Land Iguanas

Land Iguanas play an important role in the Galapagos; since they are herbivores, their vegetarian feeding habits are the reason for the dispersal of several succulent plants.  The land iguana lives on many islands in the Galapagos and the biggest adults can weigh up to 30 pounds.  They can survive long periods of time without the need to drink water.  These reptiles have a life expectancy of 50 to 60 years although the young ones are often eaten by rats, and feral cats while the older ones have to look out for dogs, and they are in competition for food with donkeys and goats.  The males have amazing courtship behavior consisting of aggressive chasing, territorial displays and a development of bright brown and yellow coloration in their skin.
