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 w

Recruitment of juveniles takes place chiefly from June to August and most of the worms attain maturity in the following spring.

Growth of , (L.) (Oligochaeta, Naididae)The peculiarities of the growth in weight and length of . (L.) on the basis of observations in experimental vessels are considered. The growth of this species fits a parabolic curve. The equations relating weight to absolute growth rate as well as weight to duration of life are given.
