The samples were found to be "masses of virtually pure collagen" and not to have the "biochemical characteristics of invertebrate collagen, nor the collagen fiber arrangement of octopus mantle." The results suggest the samples are "the remains of the skin of an enormous warm-blooded vertebrate." The authors conclude that "there is no evidence to support the existence of Octopus giganteus" and concur with Verrill (1897) and Lucas (1897) that the St. Augustine carcass was "the remains of a whale, likely the entire skin [blubber layer] . . . nothing more or less." 2004 analysis {| class="wikitable" |+Comparative amino acid compositions of the blob tissue samples following acid hydrolysis (values are amino acid residues/1000 residues) |- !
