Least Concern The Southern Blue-ringed Octopus is most commonly found in cracks and crevasses in tidal rock pools along the south coast of Australia. They also enjoy being near seagrass beds. As an adult, it can grow up to 8 in long (top of the mantle to the tip of the arms) and on average weighs 1 ounce. Their diet consists mostly of lobsters, crabs and shrimp, as well as the occasional small fish. They are normally a docile species, but they are highly venomous, possessing venom capable of killing humans. Their blue rings appear with greater intensity when they become aggravated or threatened.

Fun Fact: When at peace, their coloring is often a drab, mucus-like color. However, once it feels sufficiently threatened, the blue-rings suddenly appear. These octopuses have an average of about 60 rings that have multilayer reflectors that allow them to flash a blue green color.
