Tubifex tubifex ，也称为污泥蠕虫病毒，蠕虫或污水处理，是一个物种的tubificid分割的蠕虫，栖息沉积物湖泊和河流的几个大洲。吨tubifex可能包括若干种，但它们之间的区别非常困难，因为生殖器官，常用的品种鉴定，正在吸收交配后，由于外部特征的蠕虫随盐度的变化。这些蠕虫进食沉积物，有选择地消化细菌，吸收分子通过体壁。
该蠕虫病毒可以生存几乎没有氧气的血红蛋白挥舞着丰富尾目的，利用一切可用的氧气。它们也可以生存受到严重污染的地区的有机物，几乎没有其他物种能承受。通过形成一个保护囊肿并降低其代谢率，吨tubifex才能生存干旱和粮食短缺。包囊也可能分散功能的蠕虫病毒。
利用
生态，蠕虫病毒是重要的食物来源的水蛭，甲壳类动物，昆虫和鱼类。 Tubifex出售鱼类食品在生活和冷冻干燥， pelletised形式。虽然蠕虫比较容易的文化，他们可能会花上一个月才能收获。虽然他们是高蛋白质，它们不是建议供人食用的原因是高盐分含量。

Tubifex tubifex, also called the sludge worm, or sewage worm, is a species of tubificid segmented worm that inhabits the sediments of lakes and rivers on several continents. T. tubifex probably includes several species, but distinguishing between them is difficult because the reproductive organs, commonly used in species identification, are resorbed after mating, and because the external characteristics of the worm vary with changes in salinity. These worms ingest sediments, selectively digest bacteria, and absorb molecules through the body wall.
The worms can survive with little oxygen by waving hemoglobin rich tail-ends to exploit all available oxygen. They can also survive in areas heavily polluted with organic matter that almost no other species can endure. By forming a protective cyst and lowering its metabolic rate, T. tubifex can survive drought and food shortage. Encystment may also function in the dispersal of the worm.
[edit] Uses
Ecologically, the worms are important as a source of food for leeches, crustaceans, insects, and fish. Tubifex are sold as fish-food in both live and freeze-dried, pelletised forms. While the worms are relatively easy to culture, they can take up to a month before they can be harvested. Although they are high in protein, they are not recommended for human consumption due to a high salt content.
