I think this is often pre-emptive aggression, meant to signal ‘don’t mess with me,’ rather than aggression seriously meant to harm the ‘invader.


A swim on holiday at a Western Australia beach. My guess is that the octopus here is sending a warning meaning ‘back off’ … Octopuses will lunge or shoot an arm out when they feel a fish, another octopus or a human is in their space. The octopus lashed out at us, which was a real shock, geologist and author Lance Karlson said. Speaking to The New York Times, Peter Ulric Tse, a professor of cognitive neuroscience at Dartmouth College who studies octopus cognition, said that octopuses, in general, “can express what we would call aggression when they feel threatened or when they feel their territory is under threat.” Tse said that the behavior captured in Karlson’s video is likely a warning not an attempted attack. This species, as seen in the video, is “commonly found in and around inshore reef systems and sandy benthos” and it “completes its life cycle in nearshore and continental shelf waters.” This region is home to the Western Australian common octopus - closely related to the common Sydney octopus but recently determined to be its own species. In a March 19 post on Instagram, Karlson summarized the creature as the angriest octopus in Geographe.

Karlson had a close encounter with an octopus in Geographe Bay in Dunsborough, Western Australia, the Daily Mail reported Wednesday. The video was filmed in Dunsborough, Western Australia. Fascination with an octopus can lead to a painful experience, as author Lance Karlson found out recently. The tentacles left stinging red welts on his skin, which Karlson said only eased after he poured cola over them. The creature came after him again later and struck him on the arm, before whipping his neck and upper back.

Karlson posted his video on Instagram, where it has been viewed 60,000 times. A post shared by Lance Karlson Author (lancekarlson) Geologist Lance Karlson stepped into the wrong neighborhood in Australias Geographe Bay when he approached this octopus with his 2-year-old. Realizing the creature was, in fact, an octopus, he started filming it - just in time for the angry invertebrate to launch itself at him. On March 18, 34-year-old Lance Karlson was walking on the beach and looking for somewhere to swim with his two-year-old daughter in Geographe Bay, a popular snorkeling spot about 140 miles south of Perth, when he saw what he thought was a stingray leap from the water. (CNN) - Considered by biologists to be some of the most intelligent invertebrates, octopuses are normally playful and inquisitive.īut an Australian geologist saw another side to the marine creatures, when one octopus defended its home in Western Australia rather aggressively. Considered by biologists to be some of the most intelligent invertebrates, octopuses are normally playful and inquisitive.
