Blue-Ringed Octopus Uses Camouflage in Port Phillip Bay

A scuba diver noticed a venomous octopus using camouflage to blend in with its surroundings in Port Phillip Bay, Victoria.

This footage, shot by Jules Casey, shows a blue-ringed octopus slowly emerging from a selection of shells to reveal its true colors when a camera approaches.

“This was the first time I’d ever witnessed this behavior,” Casey wrote on an Instagram post that featured the video. Credit: Jules Casey via Storyful
