Pheretima
''Pheretima'' is a genus of earthworms found mostly in New Guinea and parts of Southeast Asia. Species belonging to the genus Pheretima have a clitellum, which is a band of glandular tissue present on segments 14 to 16. Individuals are hermaphroditic and reproduction can be either sexual or parthenogenetic. Female genital pores lie on the ventral surface of segment 14. A pair of male genital pores is situated ventrally on segment 18. Genital papillae may also be present ventrally. As with all earthworms, development of young is without a larval stage and takes place in cocoons. Pheretima are generally nocturnal, like most earthworms, and have an aversion to light. They come out only at night, and feed and reproduce only at night. Similar to most earthworms, they must keep their body surface wet to respire. They are also called farmer's friend as they help in making the soil porous for easy irrigation. Similar genera include ''Amynthas'', '' Archipheretima'', '' Duplodicodri ...

Pheretima Praepinguis
''Pheretima praepinguis'' is a huge earthworm about half meter long of genus Pheretima. ''Pheretima praepinguis'' lives in Mount Emei, Emei mountain, Sichuan Province, China, and is one of the most featured organisms living in the place. It's trivially called "Big Earthworm of Emei"() or "Toudilong" (, literally means "dragon which can go through the earth"). History In 1931, Yi Chen (), a honored Chinese biologist, researched some samples of an earthworm from Mount Emei, Sichuan Province. At that time, he suggested that it should be classified into ''Pheretima tschiliensis''. However, G. E. Gates found out that such earthworm is different with ''Pheretima tschiliensis''. They can be distinguished by the location of the primary spermathecal pores in parietal invaginations. He then named this earthworm after ''Pheretima praepinguis'' in 1935. Although Yi Chen insisted that ''Pheretima praepinguis'' is a synonym of ''Pheretima tschiliensis'' in an article published in 1936, this n ...

Kinabalu Giant Earthworm
The Kinabalu giant earthworm, ''Pheretima darnleiensis'', is a grey-blue coloured peregrine annelid. It is found widely in Southeast Asia, primarily in the Indo-Australasian Archipelago (e.g., Singapore, Sumatra, Java, Bali, Borneo, Sulawesi, the Philippines, some islands near New Guinea such as Darnley Island and Christmas Island), but also in Peninsular Malaysia. Records from the Caroline Islands and Fiji are believed to represent introductions This also applies to the eponymic Darnley Island record. On Mount Kinabalu, Borneo, the animal grows to a length of approximately 70 cm and lives in burrows in the soft and thick soils around Paka Cave shelter, at an altitude of 3,000 m above sea level. The earthworm's segments are encircled by numerous setae and its skin has a greenish iridescent gloss. Amongst the Kinabalu earthworm's natural predators is another large annelid, the Kinabalu giant red leech The Kinabalu giant red leech (''Mimobdella buettikoferi'') is a large ...

Hypoxanthine
Hypoxanthine is a naturally occurring purine derivative. It is occasionally found as a constituent of nucleic acids, where it is present in the anticodon of tRNA in the form of its nucleoside inosine. It has a tautomer known as 6-hydroxypurine. Hypoxanthine is a necessary additive in certain cells, bacteria, and parasite cultures as a substrate and nitrogen source. For example, it is commonly a required reagent in malaria parasite cultures, since '' Plasmodium falciparum'' requires a source of hypoxanthine for nucleic acid synthesis and energy metabolism. In August 2011, a report, based on NASA studies with meteorites found on Earth, was published suggesting hypoxanthine and related organic molecules, including the DNA and RNA components adenine and guanine, may have been formed extraterrestrially in outer space. The '' Pheretima aspergillum'' worm, used in Chinese medicine preparations, contains hypoxanthine. Reactions It is one of the products of the action of xanthine oxi ...

Earthworm
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 e ...

New Guinea
New Guinea (; Hiri Motu: ''Niu Gini''; id, Papua, or , historically ) is the world's second-largest island with an area of . Located in Oceania in the southwestern Pacific Ocean, the island is separated from Australia by the wide Torres Strait, though both landmasses lie on the same continental shelf. Numerous smaller islands are located to the west and east. The eastern half of the island is the major land mass of the independent state of Papua New Guinea. The western half, known as Western New Guinea, forms a part of Indonesia and is organized as the provinces of Papua, Central Papua, Highland Papua, South Papua, Southwest Papua, and West Papua. The largest cities on the island are Jayapura (capital of Papua, Indonesia) and Port Moresby (capital of Papua New Guinea). Names The island has been known by various names: The name ''Papua'' was used to refer to parts of the island before contact with the West. Its etymology is unclear; one theory states that ...
