For a part of the study on the accumulation of cobaly by cephalopods, uptake and excretion of innic 60Co taken up from seawater by Octopus vulgaris was exanined under labortory cinditions. Coblat-60 from seawater was accumlated remarkably in branchial heart that is a specific organ for cephalopods and the concentration factor of the nuclode by the organ attained to 33, 000 at 25th day in the uptake experiment at 20°C. Muscle showed the lowest concentration factor among the organs and tissues measered and the value was about 40 at 25th day. The 60Co ertention curve for whole body of the octopus was composed of two exponentail rate functions with biological half-life values of 1.2 (22%) and 190 days (78%).<br> The Sephadex gel chromatograms of 60Co extracted from seceral tissues and organs of the octopus suggest that the nuclide bound to different constituents on the respective tissues and organs. In muscle and liver, most of the muclide seems to be bound to the protein with low milecular weight (about several thousands MW). On the other hand, the nuclide in blood, internal medium, associated with a constituent with more than 80, 000 MW.
