We already knew that dolphins were intelligent - and now we know that they are excellent chefs as well.
A female bottlenose dolphin has been observed in the wild using an amazingly complex method to catch and prepare cuttlefish.
She first herded the fish out of weeds and on to a sandy patch of sea floor.

Then she pinned it down with her snout, before whipping around and killing it with a deft blow of her tail.
Next she tossed it around in the water to flush out the foultasting ink, and then finally scraped it on the sand to strip out the inedible bone.

After all this, she was left with a tasty, tender mouthful.
The team of scientists from Australia and Britain, who studied the dolphin in the Spencer Gulf in South Australia, were amazed at her precise and elaborate method.
'This is a sign of how well their brains are developed,' said study co-author Dr Mark Norman, curator of molluscs at the Museum of Victoria.
'It's a pretty clever way to get pure calamari without all the horrible bits.'
They saw the dolphin going through the same process in 2003 and 2007, so are convinced it was her usual system, not a one-off effort, according to the report in the journal PLoS One.
Dr Norman and his colleague Tom Tregenza from the University of Exeter, believe that 'some or all of this behavioural sequence' would be performed by other dolphins as well.
It is not the first time that the species has astonished researchers - a 2005 study showed that mother dolphins were teaching their daughters how to break off sea-sponges to fit over their snouts, to protect them as they probed the sea floor for food.
