Description

Octopus cyanea is commonly known as Reef Octopus, Day Octopus and Big Blue Octopus. As one of its common names suggests, this species is diurnal unlike most others which are nocturnal. 'Big Blue' only refers to the blue circles which are sometimes visible on the octopus, which is one of the few ways to distinguish it from O.vulgaris, which is similar in appearance in most other ways. O.cyanea occurs in temperate to tropical coastal waters in the Indo-Pacific region.
