An adult Galápagos land iguana is enormous. Their average length is three to five feet. They can weigh as much as 25 pounds. This one looked menacing and prehistoric as its sharp-clawed toes and powerful hind legs thundered down the visitors’ trail. Yet somehow the intimidating aggression of this cold-blooded reptile was softened by the smirk on its scaly face. It obviously loves frightening tourists.
