Copper and protein in the hemolymph of the spiny lobsters (CRUSTACEA: PALINURIDAE)

BASTOS, Jose Raimundo; BEZERRA, Roberto Claudio Frota. Copper and protein in the hemolymph of the spiny lobsters (CRUSTACEA: PALINURIDAE). Arquivos de Ciências do Mar, Fortaleza, v. 10, n.2, p. 143-145, dez. 1970.Under a physiological point of view, copper is found in the majority of tissues of manne and terrestrial invertebrates, fulfilling the most varied functions. Severy (1923) found this element in the tissues of sixteen marine animais, in the most varied concentrations. Bryan (1964) studying the concentration of copper in the lobster Homarus vulgaris Miine Edwards, found it in approximately one dozen organs and tissues. The objective of this paper is to determine the average quantity of copper and protein in the hemolymph of spiny lobsters Panulirus argus (Latreille) and Panulirus laevicauda (Latreille), with the aim of making a comparison with other species studied, as well as verifying the importance of the simple correlation between total length of the animals and the quantity of copper and protein in the hemolymph
