How do I know that for sure? Well, recently his son, Robert Irwin, took to Instagram after recreating one of his dad's iconic photographs. And, this left social media users with a sense of nostalgia.
He was photographed cuddling the adorable critter and cradling it in his hands. At first glance almost everyone mistook Robert to be Steve and so did we.
The resemblance is just uncanny, isn't it? Just compare the two pictures above and decide for yourself.
