An unknown species of gigantic octopus has been hypothesized as a source of reports of sea monsters such as the lusca, kraken and akkorokamui as well as the source of some of the carcasses of unidentified origin known as globsters like the St. Augustine Monster. The species that the St. Augustine carcass supposedly represented has been assigned the binomial names "Octopus giganteus" (Latin: giant octopus) and "Otoctopus giganteus" (Greek prefix: oton = ear; giant-eared octopus), although these are not valid under the rules of the ICZN.
