What's Dolphin for 'Flipper'?

Dolphins have the ability to call each other by name - just like humans! Scientists have found the mammals recognise themselves and other members of their species with special whistles. Up until now, humans were thought to be the only species that actually use names for one another.

Scientists say it's not unusual for animals to use sounds recognised by whole species, but it is extremely rare for species to use individual 'names' to communicate.

During the study experts caught a group of wild dolphins and recorded their calls. Scientists used a computer to copy the calls and then played them back to the dolphins. Most of the dolphins responded to the whistles of their relatives, suggesting they can recognise each other's signature whistle.

And if you thought this was uncannily human - what about pig makeovers?

Wilma, a Vietnamese pot-bellied pig, was rejected by two potential boyfriends so her keepers at Twin Lakes Park decided to give her a hand. The lonely sow has been given a bath and a trotter manicure to make her feel good. Wilma also had a special pig massage and her sty has been tidied. It's hoped the treats will do the trick and encourage Wilma to start a family.

Keeper Sue Statham said she hoped the makeover would boost Wilma's confidence: "We think Wilma is a very beautiful pot-bellied pig but she has been most unsuccessful in love. We are really hoping that by making her feel good about herself, she'll entice the boys into her sty."

Whatever next? Hamster spas? Hot tubs for depressed Koi carp?
