Saying that Robert Irwin and Steve Irwin look similar won't come as a surprise to anyone - they're father and son after all.
But have you ever noticed how similar they actually look?
After an interview with the Irwins on The Sunday Project, Lisa Wilkinson shared a snap of the father and son duo side-by-side at the same age - and fans can't believe their eyes.
She captioned the uncanny snap: "That's Robert on the left and his dad Steve around the same age on the right," Wilkinson wrote in the caption. "Amazing."
Fans flooded the comment section of the post, blown away by the similarities.
One said: "I swore I was looking at two photos of Robert!"
During the interview, Robert revealed that he still has a strong connection to his father, despite Steve's death back in 2006.
"I feel closest to Dad when I'm working with the animals that he really loved," he said.
Robert makes a lot of TV appearances, mostly in the US, to try and keep his dad's conservation dreams alive.
He has appeared on The Tonight Show Starring Jimmy Fallon several times over the past two years, terrifying Jimmy and his guests every time.
