This pic was shot during my recent trip to the Singapore Zoo. I was sitting there observing the Iguana and just all of a sudden this guy charged over to the another Iguana and i got a chance to shot this. I am not sure that this is part of their Behavior or was just a false charge. though i looked like a false charge to warn the other Iguana to back off.. these guys have been given proper OPEN space to roam around.
