— Quantitative and qualitative ultrastructural data from the spermatozoa of 11 oligochaete species, representing all orders (Tubificida, Lumbriculida, and Haplotaxida, yielded a single most parsimonious tree, using the Wagner‐tree (PAUP) method o

Despite the wide use of the tubificid oligochaete Tubifex tubifex in eco-toxicological studies, the reproductive strategy adopted by the species, that can reasonably be assumed to be the key to its ecological success, is still not well investigated.
