Today's and yesterday's photo show the three most distinctive features of green iguanas (besides their color). Yesterday showed the dewlap hanging down from their chin. Today you can see the large round scale hear their jaw and the crest with long, sickle-shaped scales that run down their spine.
They often stay very still. They usually do not move very fast unless they are alarmed. My wildlife guide book says that the fastest that they move is when they bury the eggs a female has just laid. That makes sense. Exposed eggs would be vulnerable to lots of birds or other creatures.
We are showing photos of the architecture of London this week on our Viva la Voyage travel photo site.
