Metabolically, D. mrazeki showed some features typical for endogeic species and some of epigeic ones. In comparison with the related Dendrobaena octaedra, D. mrazeki was a larger earthworm with fresh body mass of adult and subadult individuals of W = 0.59±0.05 g. Its body mass-specific oxygen consumption (M/W = 48±5 µl O2g-1h-1, at 15 °C) was the lowest of all earthworms studied(Aporrectodea caliginosa, A. rosea, D. octaedra, Lumbricus castaneus, L. rubellus, Octolasion lacteum), being strongly dependent on W (b from the equation M/W = aWb about -0.8). D. mrazeki had low relative water content (77.4% of fresh body mass) and small relative amount of dry weight of the intestinal content(20.1% of dry body mass), which is similar to the epigeic D. octaedra.
