Overview
The only member of this genus that deserves the common name "Giant octopus" is Enteroctopus dofleini. This holds the record of being the world's largest octopus: direct measurements were made of a live 71 kg (156.5 lb) individual.[1] This octopus had a total length near to 4 m (13 ft).
The remaining members of the genus are much smaller. E. megalocyathus has an average weight of 4 kg and a total length of 1 m.[2][3] E. magnificus has a total length of around 1.5 m.[4]
