I’ve had a few Iguanas that were over 6′ long and let me tell you, their teeth are effing razor blades, literally. A friend was eating strawberries before she came to my house, she love Judas, he was just shy of 5′. Never ever bit anyone in multiple years, you could rub his head, and dewlap, hold him, feed him, he was mad chill, but one time he smelt the fruit and decided to take a bite, he let go instantly when he knew it was bone. Her finger had 6 or so slices right down to the bone. It was like someone took a new razor and slicer her finger wide open. She was cool tho once we realized why he did it. No Bueno!
