Lumbricus Terrestris is relatively large,generally 110 to 200 mm (4.3 to 7.9 inches) and about 7 to 10 mm (0.28-0, 39 inches). It has about 12017 segments, often 135150. The body is cylindrical with the body, except for the rear and flattened back. Deep brown next to reddish brown and the back declining to his back.
The worm has a hydrostatic backbone and travels through longitudinal and circular muscle contraction. SETAE-Correspond to the surrounding ground-like protrusions like small hair. Surface movements on moist, flat terrain have been reported at velocities of 20 m / h, with nocturnal activity outside burrows during a single surface advance of up to 19 m, based on path length measurements. It is estimated. Such movements are apparent during and after heavy rains and usually occur when people notice a relatively large number of earthworms, for example in urban ecosystems. This form of activity is often seen as a way to escape floods and soaked caves. However, L. This is not the case because terrestris, like other earthworms, live in oxygen-rich water for long periods of time and can last for weeks. Worms often move on the surface in less harsh environmental conditions where the temperature and humidity are sufficient. This can be caused by the availability of resources or the desire to avoid mating with close relatives.
What does Lumbricus terrestris mean?
The scientific name Lumbricus terrestris comes from the Latin root. The word “Lumbricus” ordinarily means worm, while “terrestris” means “land”, “land” or “earth”, leading to its most common name, earthworm
Common name of Lumbricus terrestris
L. terrestris is referred to by a variety of other common names. In the United Kingdom, it is commonly referred to as the common earthworm or lob worm (though the name is also applied to a marine polychaete). The term nightcrawler (or vitalis) is also used in North America to refer to this species.
There are several names for this creature in Canada, including “dew worm” and “Granddaddy Earthworm.” It is referred to as “rain worm” in a number of Germanic languages, such as Gemeiner Regenwurm (“common rain worm”) in German and Stor regnorm (“rain worm”) in Danish, for example (“large rain worm”). Throughout the rest of the world, many references are made solely to the scientific name, with only sporadic mentions of the above-mentioned names.
Classification of Earthworms
There are three main types of earthworms
1. Anecic earthworms
Anesthetized earthworms make permanent vertical holes in the soil. They eat the leaves on the ground and pull them into the burrows. They are also cast on the surface and these castings are found quite often in grasslands. Some poor earthworm species also create shell mounds (mountains of excrement) around the entrance to the burrow. Anesthetized species are the largest earthworm species in the United Kingdom. The edges of the head are dark (red or brown) and the tail is light.
2. Endogeic earthworms
Endogenous earthworms inhabit and feed on the soil. They move through horizontal holes in the ground, feed them, and reuse those holes to some extent. Endogenous earthworms are often pale, gray, pale pink, green, or blue..
3. Epigeic earthworms
Epigerium mizu inhabits the surface litter. These species tend to live and feed on litter, rather than nesting. Also, epidermal earthworms are often bright red or maroon, but not striped. Epidian earthworm species include Dendrobaena Octaedra, Dendrobaena attemsi, Dendrodrilus rubidus, Eiseniella tetraedra, Heliodrilus oculatus, Lumbricus rubellus, Lumbricus castaneus, Lumbricus festivus, Lumbricus friendi, Satchellius Mammals.
Conclusion
Lumbricus Terrestris is a relatively large, rosy pink, typically 110-200 mm (4. 3-7. 9 inches) and approximately 7-10 mm (0. 280. 39 inches). The worm has a hydrostatic backbone and is driven by longitudinal and circular muscle contractions. There is activity. Such movements occur during and after heavy rains, usually when a relatively large number of earthworms are noticed, such as in urban ecosystems. Because, like other earthworms Worms often move over the surface under less harsh environmental conditions where temperature and humidity are appropriate.
