Today while I was in the drive through I saw two rather large(10 inches long maybe?) brownish lizards have a territory type fight. They had knobs on the backs of their heads, and swollen looking ridges on their backs. I've never seen any lizard exactly like them, and was wondering if anyone had any ideas? If it had been possible I would have gotten pictures or captured them.
I tried googling and couldn't find anything even close. I'm in mid-north Florida, but I'm CERTAIN these weren't natives.
