“…and exhibit channel-shaped cell invaginations and a high endocytotic activity (Meister 1977;Sundermann 1980). The cytomorphological differentiation of the ovoid cells and the electron-microscopical localization of ring-shaped inclusions corresponding to the size of hemocyanin subunits, within the electron-dense bodies, (Schipp and Schäfer 1969) support our hypothesis that the branchial hearts are involved in hemocyanin catabolism in dibranchiate cephalopods (Schipp and Hevert 1978).…”

The present study confirms previous investigations that demonstrated a high copper content in the branchial heart and its appendage, and that gave the first indication that this organ complex might be involved in hemocyanin metabolism in Sepia officinalis L. Immunocytochemical localization of hemocyanin molecules within the endocytotic lysosomal system of the ovoid cells and tracer experiments with 125I-labeled Sepia hemocyanin suggest its endocytotic uptake. Energy-dispersive X-ray microanalysis and histochemical methods reveal a high copper content within the ovoid cells of the branchial heart. In view of the turnover of the respiratory pigment in the branchial heart of Sepia officinalis L., we believe that the ovoid cells are a site of hemocyanin catabolism.

“…In the Coleoidae species, branchial hearts have been reported to concentrate essential elements such as Fe and Cu (Fox & Updegraff 1943, Ghiretti-Magaldi et al 1958, Nardi & Steinberg 1974, Schipp & Hevert 1978, Miramand & Bentley 1992. These organs also concentrate toxic and radioactive elements such as 241 Am, Co, Ni, 239-240 Pu and V , Miramand & Guary 1980, Guary et al 1981, Guary & Fowler 1982, Miramand & Bentley 1992.…”

The studies concerning trace elements in cephalopods molluscs are limited to species targeted by commercial fisheries such as the cuttlefish Sepia officinalis (Decleir et al 1978, Schipp & Hevert 1978, Miramand & Bentley 1992, Bustamante 1998, the octopuses Octopus vulgaris and Eledone cirrhosa (Ghiretti-Magaldi et al 1958, Rocca 1969, Renzoni et al 1973, Froesch & Packard 1979, Miramand & Guary 1980, Miramand & Bentley 1992, Barghigiani et al 1993, Rossi et al 1993, Bustamante 1998, some Ommastrephid squids (Martin & Flegal 1975, Smith 1983, Smith et al 1984, Finger & Smith 1987, Yamada et al 1997, Bustamante 1998 and some Loliginid squids (Martin & Flegal 1975, Yamada et al 1997, Bustamante 1998.

: Soils in New Caledonia are particularly rich in metals among which Fe and Ni are intensively exploited. Due to important natural erosion in tropical latitudes and to mining activities, coastal waters are enriched in Co, Cr, Fe and Ni. In deeper waters lives a cephalopod species which is considered as a living fossil, the nautilus Nautilus macromphalus. In this study, 12 traces elements were analysed in the tissues of 4 nautilus specimens. Results showed high metal concentrations compared to data available for cephalopod from temperate waters. These concentrations were often in the same order than those encountered in bivalves or gastropods from contaminated areas. Relatively high concentrations of Ni and Cr in the hemolymph strongly suggest a high exposure of N. macromphalus to these metals. Among the tissues, the digestive gland have the highest concentrations of Cd, Co, Fe, V and Zn while for Ag, Al, As, Cr and Ni, renal and pericardial appendages exhibited the highest values. Despite this, the digestive gland contained the largest quantities of all metals with the exception of As and Mn which were mainly found in the body 2 muscular remains. These results highlighted the major role of digestive gland and excreting organs in the metabolism of metals in these cephalopod species.

Cytobiological experiments using isotopic- and cytochemical-labeled Sepia hemocyanin as well as immunocytochemical localization of the respiratory pigment were carried out to investigate the function of the hemocytes in hemocyanin metabolism of the common cuttlefish Sepia officinalis. For comparison, the rhogocytes (ovoid cells) of the branchial heart complex were included in this study. Hemocyanin molecules were immunocytochemically detected in the lysosomal compartment of the rhogocytes and, at lower levels, in adhesive and circulating hemocytes. (125)I-labeled Sepia hemocyanin was taken up by the rhogocytes only, whereas gold- and/or fluorescein-labeled Sepia hemocyanin was solely taken up by the adhesive and the circulating hemocytes, even though the level of uptake is different. There are also differences in the uptake of pure gold particles and/or fluorescein between rhogocytes and hemocytes. These findings give evidence that circulating and adhesive hemocytes of the branchial heart complex are not involved in hemocyanin turnover, but are a component of the cellular defense and detoxification system of adult coleoid cephalopods.
