Steve Irwin's son Robert Irwin celebrated his 17th birthday by sharing a touching video montage on his Instagram in honor of his late dad's memory. The video montage features the late crocodile hunter's moments with his son right from when he was born up to when he was a toddler and it left fans shedding tears. The late conservationist passed away in 2006 after a stingray barb pierced his chest while he was filming Ocean's Deadliest documentary. Robert was just two-years-old when his father passed away, but he has followed his footsteps in matters of zoo conservation.
