Robert Irwin has shared a striking tribute to his late father Steve Irwin, posting a photo of the pair feeding the same crocodile at Australia Zoo.
"Dad and me feeding Murray... same place, same croc - two photos 15 years apart," he captioned the image, which has since gone viral.
This is amazing," wrote one commenter, who summed up the sentiments of many. "You are following in his footsteps even down to the stance."
On Twitter, Robert's mother, Terri, also shared her pride.
"Steve's mission is in good hands," she wrote.
The 15-year-old's post has left many around the world misty-eyed - and bursting with pride.

I hope you keep doing what makes you happiest man. Your whole family is and has always been a huge positive influence on me and many others around the globe. Keep your passion alive! :)— Jordan Sweeto (@JordanSweeto) July 3, 2019
Robert was only two years old when his father died aged 44 after being stung by a stingray in 2006 while filming the documentary Ocean's Deadliest. Irwin's family, including wife Terri, 54, and daughter Bindi, 20, have continued his legacy at Australia Zoo, often posting updates to social media to honour his memory and his work.
In an interview with PEOPLE last year, Robert noted that he loves calling Australia Zoo, home.
"After school, I'll go around on my scooter and jump in with the tortoises to say 'g'day!' or wrangle some snakes," he said. "Every day is a new adventure."
In June, Robert posted a note the Irwins received from a flight attendant, "Little gestures like this really mean a lot. It warms my heart to see people who take a little bit of time to do something kind. Thank you Carolyn."
And on his father's birthday in February, Robert shared a sweet throwback photo. "It warms my heart to see so many people celebrating his life and the difference he made," Robert wrote. "Together we'll keep his legacy alive forever."
A talented photographer, Robert is also passionate about encouraging young people to start snapping. "Capturing the beauty of this incredible natural world through photos has been my passion for years, " he posted on Instagram. "Now I hope to encourage other young people to pick up a camera and get outdoors, it's such a rewarding experience!"
