Try having no arms and eating a live octopus that's crawling around on your head with its tentacles.

Failure could mean it's your last supper. But a population of bottlenose dolphins off the coast of Australia has found a way to do it.

"These ones in south-west Australia have worked out: How do we catch them? How do we bite them? And how do we kill them so we can eat them?" said Kate Sprogis, a behavioral ecologist at Murdoch University Cetacean Research Unit who, with her colleagues, described the behaviour in a study published in Marine Mammal Science last month.

The recipe is as follows: Bite off the head. Shake the body. Toss until the arms are tenderised and the suction cups no longer function. Slam the body against the water repeatedly until it breaks into bite-sized pieces. Steps may be varied. Enjoy. The estimated preparation time ranges between one and six minutes.
