Pheretima Praepinguis
''Pheretima praepinguis'' is a huge earthworm about half meter long of genus Pheretima. ''Pheretima praepinguis'' lives in 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 name is ubiqu ...

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 each s ...

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'', '' Duplodicodril ...

Mount Emei
Mount Emei (; ), alternately Mount Omei, is a mountain in Sichuan Province, China, and is the highest of the Four Sacred Buddhist Mountains of China. Mount Emei sits at the western rim of the Sichuan Basin. The mountains west of it are known as Daxiangling. A large surrounding area of countryside is geologically known as the Permian Emeishan Large Igneous Province, a large igneous province generated by the Emeishan Traps volcanic eruptions during the Permian Period. Administratively, Mount Emei is located near the county-level city of the same name (Emeishan City), which is in turn part of the prefecture-level city of Leshan. It was made a UNESCO World Heritage Site in 1996. As a sacred mountain Mount Emei is one of the Four Sacred Buddhist Mountains of China, and is traditionally regarded as the bodhimaṇḍa, or place of enlightenment, of the Bodhisattva Samantabhadra. Samantabhadra is known in Mandarin as Pǔxián Púsà (). Sources of the 16th and 17th centuries all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sichuan (; zh, c=, labels=no, ; zh, p=Sìchuān; alternatively romanized as Szechuan or Szechwan; formerly also referred to as "West China" or "Western China" by Protestant missions) is a province in Southwest China occupying most of the Sichuan Basin and the easternmost part of the Tibetan Plateau between the Jinsha River on the west, the Daba Mountains in the north and the Yungui Plateau to the south. Sichuan's capital city is Chengdu. The population of Sichuan stands at 83 million. Sichuan neighbors Qinghai to the northwest, Gansu to the north, Shaanxi to the northeast, Chongqing to the east, Guizhou to the southeast, Yunnan to the south, and the Tibet Autonomous Region to the west. In antiquity, Sichuan was the home of the ancient states of Ba and Shu. Their conquest by Qin strengthened it and paved the way for Qin Shi Huang's unification of China under the Qin dynasty. During the Three Kingdoms era, Liu Bei's state of Shu was based in Sichuan. The area was de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
