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 is trivially called "Big Earthworm of Emei"() or "Toudilong" (, literally means "dragon which can go through the earth"). History In 1931, Yi Chen (), an honored Chinese biologist, researched some samples of an earthworm from Mount Emei, Sichuan Province. At that time, he suggested that it should be classified as ''Pheretima tschiliensis''. However, G. E. Gates Gordon Enoch Gates (11 January 1897 – 11 June 1987) was an American zoology, zoologist. He is known for his Taxonomy, taxonomic work on the Oligochaeta and for being a "world authority" on the subject. He published in his field for nearly 60 yea ... found out that such earthworm is different with ''Pheretima tschiliensis''. They can be distinguished by the location of the primary spermatheca ...

Earthworm
An earthworm is a soil-dwelling terrestrial invertebrate that belongs to the phylum Annelida. The term is the common name for the largest members of the class (or subclass, depending on the author) Oligochaeta. In classical systems, they were in the order of Opisthopora since the male pores opened posterior to the female pores, although the internal male segments are anterior to the female. Theoretical cladistic studies have placed them in the suborder Lumbricina of the order Haplotaxida, but this may change. Other slang names for earthworms include "dew-worm", "rainworm", "nightcrawler", and "angleworm" (from its use as angling hookbaits). Larger terrestrial earthworms are also called megadriles (which translates to "big worms") as opposed to the microdriles ("small worms") in the semiaquatic families Tubificidae, Lumbricidae and Enchytraeidae. The megadriles are characterized by a distinct clitellum (more extensive than that of microdriles) and a vascular system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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'', '' Duplodico ...

Sichuan University
Sichuan University (SCU) is a public university in Chengdu, Sichuan, China. The university is affiliated with and funded by the Ministry of Education. The university is part of Project 211, Project 985, and the Double First-Class Construction. In 1994, the then Chengdu University of Science and Technology and then Sichuan University merged to form Sichuan Union University (which was renamed Sichuan University in 1998). In 2000, the then West China University of Medical Sciences and then Sichuan University merged to establish the current form of Sichuan University. History Sichuan University is one of the earliest institutions of higher education in China. Its earliest predecessor was the Sichuan Chinese and Western School (四川中西學堂), a school established in 1896 that combined traditional and modern methods of education. In 1902, it was merged with two traditional Chinese academies, the Jinjiang Shuyuan (錦江書院, founded 1740) and the Zunjing Shuyuan (尊經書 ...

Mount Emei
Mount Emei (; zh, c=峨眉山, p=Éméi shān, O2-mei2 shan1), alternatively 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. Name Emei means "moth-browed". Relevance to Buddhism Chinese people offer burning sandalwood near the mountain to send their "prayers to heaven".

Sichuan Province
Sichuan is a Provinces of China, province in Southwestern China, occupying the Sichuan Basin and Tibetan Plateau—between the Jinsha River to the west, the Daba Mountains to the north, and the Yunnan–Guizhou Plateau to the south. Its capital city is Chengdu, and its population stands at 83 million. Sichuan neighbors Qinghai and Gansu to the north, Shaanxi and Chongqing to the east, Guizhou and Yunnan to the south, and Tibet Autonomous Region, Tibet to the west. During antiquity, Sichuan was home to the kingdoms of Ba (state), Ba and Shu (kingdom), Shu until their incorporation by the Qin (state), Qin. During the Three Kingdoms era (220–280), Liu Bei's state of Shu Han, Shu was based in Sichuan. The area was devastated in the 17th century by Zhang Xianzhong's rebellion and the area's subsequent Qing dynasty, Manchu conquest, but recovered to become one of China's most productive areas by the 19th century. During World War II, Chongqing served as the temporary capital o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
