Bindi Irwin is voicing a character in a Marvel television show.
The conservationist, 24, has recorded a voice-over for the character Isla Coralton, who is an oceanographer, on the next episode of Spidey and his Amazing Friends.
The computer-animated children's show, which features young versions of the Marvel superhero characters, airs on the Disney Junior network.
Bindi said Isla was the perfect role for her because they both 'love wildlife and wild places' and are 'passionate' about making a difference.
'Being an enormous Marvel fan, it is an honour to be part of the extraordinary world of Spidey and his Amazing Friends,' she said in a video posted to Instagram.
'I have an eight-month-old daughter [Grace Warrior]. We watched a couple of episodes and she already enjoys it, which is incredible.'
Bindi added: 'It is so important to empower the next generation to love our planet.
'To have that respect for all living creatures and the environment that they call home.
'And I think that this series does a really, really good job at introducing those ideas.'
It comes after Bindi and her husband Chandler Powell, 25, took their daughter Grace Warrior to Lady Elliot Island in Queensland on Wednesday.
There, the child was seen walking unassisted as the family strolled around several locations on the island before standing on the water's edge to watch the sunset.
Lady Elliot Island is the same place the Irwin family visited King Charles III during his last royal tour of Australia.
Charles, then the Prince of Wales, spent a day with the Irwins during his tour in 2018.
They likely found in Charles a kindred spirit, as he has long advocated for wildlife conservation and other environmental issues long before it was politically trendy.
Bindi's younger brother Robert Irwin, 18, said at the time he was 'truly honoured' to meet Charles who was joined on the trip by his wife Camilla, Duchess of Cornwall, and speak to 'such a passionate and influential person' about the Great Barrier Reef.
