title: [Turnover of internal water during the intermoult cycle of Sphaeroma serratum (Crustacea, Isopoda)].
abstract: 1. The relation between the wet weight and the tritiated water outflux could be expressed by the following equation: M = 5.67 W0.75 2. The diffusion water outflux undergoes variations along the molting cycle : stage C :320 microliter H2O/h/100 mg; D1: 459; D2 :477, E: 1900; A :1 551; B :544 microliter H2O/h/100 mg wet weight. 3. The internal water turnover rises sharply and heavily (lambda stage D2: 805%; lambda stage E :2621%) during the ecdysis of the back of the body. After ecdysis of the fore-part of the body it returns approximately toward the intermoult level within 5 or 6 days.
