Steve Irwin's son makes wildlife pilot

Steve Irwin's son Bob is to follow in his late father's footsteps by starring in a wildlife show.

A pilot for the series previewed on Australian news show 60 Minutes this week, showing the four-year-old wrestling with a baby crocodile.

Bob's sister Bindi, 11, hosts her own wildlife programme on Discovery Kids.

His mum Terri commented that her son is "a little Steve clone".

Steve Irwin was killed by a stingray while diving on the Great Barrier Reef in 2006.
