Soil Organisms and Species Earthworm (Lumbricus terrestris). The soil is also home to many different types of living things. An individual living thing is known as an organism, and all organisms of the same type are known as a species. A species is defined as all organisms that can reproduce with one another and produce fertile offspring.There are billions of earthworms in the world-each earthworm is an individual organism, but they are all members of the earthworm species. species is defined as all organisms that can reproduce with one another and produce fertile offspring.

Taxonomy Only the Turbellarians are non-parasitic worms in this phylum, which means they are seen as free living. There are about 3,000 Turbellarians species known to man, such as this tiger flatworm (pictured to the right), and as far as scientists are concerned, the other three classes of Platyhelminthes derived from the Turbellarians.

Earthworm Theoretical cladistic studies have placed them, instead, in the suborder Lumbricina of the order Haplotaxida, but this may again soon change. Folk names for the earthworm include dew-worm, rainworm, night crawler, and angleworm (due to its use as fishing bait).epending on the species, an adult earthworm can be from 10 mm (0.39 in) long and 1 mm (0.039 in) wide to 3 m (9.8 ft) long and over 25 mm (0.98 in) wide, but the typical Lumbricus terrestris grows to about 360 mm (14 in) long.

Pinworm (parasite) This article is about the nematode of the family Enterobius, known as pinworm in the US. For the different nematode known as pinworm in the rest of the world, see Strongyloides stercoralis. The pinworm (genus Enterobius), also known as threadworm (in the United Kingdom and Australia) or seatworm, is a parasitic worm. It is a nematode (roundworm) and a common intestinal parasite or helminth, especially in humans. The medical condition associated with pinworm infestation is known as enterobiasis (a type of helminthiasis) or less precisely as oxyuriasis in reference to the family Oxyuridae.

Earthworm An earthworm is a tube-shaped, segmented worm found in the phylum Annelida. They are commonly found living in soil, feeding on live and dead organic matter.Its digestive system runs through the length of its body. It conducts respiration through its skin.arthworms are hermaphrodites, that is, they have both male and female sexual organs. The sexual organs are located in segments 9 to 15. Earthworms have one or two pairs of testes contained within sacs. The two or four pairs of seminal vesicles produce, store and release the sperm via the male pores.
