In 2006, fans mourned the loss of Steve Irwin, the intrepid "Crocodile Hunter," who died when a stingray barb pierced his chest while he was filming off the Great Barrier Reef.
The popular television star and conservationist was 44 years old when he was killed, and friends say that he died doing what he loved.
In a new book, Steve & Me, Irwin's wife, Terri, writes about her husband's legacy and her efforts to keep his work alive.
Terri Irwin met Steve in 1991 when he was working as a zookeeper in a reptile park in Australia.
Today, Terri Irwin operates the Australia Zoo that she and her husband built up together, and continues to develop television programs based on the Crocodile Hunter's unique approach to animals.
