 Roy Mackal, a biochemist at the University of Chicago and a founding member of the International Society of Cryptozoology (as was F. G. Wood), decided to test the samples himself.In an issue of "Cryptozoology" in 1986, he wrote, "Gennaro carried out comparative histological examination of the tissue, and concluded that it most resembled contemporary octopus tissue.While these results were highly suggestive, further biochemical work was required for an unambiguous identification of the tissue."
