This beautiful and incredibly intelligent creature inhabits coastal regions of Western North America and Eastern Asia. It is one of the largest of all octopuses and is renowned (like many of the cephalopods) for it's ability to change it's body's colour and texture as a defence mechanism. The intelligence of these creatures is not very well understood however their incredible powers of shapeshifting are indicative of how much really goes on in their neuro system! More research needs to go into how intelligent cephalopods are. Their intelligence is often dismissed, largely because of how differently these organisms express their intelligence from vertebrates.
The following video highlights the octopus' ability to change it's shape. The octopus is visible from 0:08 in the video. Try and spot it! you will be amazed!!
