One of the natural habitats of the marine iguanas are the Galapagos. The special thing about them is that they have a unique ability among all the other modern lizards - they can forage in the sea. If you wish to observe this unique creature, the most exciting events are iguanas nestings on Santa Cruz island in February and on Fernandina and North Seymour islands in March.
Generally, the mating season runs December through March, and nesting season from January to April. And this is the time when marine iguanas become more colourful. It is an amazing experience to witness male iguanas defending their territories.
