One of the ocean's most venomous animals, the blue-ringed octopus hunts small crabs and shrimps among the wreck timbers during the day, its iridescent blue rings flashing only when agitated. Lankayan's boatyard wreck hosts a resident population that shelters in the engine casing and cavities formed by collapsed planking. Divers who observe from a safe distance are rewarded with extended behavioural sequences including colour-change displays and prey capture.
