    Dendrobaena mrazeki is an endemic earthworm species inhabiting dry habitats such as pine and thermophilous oak forests in Central Europe. 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.
