A scanned 6x6 Agfa slide, taken in the year 1967
The land iguanas have distinctive eyelids, external eardrums, dewlaps (throat pouches), each limb has 5 toes with sharp claws allowing them to climb.
They grow to a bulky girth and 3 ft (1 m) in length. Their yellowish-orange belly and brownish red back make them more colorful then their cousins the marine iguana.
The cactus they eat provides both food and water. They can go without fresh water for a year. Part of the adaptation to the drier environment includes a conservation of energy by slow movement. This makes the animals seem lazy or stupid. Land iguanas burrow into the ground creating tunnels which provides a place for nesting, shade during the day and protection at night.
