Diver Shoots 'Extremely Rare Footage' of Mating Blue-Ringed Octopuses

An Australian diver captured some “extremely rare footage” of mating blue-ringed octopuses under Rye Pier in Port Phillip recently.

Jules Casey, who frequently posts underwater footage to her OneBreathDiver Instagram account, told Storyful that she and a group of divers spotted the encounter towards the end of their dive.

“Low on air, struggling with a GoPro that kept switching off … I managed to capture proof we saw them,” she wrote on Instagram. Credit: Jules Casey via Storyful
