Cephalopods: Day Octopus (Octopus cyanea)

Day octopuses are intelligent and sophisticated creatures that live in the ocean. With 500 million neurons, 60% of which can be found in their arms, they have one of the highest neuron-to-body ratios among animals. They can change their skin color and texture to camouflage with their environment, and their arms have suckers along their entire length, allowing them to “walk” across coral reefs. The largest day octopus grows up to 4-5 pounds and has an arm span of 3ft. In addition to using their arms to move around, they also use their beaks to pick apart crustaceans and fish for food. Lastly, these fascinating creatures have only a single photoreceptor, meaning they can only see black and white.

In Hawaiian culture, the day octopus is seen as a deity of the ocean known as Kanaloa. An old saying, “Pua ke ko, ku mai ka he’e,” translates to “When the sugarcane flowers, the octopus appears,” meaning that when sugarcane starts flowering, it’s a good time for fishing since the octopus will likely make an appearance. Some of the cephalopods you can find in Hawaii are:

  • Day Octopus (Octopus cyanea) or heʻe mauli
  • Night Octopus (Callistoctopus ornatus, ornate octopus) or heʻe pūloa
