Potential age of aquatic Oligochaetaely earlier. The zooids of paratomic species live some weeks or months, their clones usually less than a year, rarely for some years. In the species with facultative architomy (fragmentation) the clonal age also exceeds that of the individual, both lasting for several years. The actual lifetime of worms in nature may be shorter than in cultures.

Two atavistic characters of some Lumbriculidae and their importance for the classification of Oligochat the posterior location of funnels and sperm ducts is the result of a forward shift of the atria, which refutes Stephenson’s supposition that the Lumbriculidae is the most archaic family of the present-day Oligochaeta.
