title: The physical characteristics of the haemolymph in Porcellio spinicornis say (Porcellionidae, Isopoda).
abstract: Absolute haemolymph volume in Porcellio spinicornis, as determined by the 14C-dilution and the haemolymph sodium estimation techniques, ranged, on the average, from 8.1 microliter in the 6th growth--stage to 15.06 microliter in the 9th growth--stage. The mean haemolymph volume per cent for all growth--stages (6th-9th) amounted to 33.78. The haemolymph pH varied from 6.42 to 6.54, osmotic pressure from 221 to 256 mM NaCl equivalents and the specific gravity from 1.031 to 1.052.
