Classification

Family
Naididae

Tubifex tubifex, also called the sludge worm, sewage worm, or simply tubifex worm, is a species of tubificid segmented worm which inhabits the sediments of lakes and rivers on several continents. Tubifex tubifex is a slender segmented annelid that can reach lengths of up to about 20 cm. Taxonomy and classification Tubifex likely includes several species, but distinguishing between them is difficult because their reproductive organs, commonly used in species identification, are reabsorbed after mating, and because the external characteristics of the worm vary with changes in salinity.
