Octopus cyanea, also known as the big blue octopus[3] or day octopus,[4] is an octopus in the family Octopodidae. It occurs in both the Pacific and Indian Oceans, from Hawaii to the eastern coast of Africa.[5] O. cyanea grows to 16 cm in mantle length with arms to at least 80 cm.[5] This octopus was described initially by the British zoologist John Edward Gray in 1849; the type specimen was collected off Australia and is at the Natural History Museum in London.[6]
