Lumbricus terrestris is a large, reddish worm species thought to be native to Western Europe, now widely distributed around the world (along with several other lumbricids). In some areas where it is an introduced species, some people consider it to be a significant pest for out-competing native worms. [1]

earthworm, any one of more than 1,800 species of terrestrial worms of the class Oligochaeta (phylum Annelida)—in particular, members of the genus Lumbricus. Seventeen native species and 13 introduced species (from Europe) occur in the eastern United States, L. terrestris being the most common.
EarthWorms (Lumbricus terrestris) Earth Worm Characteristics. Earthworms are made up of many small segments known as ‘annuli’. These annuli are ridged and covered in minute hairs that grip the soil allowing the worm to move as it contracts its muscles. At about a third of the worms length is a smooth band known as the clitellum.

The Night Crawler (Lumbricus terrestris) is a large worm, measuring up to 25 cm in length and up to 1 cm in diameter. They have a distinct, darker coloured "head" end which does contain the primitive "brain" of the animal, and this tends to be the end of the worm that travels "forward" the most.
Large earthworms, or night crawlers (Lumbricus terrestris), are cultivated and sold as bait for freshwater fishes and as humus builders in gardens. The sludge worm Tubifex , abundant near sewer outlets and thus an indicator of water pollution, is collected and sold as food for tropical fish.
Meet the earthworm (Lumbricus terrestris) including their appearance, diet, habitat, range, lifespan, facts, breeding and behavior.
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. It is about 90–300 mm long, and has around 110–160 segments.
Lumbricus terrestris is relatively large, pinkish to reddish-brown in colour, generally 110 - in length and about 7 – in diameter. It has around 120-170 segments, often 135-150. The body is cylindrical in the cross section, except for the broad, flattened posterior section.
