The worm has a hydrostatic skeleton and moves by longitudinal and circular muscular contractions. Setae – tiny hair-like projections – provide leverage against the surrounding soil. Surface movements on moist, flat terrain were reported at a speed of 20 m/h and, based on measurements of the length of the trail, nocturnal activity away from ...
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 ...
The worms require loose soil to burrow in and soil moist enough for gas exchange. [3] Further requirements include such abiotic factors as pH and temperature. Various abiotic factors are significant to Lumbricus rubellus. pH is of particular importance; a range of 5.5 to 8.7 is acceptable with a preference for neutral soils. [4]
Lumbricus terrestris has several common names, including common earthworm, nightcrawler, and dew worm. It is strongly pigmented, brown-red dorsally, and yellowish ventrally. Setae are widely paired at both ends of the body.
Dendrodrilus rubidus is a species of earthworm in the family Lumbricidae.It is native to Europe, and it is a widespread introduced species, [1] occurring on every continent except Antarctica, as well as many islands. [2]
The Global Forum on Food Security and Nutrition suggests edible insects as a solution to the “rising costs of animal protein, food and feed insecurity, environmental pressures, population growth ...
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).
Almost all species of worms have the same method of reproduction. In the family of Lumbricidae, reproduction occurs by cross parthenogenesis reproduction. [8] Parthenogenesis reproduction is a type of asexual reproduction that was not require fertilization of the egg cell. [14]
