She revealed she had come across the turtle while on a walk with her dog.

"Early this morning I was walking on the beach and Onyx started barking at a pile of ocean trash that had washed during high tide," Bunchen explained. "When I came closer I saw this beautiful turtle turned upside down with a look of hopelessness and exhaustion in her eyes, her body knotted and entangled in a fishing net."

"I immediately started to free her from the net that was strangling her, but even after we got her untied, she was too tired to make her way back to the ocean," the model added. 

"I didn’t think twice, I just picked her up and carry her to the water.(amazing how adrenaline can make you stronger!) I felt relieved and so happy to see her swim away freely, grateful that I was there and able to help."
