In this paper the genome size evaluation is extended to 8 species of eutardigrades and one species of eterotardigardes in order to obtain a more comphrensive picture of minimun DNA content evolution in the phylum Tardigrada.Genome size and sperm cell morphology are correlated. In the phylum low genome size could be correlated to the high specialization of the phylum.
