Surprise! Blue-Ringed Octopus Shakes Off Shell-and-Seaweed Camouflage

A freediver exploring the world beneath the waves of Victoria’s Port Phillip Bay captured the moment a blue-ringed octopus shook off the shells and seaweed that had made it “almost impossible to see”.

Jules Casey, who shot this video, wrote of the experience, “A Blue Ringed Octopus waking up from a deep sleep. Completely covered in shells & weed [its camouflage] making it almost impossible to see until it moves.”

Blue-ringed octopuses are among the most venomous octopus species and dwell in tide pools and shallow rocky reefs. With no known anti-venom, they can be deadly to humans.

Casey often posts footage of what she sees below the waves at Port Phillip Bay to her OneBreathDiver Instagram account, where she has over 90,000 followers.
