By Sarah Griffiths for MailOnline. Humans may have their quirks and kinks, but sex in the animal kingdom can be truly strange and excruciatingly painful. Scroll down for video. The Argonaut octopus' pictured mating ritual has been voted the strangest.
Female Octopus Strangles Mate, Then Eats Him - Scientific American Blog Network
The male blanket octopus faces a significant gender imbalance - he is just two centimetres long, while the female of the species can measure up to two metres. And as if being times smaller than his mate wasn't bad enough, he dies right after having sex with her. A senior curator at the Melbourne Museum, Mark Norman, who recently found a living specimen on the Great Barrier Reef, said that until now the male had only been discovered dead in trawls and plankton nets. His achievement in capturing and photographing a live one has been documented in a recent paper for the New Zealand Journal of Marine and Freshwater Research. According to the article, the male blanket octopus is, technically speaking, "the most extreme example of sexual size-dimorphism in a non-microscopic animal Dr Norman said: "There's no other critters on that scale that have such a significant difference between the male and female. The two-metre female weighs at least 10, times as much as the male, sometimes up to 40, times as much.
Octopus sex is simple, dull and quick - at least that's what scientists used to think. Instead, it turns out to be complex, sophisticated and rife with petty rivalries. In the most detailed research ever conducted on this topic in the wild, UC Berkeley biologists focused on the mating behavior of the Abdopus aculeatus, one of more than species of octopus. They were stunned at what they learned.
Octopuses do the darndest things. Like kill their mate during mating — by strangling him with three arms , according to new observations from the wild. Enterprising scientists Christine Huffard and Mike Bartick watched wild octopuses in action.
