The percentage of water in the total living body weight is restricted within a narrow range for each species, even in snails cultured under differing controlled ionic concentrations in the medium. The water level in Helisoma trivolvis is consistently higher than in Biomphalaria pfeifferi and B. glabrata under the same culture conditions.The whole cationic fraction of the total osmoconcentration of the haemolymph is maintained at a constant hypertonic level, even though individual cation levels vary with the cationic composition of the surrounding medium. 相似文献
