Glossoscolecidae
The Glossoscolecidae are a large family of earthworms (annelids) which has native representatives in South and Central America. The species '' Pontoscolex corethrurus'' has a circumtropical distribution. They are found mostly in forest, but one species of earthworms lives primarily in coastal beach sand. The earthworms in this family can reach up to 2 m in length.

Pontoscolex
''Pontoscolex'' is a genus of earthworms in the family Glossoscolecidae, or alternatively, in the family Rhinodrilidae. General characteristics The type species ''Pontoscolex corethrurus'' has a circumtropical distribution, although it originates in the Neotropics, probably in the Guiana Shield, Guiana Plateau. It reproduces Parthenogenesis, parthenogenetically, and under experimental conditions can complete its life cycle in about one year. Adults measure in length. Diagnostic characteristics There are eight setae per segment, arranged in regular rows, at least in the anterior part of the animal, whereas in the posterior part the arrangement varies (regular, more or less irregular, or in quincunx). No pigment is usually present. Male pores and tubercula pubertatis are in the Clitellum, clitellar region. The gizzard is in the segment VI. Three pairs of calciferous glands of tubular-dichotomous (panicled) structure are in the segments VII–IX. Earthworm#Form and function, Dorsa ...

Pontoscolex Corethrurus
''Pontoscolex corethrurus'' is an earthworm in the genus ''Pontoscolex''. It has a circumtropical distribution, although it originates in the Neotropics, probably in the Guiana Plateau. Description The worms are unpigmented and have around 200 segments. Adults measure in length. Reproduction It reproduces both parthenogenetically and (rarely) sexually, and under experimental conditions can complete its life cycle in about one year. Ecology and habitat The worm thrives in difficult environments with poor food nutrition. It is key to emergence of agriculture in the Amazon Basin, where soil is extremely poor. It may have facilitated the formation of ''terra preta''. On the other hand, the worm's adaptability has allowed it to spread to many disturbed tropical areas, especially urban sites and industrially-farmed areas. It is now considered an invasive species in many parts of the world. An endogeic worm creating globular casts, it is considered responsible for soil compact ...

Haplotaxida
The Haplotaxida are one of two orders within the annelid subclass Oligochaeta, the other being the Lumbriculida. No real common name exists, but they are simply referred to as haplotaxids. Given that the other clitellatan annelids are embedded between and around the Haplotaxida and Lumbriculida, the traditional ''Oligochaeta'' are a paraphyletic assemblage. Thus, the Haplotaxida might eventually be up-ranked to subclass status within the ''Clitellata'' or an expanded Oligochaeta, with the present suborders advancing to order rank. The latter – though without merging the ''Oligochaeta'' and ''Clitellata'' – has been proposed time and again in the past, most prominently for the distinct '' Moniligastrina.'' Families Of the four suborders of Haplotaxida, two are minor lineages, monotypic at family level. Another one, the Tubificina, is sizeable and contains the aquatic worms, while the fourth, the earthworms or Lumbricina, unites the bulk of the order's families: Suborder H ...

Earthworms
An earthworm is a terrestrial invertebrate that belongs to the phylum Annelida. They exhibit a tube-within-a-tube body plan; they are externally segmented with corresponding internal segmentation; and they usually have setae on all segments. They occur worldwide where soil, water, and temperature allow. Earthworms are commonly found in soil, eating a wide variety of organic matter. This organic matter includes plant matter, living protozoa, rotifers, nematodes, bacteria, fungi, and other microorganisms. An earthworm's digestive system runs the length of its body. An earthworm respires (breathes) through its skin. It has a double transport system made of coelomic fluid that moves within the fluid-filled coelom and a simple, closed circulatory system. It has a central and peripheral nervous system. Its central nervous system consists of two ganglia above the mouth, one on either side, connected to a nerve running along its length to motor neurons and sensory cells in each se ...
