What is this? News at a Glance explained.
When double amputee Nadya Vessey turned to the special effects team behind The Lord of the Rings to help her make a prosthetic, they came up with something special: a mermaid tail.
Ms Vessey, from Auckland, New Zealand, had both legs removed by the age of 16 due to a medical condition. But she is still a keen swimmer
Now in her fifties, Ms Vessey was pleasantly surprised when Weta Workshop agreed to give the mermaid tail a go, promising to make it as realistic as possible.
