The octopus is a powerful image that appears across many cultures. From the Norse Kraken to the Hawaiian creation myth, it seems humans have always held some awe and fear of octopuses. 

That reverence is not misplaced. Beyond its otherworldly looks, the octopus has many impressive qualities. 
Considered the smartest of all invertebrates, lab tests show that they are able to learn to run a maze and can be trained to recognize shapes and patterns. In nature, they have displayed problem solving skills and tool use. Specialized pigment and muscle cells in their skin allow them to mimic their backgrounds in both color and texture. These pigment cells also allows the naturally brown octopus to change colors to white when afraid, and red when angry. Although they have excellent vision, highly sensitive touch receptors in the suckers of their arms allow blind octopuses to differentiate between objects as well as a sighted octopus. Also equipped with chemoreceptors, an octopus can taste what it's touching. 

The most unexpected trait, however, is their ability to manipulate their bodies. They are completely malleable save for a small centrally located beak. Averaging two inches, so long as the beak can pass through an opening, the octopus can pull the rest of its body through to escape predators. Even knowing this, watching this octopus escape the deck of the boat is a sight to see.
