Abstract: | The relationships between individual dry weight and bodycontent of the essential metals copper and zinc and of therespiratory pigment haemocyanin have been investigated in fourBritish species of caridean decapod crustaceans, Palaemonelegans, Palaemon longirostris, Palaemonetesvarians and Crangon crangon. Also considered were thebody concentrations of soluble copper and copper associatedwith haemocyanin. These decapods regulate total bodyconcentrations of copper and zinc to approximately constantlevels which can vary interspecifically. An attempt is made tointerpret these regulated concentrations in terms of essentialrequirements for the metals in the physiological functioningof haemocyanin, the body concentration of which variesinterspecifically and intraspecifically with environmentalvariables. |
