WASHINGTON, Nov 16, (Agencies): Steve Irwin is being fondly remembered by his children, Bindi and Robert, on Steve Irwin Day.

Bindi, 25, shared a touching throwback photo on Instagram, depicting her gently resting her head on her father's shoulder. In the caption, she expressed, "To the world, he will be remembered as the greatest Wildlife Warrior. To our family, he will be remembered as our world."

The post received an outpouring of heartwarming messages from fans, with one follower stating, "The world loved him, and the world loves your beautiful family! Thank you for doing what you do every day. He is proud of you - absolutely no doubt about it."

In his tribute, 19-year-old Robert posted a video on Instagram featuring his father discussing his conservation work and expressing a desire to be remembered for his "passion and enthusiasm" in the field. Robert's caption reflected on Steve Irwin Day, describing it as a day to remember their dad, "the greatest Wildlife Warrior on the planet," and acknowledging his enduring impact on future generations.
