This is a solitary species but they can occasionally be found in pairs. They are found mostly during the day, walking on their lower arms and with their back mantle flapping along the sandy bottoms of the Strait. They hunt for small fish and crustaceans. Their flamboyant colours are displayed when alerted to warn potential predators of their toxicity. The toxins contained in their muscles have the same lethality as those possessed by their cousin, the blue ring octopus. They can be observed laying eggs under empty coconut shells from January to July.
