Enteroctopus dofleini
''Enteroctopus dofleini'', also known as the Giant Pacific octopus (GPO) or North Pacific Giant octopus, is a large marine cephalopod belonging to the phylum Mollusca, and genus ''Enteroctopus''. Its spatial distribution includes the coastal North Pacific, along California, Oregon, Washington, British Columbia, Alaska, Russia, northern Japan and Korea. It can be found from the intertidal zone down to depths of 2,000 m (6,600 ft), and is best adapted to cold, oxygen-rich water. It is arguably the largest octopus species, based on a scientific record of a 71 kg (156 lb) individual weighed live.〔Cosgrove, J.A. 1987. Aspects of the Natural History of ''Octopus dofleini'', the Giant Pacific Octopus. M.Sc. Thesis. Department of Biology, University of Victoria (Canada), 101 pp.〕 The alternative contender is the seven-arm octopus (''Haliphron atlanticus'') based on a 61 kg (134 lb) carcass estimated to have a live mass of 75 kg (165 lb). However, a number of questionable size records would suggest ''E. dofleini'' is the largest of all octopus species by a considerable margin.〔Norman, M. 2000. ''Cephalopods: A World Guide''. Hackenheim, ConchBooks, p. 214. ISBN 978-3-925919-32-9〕
==History==
The octopus (/ˈɒktəpʊs/ or /ˈɒktəpəs/; plural: octopuses, octopi, or octopodes) were named by ancient Greeks, meaning "eight foot". The preferred plural is octopuses, although octopi and octopodes are also recognized. Octopuses were depicted on Cretan and Minoan coins (1650 to 1500 BC and 1450 to 1375 BC) and were painted onto jars in the Mycenaenera (circa 1200 to 1100 BC).〔 Cephalopods have been around for 500 million years, although octopus ancestors were in the Carboniferous seas around 300 million years ago.〔 The oldest octopus fossil, ''Pohlsepia'' can be found at the Field Museum in Chicago.〔
