Octopus 'Slaps' Partner and Makes Swift Exit Following Hours-Long Mating Session

The moment an octopus broke free from a mating session with its partner was captured on film by a diver based on the Mornington Peninsula in Victoria, who said the encounter between the pair lasted for “several hours”.

Posting the footage to Instagram, Jules Casey told her followers, “When I found them they were already together. I watched for about an hour then went home, changed into a dry wetsuit and had lunch. They were still going when I returned.”

She added that her footage takes in “the final minute” of the mating ritual, as one of the octopus “slaps” the other in the face when they’ve “had enough”, before quickly dashing away into the ocean.

Live Science notes in an online article that the mating process for octopuses “may take up to several hours, depending on the species.”

Casey, a keen diver, and freediver, 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.
