In Britain, it is primarily called the common earthworm or lob worm (though the name is also applied to a marine polychaete). In North America , the term nightcrawler (or vitalis ) is also used, and more specifically Canadian nightcrawler , referring to the fact that the large majority of these worms sold commercially (usually as fishing bait ...
The Lumbricidae are a family of earthworms.About 33 lumbricid species have become naturalized around the world, [1] but the bulk of the species are in the Holarctic region: from Canada (e.g. Bimastos lawrenceae on Vancouver Island) and the United States (e.g. Eisenoides carolinensis, Eisenoides lonnbergi and most Bimastos spp.) and throughout Eurasia to Japan (e.g. Eisenia japonica, E. koreana ...
A similar species, Millsonia anomala, was most active at 10–17% moisture content. The substratum for Lumbricus rubellus is related to the species food sources and pH and moisture requirements. Dung is the species preference. [ 2 ]
Oligochaetes are well-segmented worms and most have a spacious body cavity (coelom) used as a hydroskeleton.They range in length from less than 0.5 mm (0.02 in) up to 2 to 3 metres (6.6 to 9.8 ft) in the 'giant' species such as the giant Gippsland earthworm (Megascolides australis) and the Mekong worm (Amynthas mekongianus).
Probably the longest worm on confirmed records is Amynthas mekongianus that extends up to 3 m (10 ft) [10] in the mud along the banks of the 4,350 km (2,703 mi) Mekong River in Southeast Asia. From front to back, the basic shape of the earthworm is a cylindrical tube-in-a-tube, divided into a series of segments (called metameres ) that ...
They are also often the numerically dominant earthworm species in England, especially in neutral to base-rich grasslands and arable soils. [9] Because Allolobophora chlorotica is an endogeic worm, it builds complex lateral burrow systems through all layers of the upper mineral soil. This species of worm rarely comes to the surface, instead it ...
Eudrilus eugeniae, also called the "African nightcrawler", is an earthworm species native to tropical west Africa and now widespread in warm regions under vermicompost; it is an excellent source of protein and has great pharmaceutical potential. [1] [2]
Eisenia fetida, known under various common names such as manure worm, [2] redworm, brandling worm, panfish worm, trout worm, tiger worm, red wiggler worm, etc., is a species of earthworm adapted to decaying organic material. These worms thrive in rotting vegetation, compost, and manure. They are epigean, rarely found in soil.
