Some species of hammerhead worms produce a type of neurotoxin called tetrofotoxin to hunt creatures such as earthworms. They will paralyze a worm with the neurotoxin (found in the mucus secreted ...
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 ...
According to the FAO, edible insects require less feed than conventional livestock. For instance, crickets need six times less feed than cows and only half as much as pigs and broiler chickens to ...
The average thickness of the drilosphere (lining of an earthworm burrow) is 2 mm, [4] but it can be much wider (about 8 mm) around the burrows of litter-feeding earthworms. [ 5 ] Through the drilosphere, earthworms influence soil microbial communities, with effects on microbial processes related to soil organic matter and nutrient dynamics. [ 6 ]
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.
Perionyx excavatus is a commercially produced earthworm. Popular names for this species include composting worms, blues, or Indian blues. This species is marketed for its ability to create fine worm castings quickly. It has recently become more popular in North America for composting purposes. This species belongs to the genus Perionyx.
However, 'earthworm' can be a source of confusion since, in most of the world, other species are more typical. For example, through much of the unirrigated temperate areas of the world, the "common earthworm" is actually Aporrectodea (=Allolobophora) trapezoides, which in those areas is a similar size and dark colour to L. terrestris.
The European nightcrawler (Dendrobaena hortensis) is a medium-small earthworm averaging about 1.5 g when fully grown. Generally blueish, pink-grey in color with a banded or striped appearance, the tips of their tails are often cream or pale yellow. When the species has not been feeding, it is pale pink.
